I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see

if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived.   Henry David Thoreau, Walden

Note from Derek:   Wow check out this guy's flight shot of a Short-eared Owl

from Parkhill Prairie!  He'd mentioned Parkhill Prairie in

an earlier email and Derek asked if he'd ever looked for

this owl there...and sure enough he goes out and finds

THREE there for his lifer list on Friday afternoon! Rodents

must be plentiful this year. Look at the eyes on that bird!

Robert Agnew sends us this note:  The Osprey you identified for me is still hanging around Lake Ray Hubbard and Miller Rd. 

I went back twice this weekend before the weather turned bad and both times the bird had a fish on his perch. 

Unfortunately, he had taken favor to a snag about 300 feet from the road (he had been frequenting a snag about 175' from the road).

He is looking for other photo enthusiasts!  (Image was cropped to save space and get detail)

This osprey was spotted by Derek off Miller Road in Rowlett as we scouted out birding spots

for the upcoming Dec. 21 Lake Ray Hubbard Christmas Bird Count:

 

 

 

 

This summer, Courtney Blevins, Fort Worth Regional Forester for the Texas Forestry Service

presented the City of Garland and the Parks and Recreation Board/Tree Board the official

Tree City USA  plaque, street signs and Tree City U.S.A. flag. Congratulations Garland!!!

 

Bob Woodruff Park is in Plano and has a larger area of forest and open fields than Spring Creek.

Birding is excellent most months of the year.    Peter Assman's bird records are here:

During the work day removing invasive privet, Ann McKay found two new plants to add to our list, one

of which is an escape:  Chinese Holly (Ilex cornuta) and Reverchon's Hawthorn (Crataegus reverchonii).

Thanks Ann and thanks to all who helped remove Chinese Privet and Japanese Privet today.

Oct. 29  Rat Snake and Texas Garter Snake field notes (Oct. 26):

 

Leighton Thompson sent us these professional field notes and accompanying images. Thanks Leighton, its

about time we had a real herpetologist visiting Spring Creek!

 

Here attached are a few pics of a Rat Snake that I observed sunning itself on the trail (Rat Snake figure 1 in-situ)

at the 1787 Holford location on 10/26/2008 at about 5:20pm.  At first glance the specimen appeared to be a fairly

typical (in my limited experience in this region) neonate Texas Rat Snake (Pantherophis o. lindheimeri),

however upon further examination, two black stripes on the underside of the tail were noted (Rat Snake figure 2).

These stripes reportedly occur only within subspecies of Pantherophis guttatus - the Corn Snake / Great Plains Rat Snake clade,

the latter of which has also been documented in this region of Texas. I recorded a few key data points on the morphology

of this specimen and cross referenced them with data on both Pantherophis o. lindheimeri and P. g. emoryi for comparison

((Texas Snakes, Werler & Dixon, 2000.), & (Amphibians and Reptiles in Colorado: Revised Edition, Geoffrey A Hammerson, 2000.)).

Here are some results:

P. g. emoryi:

1.)  Typically 42-55 mid-dorsal blotches.
2.)  27-29 scale rows midbody.
3.)  2 dark colored stripes on underside of tail.
4.)  2 or more rows of blotches on sides of body.

P. o. lindheimeri:

1.)  Typically 27-37 mid-dorsal blotches.
2.)  27 scale rows midbody.
3.)  Underside of tail gray in color.
4.)  1 row of smaller blotches on sides of body.
5.)  Skin between scales (& some times scale edges) reddish in color.
6.)  Top of head in neonates/juveniles slightly darker in color than rest of body.

Pantherophis sp. - (Spring Creek Preserve):

1.)  31 mid-dorsal blotches (consistent with P. o. lindheimeri).
2.)  27 scale rows midbody (consistent with both species).
3.)  2 dark colored stripes on underside of tail (consistent with P. g. emoryi).
4.)  1 row of smaller blotches on sides of body (consistent with P. o. lindheimeri).
5.)  Skin between scales - reddish in color (consistent with P. o. lindheimeri).
6.)  Top of head in slightly darker in color than rest of body (consistent with P. o. lindheimeri).


The specimen appears to exhibit morphological traits consistent with the Texas Rat Snake with

 the exception of the striped under-tail, common to the Great Plains Rat Snake - which have been

documented in both Collin and Dallas counties, calling into question the potential for this specimen

to be an intergrade between these two closely related (Collins & Taggart, 2008.) species of rat snake,

 respectively.  I would respectfully suggest that the data be reviewed by a qualified herpetologist,

& until or unless further study can be made regarding the population of Rat Snakes in the preserve

and or area, I would list the photo(s) as a neonate Texas Rat Snake.

OTHER PHYSICAL DATA COLLECTED:
Snout-Vent Length: approx. 305mm.
Tail Length: approx. 65mm.

PART 2:

 

Here attached are some pics of a what appears to be a neonate

Texas Garter Snake (Thamnophis s. annectens) that I observed at approx. 5:30pm

on 10/26/2008. I discovered the specimen beneath a piece of rusted metal of the

south bank of the creek at the 1787 Holford location (Garter Site figure 1).

Due to the similarity of the Western Ribbon Snake (Thamnophis p. proximus) in

appearance, I have listed some morphological differences on both species

(Texas Snakes, Werler & Dixon, 2000.) as well as the specimen observed, below:

Thamnophis s. annectens:

1.)  Striation of dark pigment occurring between upper lip scales.
2.)  Color on side stripes occurring on scales 2-4 above belly plates.
3.)  Dark dorsal color encroaching onto outer edges of belly plates.
4.)  Tail (below anal plate) comprising less than 1/4 of total body length.

Thamnophis p. proximus:

1.)  Upper lip scales light in color.
2.)  Color on Side stripes occurring only on scales 3 & 4 above belly plates.
3.)  Tail below anal plate comprising nearly a third of the total length.

Thamnophis sp. - (Spring Creek Preserve):

1.)  Dark pigment between upper lip scales (Garter figure 2 & Garter Portrait 1) (consistent with T. s. annectens).
2.)  Lateral side stripes occurring on scales 2-4 above belly plates (Garter figure 2 & Garter Portrait 1) (consistent with T. s. annectens).
3.)  Dark dorsal color encroaching onto outer edges of belly plates (Garter figure 2) (consistent with T. s. annectens).
4.)  Tail (below anal plate) comprising less than 1/4 of total body length (Garter Portrait 2) (consistent with T. s. annectens).

The morphology of this specimen appears consistent with that of the Texas Garter Snake .

Oct. 21:

Peter Assman posted his latest bird list for the Plano Outdoor Learning Center and Bob Woodruff Park:

 

Plano Outdoor Learning Center / Bob Woodruff Park
10/18/08 & 10/19/08

In the woods behind the Learning Center on Sat I had 2 brief glimpses of a bird in flight that I'm 92.5% confident
was an American Woodcock. The bird flew from the path flushed when I rounded the corner. Just as it flew,
an outdoor education class came by and stopped right in front of the path where the bird had flown to discuss
forest succession.. I waited until they left and searched the area, and after a while I got a second brief glimpse
of the bird in flight. It had rounded plain brown wings and its wings made a fluttering sound as it flew
into the woods. I returned Sunday morning but couldn't re-find it. Lots of winter birds arrived this week, sparrows
including a group of Swamps on Sunday and a single Fox on Sat morning.  Very lively both days.

Fri Oct 18 a pair of Monk Parakeets were feeding on the ground with a Great-tailed Grackle flock at the north end of
UTD campus (Collin County).

Oct. 15

Thanks to a call from Derek....hundreds of monarchs were seen from Richardson to Spring Creek Forest late this afternoon after

the cold front pushed them southward on their way to Mexico.  Capturing this was next to impossible on camera since they were

scattered and from 10 feet to as high as my eyes could see.  Here are some early fall colors seen at the Preserve as the monarchs

migrated south...Mexican plum, seed heads of coneflower, broomweed and asters color the foreground..

be tied together with other municipalities and neighborhoods...

 

Oct. 6

Martin Selznick mailed us these notes and great images from his hike yesterday at Breckinridge Park along Rowlett Creek

north of Spring Creek...Thanks for sharing this!

 

Here are a few pics from yesterday.  This is the first venomous snake I have come across at the local (Breckinridge) park…..

but it did not smile for the camera.  I was actually looking for green grass snakes, but the copperhead

was a good alternative.  It is a good thing I was looking for snakes, otherwise I would have stepped on it…..

no joke there…..really.  I had glanced up for a moment to look for owls, but then I went back to looking along the brush

…..and there it was…..2 steps in front of me. 

 

Oct. 4

 

Three interesting migrants at Spring Creek Preserve....Clay-Colored Sparrow (FOS), Wilson's Warbler, and Monarchs.

Fall colors in Poison Ivy, Mexican Plum, Virginia Creeper and goldenrods/prairie asters are abundant.

 

Sept. 29   Two new plants to our list found along the wet margins of Spring Creek:

Boy Scout Troop 1199 helped the Society cut back invasive hardwood seedlings today at the Preserve.  We also had

help from Texas Master Naturalist Jim Varnum and Dallas Chapter National Audubon Society's Sandy Schriever. 

With loppers, saws, and pruning shears along with roundup they helped halt the encroachment of Bois D'Arc, Honey locust, elm, cedar elm,

and other invasive plants . Thanks all for a successful workday.

No better way to start off Labor Day than birding during migration!  Will post the list to Texbirds too. B.Gibbons just called saying he found n photographed a Sabine's Gull near Dalhart in the TX Panhandle on his way to Colorado.  I emailed Dale Clark about the whitish butterflies we saw yesterday and today and he seems to think they're the White Angled-Sulphurs. I guess cabbage whites would be smaller and not such strong fast flyers, but I dunno for sure.  Will have to wait for a nice perched look before fully enjoying the tropical lifer

Peter Assman shares his bird observations for late summer...

Summer bird sightings, June 1 - July 31, 2008
Plano Outdoor Learning Center / Bob Woodruff Park

Not much to report. Very hot and dry.

A Yellow-throated Vireo spent the summer (sightings on 6/7/08, 6/14/08, 
7/5/08, 7/13/08). Didn't locate a nest, didn't see or hear more than 
one bird at a time, but the bird was on territory all summer and 
produced loud and persistent songs until early July. Last heard this 
weekend (Aug 9, brief burst of song from the vicinity of the Learning 
Center).

Black-chinned Hummingbird (female) photographed on the nest near 
Rowlett Creek on the path to the Outdoor Learning Center 
(http://www.utdallas.edu/~assmann/POLC/polc_0708.html). Male perched 
nearby on nearly every visit.

Northern Parula - two pairs likely nested in different locations 
along the creek, singing heard on nearly every visit.

Very few Yellow-billed Cuckoos in the area this summer.

Elsewhere: 

Swainson's Hawk sightings on 6/13/08, 7/15/08, 7/30/2008, 7/31/08 near 
Custer Rd and Plano Pkwy (Collin County). Two recently fledged 
juveniles perched on a telephone pole near the corner of Custer Rd & 
Plano Pkwy on July 30, 8:15 AM; one was perched in the same spot on 
several dates between July 31 and Aug 10. Probably nested in the 
vicinity.

American Kestrel sightings: 6/15/08, 7/13/08, 7/30/2008, 7/31/08 (all 
single birds) near the railway tracks north of UTD campus (Collin 
County
).

Masked Duck female found by Bob Stone at Kaufman Marsh 14-Jun-08. I 
took photos, but Peter Billingham's are better quality.

2 Anhingas soaring over the UTSW rookery on July 19 (Dallas County).

July 22

 

Jerri Kerr sent us this note on a new bird for Spring Creek:  a Greater Roadrunner (Geococcyx californiansus)

This brings the total number of species to 170...thanks for this report Jerri.

 

 

 I wanted to let you know that a coworker friend of mine,
 Mark Durbin  (copied) has reported seeing a Greater Roadrunner dash out
 onto Holford  Road near the entrance to the east-side parking lot at
 Spring Creek Park  Preserve.  Mark is familiar with Roadrunners and is
 positive of the i.d.  It sounded pretty far north and east for a Roadrunner, so I
 checked your  bird checklist for the preserve and see that you do not
 have one listed  as of the 4/27/08 update.
 
 

July 21

A female Ruby-throated Hummingbird nests over Spring Creek in a Green Ash....last year she nested in this same spot!

If anyone wants to donate a stronger telephoto image than this Nikon 200 mm feel free thanks! Again she camouflaged

the nest with liverworts growing on the stream bank nearby...

 

 

 

 

The Smithsonian Field Guide to the Birds of North America by Ted Floyd is on bookshelves.  It comes with 587 downloadable bird songs.

Harper Collins Publishers, 2008  ISBN 978-0-06-112040-4          The photos and songs are excellent!

 

Don't be surprise if, one day, you see a monk parakeet at Spring Creek since they seem to be expanding their range....(photos courtesy

of Barbara Keeler..thanks!) These images were taken in Addison, Texas.

 

 

 

June report:  Mountain Lion???

 

A couple reported seeing a mountain lion (Puma concolor) crossing Holford Road on the north side of Spring Creek around 8:30am recently. 

They exclaimed about the "long tail" on it and verified it on Google when they arrived home. This particular area has the largest forested portion along

Spring Creek.

 

UPDATE: Tom Frey's message regarding the mountain lion sightings......

I spoke with Gary Chambers, Firewheel Golf Park, he has seen a large cat, long tail, several times, especially during the last course construction.  Also have a report from Bill Smith, Engineering Dept., who saw a large cat with long tail along Brand Road near TalleyRd./Provence.  This morning a contractor working in Winters Park, east of Hawaiian Falls, reports seeing a large cat with a long tail in the old amphitheater.

 


 

June 30  Thanks to the last field post by James Rusk, I went to Long Branch and saw abundant Rattlesnake Master and a few Bluebells. 

(Eustoma grandiflorum).  This morning I visited the remnant gilgai prairie located off a frontage road on I-30 near Loop 12 exit. 

This and Long Branch Prairie are probably among the most endangered habitat within the metroplex.  Only 4-5 plants found compared to a

hundred or more only a few years ago (4th image)... Development in closing in on the east and west borders of the prairie....

it will probably disappear in the near future.

 

There are gilgai here, which is hard to image since most are gone.. the bluebells are facultative wetland plants and usually indicate seasonally wet prairies

in Texas.  Native plant & prairie organizations may want to visit this urban jewel as well as the larger Longbranch Prairie (aka Pioneer Prairie), both

only a few miles from downtown Dallas...

 

 

 

 

June 28 James Rusk sent this field report from Long Branch Prairie (aka Pioneer Prairie).  Thanks James!

 

I went walking over Longbranch Prairie today. Even though we are about 4 inches below normal rainfall, there was some interesting flora.

Bluebells are blooming a little early this year (they usually don't bloom until well into July). I counted about 20 plants.

I also saw many colonies of Rattlesnake Master (aka Button Snakeroot). And, for the second year in a row, I found a colony of Cardinal flowers.

June 23 Martin Selznick sends us these photos...thanks!

If any of the members like to watch herons & egrets, they have been fishing at the pond in the commons area of the Hills of Firewheel.  The pond level is down for maintenance, so there is a wide shoreline along which the birds can wade.  Last night there were a few green herons & a snowy egret.  The big blue & the great egrets have also been hanging around there.

   


 

Image above is from Google Earth showing effects of urbanization on North Central Texas farmlands (former

Blackland prairie) and riparian forests as developers build in traditional archaic ways....it was a

great image to show former and current land use since Google had merged old and new imagery

on this boundary in Allen, Texas near the 121 and Central Expressway 75 interchange. This is upper

Cottonwood Creek and is a tributary to Rowlett Creek like Spring Creek.   Alternatives to this type of development

are found on websites such as  

 

Smart Growth Online and Vision North Texas and

North Central Texas Council of Governments site (NCTCOG)

This is a good presentation of sprawl in North Central Texas as it engulfs and surrounds our last remaining open spaces, prairies, and woodlands…..a must for those of you who are concerned about rampant development in your environment as well our disconnect from the natural world.   After seeing this Dean Terry movie you will realize even more how much we need Spring Creek and open spaces.    Accompanying photos for the documentary are at http://www.flickr.com/photos/therefore/sets/436293/detail/

 

June 17 James Rusk has this field observation on our butterfly populations.....

 

 

I've noticed a large drop in the North Texas butterfly population this year (you probably have too). Dale has a note about it at:
http://www.dallasbutterflies.com/Wherehave.htm
Just thought you might want to add that to your field notes.

June 9

Called one of the most striking wildflowers in north-central Texas, this species is a favorite for ruby-throated hummingbirds.

These separate colonies were found in the small rocky prairie south of the Special Events Center  4999 Naaman

Forest Boulevard Garland, TX 75040-2734.

 

 

Peter Assman posted his bird sightings for March-May on a spreadsheet for birders at http://www.utdallas.edu/~assmann/POLC/polc_spring08.html

Quite a nice list...and we put this our website since Spring Creek is a tributary to Rowlett Creek, where Peter visits a lot.  For those of you who want

to visit Bob Woodruff Park or Plano Outdoor Learning Center here is a map:

 


 

While this isn't a field note, we should think about water use during the summer as well as year round

enjoy reading these water trivia and facts......

 

  

An ephemeral channel becomes active during a recent rain

at Spring Creek Forest (above).

 

There is the same amount of water on Earth today as there was 3 billion years ago.

Three percent of the water on Earth is freshwater and only 1 % is avaiIable for human consumption.

Sixty-six percent of a human being is water.

Seventy-five percent of the human brain is water.

Seventy-five percent of a living tree is water.

You could survive about a month without food, but only 5 to 7 days without water.

On the average, each American uses about 160 gallons of water a day at a cost of 27 cents.

Bottled water may cost up to 1000 times more than municipal may not be as safe.

Two-thirds of the water used in an average home is used in the bathroom.

Typically 4 to 6 gallons of water are used for every toilet flush.

On the average, a person uses 2 gallons of water to brush his or her teeth each day.

A 10-minute shower uses about 55 gallons of water.

A leaking faucet can waste up to 100 gallons of water a day.

The average person spends less than 1 % of his or her total personal expenditure dollars for water, waste water, and water disposal services.

There are about 60,000 community water suppliers in America.

Pubic water supplies must meet or exceed Environmental Protection Agency standards. Many public water supplies consistently supply water that is much better than the minimum standards.

The Amendment to the Safe Drinking Water Act in 1986 increased the number of contaminants to be regulated from 26 to 83 and expanded EPA’s enforcement authority.

If a drinking water supplier violates any federal standard, the utility by law must tell the customer.

Current water treatment methods are designed to make drinking water clear and to kill germs.  These treatments, however, do not remove pharmaceuticals, endocrine disruptors, mercury, pesticides, and other contaminants.

The pipes that carry drinking water from treatment plants to homes are regularly cleaned. This does not, however, remove any contaminants that are in the water after it leaves the treatment plant.

It takes about 39,000 gallons of water to produce the average domestic auto, including tires.

It is not safe for hikers and backpackers to drink water directly from remote streams.

One gallon of gasoline can contaminate approximately 750,000 gallons of water.

One quart of motor oil can pollute 250,000 of water.

You can help prevent pollution of drinking water sources by carefully disposing of the chemical products you use in your home.

Water Shortages

Unsanitary waters cause more than 15 million deaths each year. This number of deaths will probably escalate with population increase and potable water shortages. If a climatic phase of severe drought strikes, the present 15 million deaths per year could rise to more than 25 million deaths per year.

The wars for entrepreneurial control: These wars are evidenced by transnational corporations purchasing  water companies and resources around the world. People would cannot afford to pay their bills generally have their water shut off and are forced to used polluted water, often with water-borne diseases. In one African community, this resulted in a six-fold increase of dysentery.  

Water shortages are worsening in many regions and the Worldwatch Institute says that by 2025, 40 percent of the world’s people will be living in countries experiencing chronic water shortages or water stress.

The World Bank predicts that water will become the natural resource most likely to cause wars in the 21st century.

 Already, more than a billion people on the planet are without safe water. And continued population growth will only make these problems worse.

 For an interesting view of your “water footprint”, click on Waterfootprint.org

 Water is nature’s gift and cannot be owned and turned into a commodity.

June 2, Peter Assman's report for Plano Outdoor Learning Center and Bob Woodruff Park..

 

Migration must have been incredibly successful this year-
because it left no stragglers at all! The 2nd half of May
was hot, dry, windy, and migrant-free. An American Kestrel
is showing up regularly just north of UTD, possibly spending
the summer here. Barely reached 40 species on Saturday.
But I did find a huge wolf spider. Some pictures:

Spring migration is here!  This morning we saw 13 warbler species at Prairie Creek Park in

Richardson...including Chestnut-Sided, Bay-Breasted, Blackburnian, Magnolia, and Nashville Warblers.

The weather front this morning made conditions ripe for seeing birds today and hopefully all week

at this location.  Derek will post the list on TX Birds (Texas Rare Bird Alert)

Ft.Worth Audubon will have a group looking for these birds on Saturday at 8:30 am...

April 28

Longear Sunfish males guarding their nests in Prairie Creek (tributary to Spring Creek).  (Texas Parks & Wildlife web site: 

"Spawning occurs throughout late spring and early summer. Males scoop nests out of gravel bars. Females are enticed to

lay their eggs on a particular nest by a male who swims out to meet her, swimming around her rapidly and

displaying his brilliant spawning colors. After the eggs have been laid, males chase the females away and guard

the nest vigorously despite their small size, chasing away all intruders. Males may continue to guard the nest for

 a week or more after hatching, until larvae have dispersed."  The males are striking with turquoise fins and

orange bodies, making it our most colorful sunfish in Texas.

Good news! Marvin reports that two of our bluebird boxes have babies...thanks for checking them Marvin. Unfortunately others had

wasps and/or ants....


Charles Torello stands beside a huge American Elm (Ulmus americana)measured a few years ago at 157 inches in circumference

This giant is located in Spring Creek Forest between N. Garland Ave. and Namaan Forest High School well off any

beaten paths....  Check with this Dallas Wild Life leader and join him April 20 to explore and work on trails....

April 6

 

Spring migrants are coming through...Audubon's, Yellow-Rumped, Parula, Orange-crowned, Nashville warblers,

White-Eyed (4), Solitary vireos (3), Blue-Gray Gnatcatcher, Grasshopper Sparrow (3)

Rough-keeled Green and Lined Snakes (new on reptile list by Derek) also seen.

 

Work day April 5 was fun clearing out nuisance vegetation around the prairie edges, where it encroaches unless controlled...

Several hawks, Harris's sparrow, and other birds were around as we cleared.  The City of Garland Parks & Recreation bush-hogged

the prairie, helping keep out the invasive hardwoods and other plants....thanks Parks & Recreation! President Barbara Baynham

and her husband are in the far left of the first photo. Leadership Garland and Master Naturalist programs also helped!

 

 

March 26 Colors of spring with new leaves on the oaks and blooming Mexican plum...

 

 

March 18 Big rain...even at 5:23 PM the rains keeps coming and rainfall so far is around 3.41 inches. These are photos of Spring Creek

at Holford Road around 2:45 PM today: We met with Tom Frey on site earlier to discuss mowing the Preserve on the western side of Holford

Road to control invasive hardwoods and nuisance vegetation...but this will certainly be delayed for a couple or more weeks now. There

was concern about disturbing Bluebirds but none have been spotted in the vicinity or around our bluebird boxes so far.

 

 

March 12

According to Dale Clark's site, Henry's Elfin (Callophrys henrici) flies
from late-February to late-March in our area, and primarily feeds on Eastern Redbud (Cercis canadensis),
as well as Mountain-Laurel (Sophora secundiflora),Texas Bluebonnet (Lupinus texensis), Yaupon Holly
(Ilex vomitoria), Texas Persimmon (Diospyros texana). The ones at Spring Creek seemed to be fond of perching
on Mexican Plum and Eastern Redcedar.
Update: photo on right is black tiger swallowtail male (March 13)
 

Today's butterflies:

Cabbage White (Pieris rapae) - 1
Falcate Orangetip (Anthocharis midea) - 1
Orange Sulphur (Colias eurytheme) - common
Southern Dogface (Zerene cesonia) - 1
Cloudless Sulphur (Phoebis sennae) - 1
Sleepy Orange (Abaeis nicippe) - 1
Henry's Elfin (Callophrys henrici) - 3
Question Mark (Polygonia interrogationis) - 1-2
Red Admiral (Vanessa atalanta) - 1
Common Buckeye (Junonia coenia) - 1-2
Goatweed Leafwing (Anaea andria) - everywhere
Juvenal's Duskywing (Erynnis juvenalis) - 1

I think the white one we saw at Bob Woodruff was a
female Falcate Orangetip. They do indeed show a black
spot on the forewing, which I had forgotten about. It
looked falcate-ish in flight for the brief looks that
I had.

March 10   Martin Selznick sent us these photos of a nice juvenile Cooper's Hawk...thanks Martin! Derek has written up a blurb on how to tell this species from the

Red-Tailed Hawk. This is the "chicken hawk" of the old days despised by chicken farmers but feeds on English Sparrows, field mice and

is beneficial to the woodland ecosystem.

 

      

I agree this is a juvenile Cooper's Hawk. The smallersize, slimmer shape, and longer tail separate
Accipters from Buteos, so it's not a Red-tail.  It is a juvenile based on the dark brown upperparts and
underpart streaking. It is a Cooper's rather than a Sharp-shinned, because this bird appears to have a
round-tipped tail (not square or notched), and the streaking underneath is mostly dark blackish-brown,crisp
narrow tear-drop shaped, fading away towards the whiter belly. A juvenal Sharp-shinned on the other hand 
would showthicker (and often paler brown or red-brown) underpart streaking/spotting extending down through the belly.

March 8...This report of destruction of monarch wintering habitat is alarming...we may not see many Monarchs around Spring Creek in the near future.

Feb. 19 Jim Varnum reported Trout Lilies yesterday...thanks Jim!


Re: Spring Creek Forest Preserve (1770)
Stephanie and I found trout lilies along the back trail to the prairie yesterday afternoon (2/18).  Maybe 50 plants, just a few with flowers, none fully open.
We found none along the long concrete path and between the path and Holford Rd.
Lots of Elderberry coming up.
And a sapsucker.
Someone dumped a large log and a section of tree trunk in the parking lot.


Feb. 11

Derek officially submitted the data for Ray Hubbard the results can be seen by anyone now, at
http://cbc.audubon.org/cbccurrent/current_table.html  type in TXLR count code and there it is!

Enjoy Birding on the Great Backyard Bird Count

 The Great Backyard Bird Count is February 15-18. Organizers at the Cornell Lab of Ornithology and Audubon say they are hoping eBirders will go the extra mile to report their sightings to GBBC this year. Last year, participants reported more birds than ever before: over 11 million individuals of 613 species, and broke the all-time record for total checklists: 81,003. Greater participation ensures better coverage of birds at locations all across the United States and Canada, and provides a more reliable record for tracking bird populations. If you would like to see your counts appear on GBBC maps and tables, please send your counts to the GBBC web site in addition to eBird. For more information about this year's Great Backyard Bird Count, including instructions, birding resources, and images from this year's count, visit GBBC.

Google Maps now features images of street addresses so type in 1782 Holford Road , 1708 Holford Road, and 1520 Holford Road to see views of Spring Creek Forest and Preserve entrances and a view of Spring Creek. The exact street addresses don't match actual street addresses since map accuracy is not 100% (for now).

Peter Assmann posted his bird bird list from Bob Woodruff Park. Spring Creek is part of the same Rowlett Creek

watershed where he observed these birds:

1/26/08
Plano Outdoor Learning Ctr / Bob Woodruff Park
Dense fog 8 AM, clearing by noon, birds very active

Purple Finch, Pine Warbler, Am. Pipits, snipe, both nuthatches
(but no Rusty Blackbirds so far this year)

Here are two photos of finches, one male, one female:

 http://www.utdallas.edu/~Assmannn/P1264863.jpg
 http://www.utdallas.edu/~Assmannn/P1274997.jpg

I was fairly convinced that the male finch was a Purple 
(based on calls from the vicinity) but there were also 
House Finches nearby, and the field marks seem obscure. 
The bill is not visible and the picture is slightly out 
of focus, and my question is: what field marks would make 
this either Purple or House? Any thoughts? 

I returned Sunday and re-found the birds (in the woods next to
the Learning Center) and took pictures of the female. Sunday
added to the list below 3 American Robins, 2 Brown Thrashers, 
Hairy Woodpecker, Belted Kingfisher, Eurasian Collared Dove,

January 25

A wet field of dropseed and little bluestem with invading Eastern red cedar ...taken during a light rain today...

The dampened grasses revealed their earthy colors as it rained.  Unfortunate these remnant escarpment

prairies are becoming a rare sight north of Spring Creek Forest and Preserve as developers grab the last

parcels of land adjoining President George Bush Tollway in Garland, TX.
