MATAGORDA COUNTY – MAD ISLAND MARSH
CHRISTMAS BIRD COUNT
19 December 2011
The 19th running of the Matagorda County – Mad Island Marsh CBC occurred with strong warm winds all day and occasional light showers. Tides were high and there were few shallow mud flats. We were able to put a record 138 people in the field along with 4 boats to produce 244 species which was our 3rd highest tally. Even though this count has been able to record 334 species over its history, we still managed to add 5 new species, but we also missed 5 species which occur regularly on the CBC. The MANX SHEARWATER reported by Petra Hockey flying over the Gulf was voted by an overwhelming number of section leaders as the BEST BIRD of the Count.

The Nature Conservancy led all sections with people (50) and species (158). The Wildlife Management Area reported 152 species and STP had 147. The Peninsula Section led the CBC with 7 exclusive species, Matagorda-West and TNC had 5 each and Matagorda-East 4.
The theme of this count was determining the effect of The Drought. We expected lower than normal resident populations, marsh dependent species and insectivores. We did not expect that other areas were worst than us and there would be a major eastward and southward movement by many species that did not normally winter on the Coast. See what we found below.
RARITIES
The MANX SHEARWATER is mostly a pelagic seabird of the Atlantic Ocean. It is not expected at all in our area. Petra Hockey loves doing Sea Watches and she is one of the better birders in Texas at identifying pelagic species. We were fortunate when the shearwater being pushed by strong onshore winds flew along the beach in sight.
The ZONE-TAILED HAWK is a vulture mimic and typically breeds in the Hill Country and the Trans Pecos with most birds wintering in the Tropics. A few are found each winter in the Hill Country and South Texas. Mark Elwonger & Dale Friedrichs were able to obtain our 2nd record for this species at Lyondell.
The ROUGH-LEGGED HAWK is a bird of the Great Plains which typically does not winter south of the Pan Handle in Texas. This winter an unprecedented number of sightings have occurred along the Coast. Dennis Haessly was able to obtain a lengthy view of one on the Von Gonten Ranch.
The PRAIRIE FALCON is more of a northern Great Plains species. This season with extensive droughts in the state, a few have been reported along the Coast. Steve & Laura Gast, and Jim Stewart spotted one flying over the reservoir at STP.

YELLOW and BLACK RAILS occur in small numbers each winter along the Coast. They are difficult to survey because of their secretive habits in densely vegetated wetlands and propensity to not call. Several teams attempted to locate them during the day with no luck until Julie Sullivan and Adam Hickl started dragging a chain between two vehicles in a field of flooded unharvested rice on TNC. They were able to flush 2 Yellow and 1 Black.
WILSON’S PLOVER occur in very small numbers along the Coast during winter. We started noticing them roosting at the mouth of the Colorado River 3 years and we have been able to consistently find them on the CBC since then. Our Peninsula team was able to find a record # of 8 this season.

We first discovered MOUNTAIN PLOVER in the count circle last winter. I was able to locate it again during scouting, and Clay Taylor & Dane Ferrell were able to locate 24 during count day.

PARASITIC JAEGERs occur in small numbers in the Gulf each winter. It is not common for one to be near land in order for it to be observed.
Young LESSER BLACK-BACKED GULL’s are challenging to identify. They can easily be confused with young Herring Gulls. Petra is an expert on gull identification and she was able to photograph the one below.

The GREEN KINGFISHER is a tropical kingfisher of small streams. They winter regularly in small numbers from San Antonio to the south. There appears to be a small movement of them up the Coast this season. Michael Kennedy & John Tharp were able to locate one for our 2nd record on Lyondell property.
The HAIRY WOODPECKER is an uncommon species of East Texas forests that challenges many birders to identify it since it appears very similar to the smaller Downy Woodpecker. All Coastal reports are typically challenged by editors. Michael Kennedy was able to get our 6th report by seeing the bird side by side with a Downy.
The BROWN-CRESTED FLYCATCHER is another South Texas species that typically winters in the tropics, but a few birds occasionally get lost and end up going the wrong way. We have managed to find this species 5 times and this season Bill Baker with the STP group in their quest for 150 species managed to locate one.
The W. KINGBIRD is a strange bird. Although it is a common breeder in Texas, more of them over winter in Florida than they do in Texas. We have been able to find this species in coastal scrub 4 times. This year Bea Ann Kelly photographed one in the Peninsula Section.
The NORTHERN PARULA is a regular lingering neotropical warbler along the lower Coast, but we have always had difficulty in locating them. The STP team of Steve & Laura Gast and Jim Stewart obtained our 4th record of the species.
The YELLOW-THROATED WARBLER is one of those canopy foraging small warblers that lingers in small numbers along the river. It can be challenging to find in the tree tops. While we think it winters every year, we have only reported it 6 out of 19 years. This year it was found in the Selkirk area by John Faragher and Ron Weeks.

We have had only 2 GREEN-TAILED TOWHEEs in previous years. This season we had 16 during an unprecedented invasion by this species on the Coast. This species can typically be found in scrub enivornments of South Texas and further west.

The BREWER’S SPARROW is a bird of desert scrub that does not winter near the Coast. Chet Burrier again came through with a spectacular find by picking this bird out of a group of Clay-colored and Field Sparrows near Matagorda.
The HENSLOW’S SPARROW probably occurs in the CBC area every year in small numbers, but it is one of those mouse birds that are very difficult to locate. We have reported it 5 previous times. The species is known to have strong winter site fidelity and David Shackelford was able to locate one at the exact site where he had photographed one previously on the private ranches along the river.
We found our 1st LARK BUNTING last season with 1 bird at Selkirk. This year we had 26 with most being at Old Gulf. This is a bird that periodically occurs in large numbers in the brush country. This year they appear to be invading the Coast.

TRENDS
Marsh birds and insectivores occurred in much lower numbers than normal. Countering this raptors and sparrows occurred in above average numbers. Fulvous Whistling-Duck, Red-tailed Hawk, Wilson’s Plover, Herring Gull, Rock Pigeon, Eur. Collared-Dove, N. Flicker, Spotted Towhee, Green-tailed Towhee, Chipping Sparrow, Clay-colored Sparrow, Fox Sparrow, Harris’s Sparrow, and White-crowned Sparrow occurred in Record Numbers. In contrast, we missed Cattle Egret, Green Heron, Yellow-crowned Night-Heron, Ferruginous Hawk, Barn Swallow and Nelson’s Sparrow. The drought had both negative and positive impacts on the avian community using the area. It did add to diversity for species which we seldom see, but personally I could do without those western and northern birds if we had healthy and moist natural habitats in our area which would support some of the highest waterbird concentrations in Texas. I love the sounds of thousands of cranes and geese coming to roost in the evening.

TEAM WORK
Much of the results from this CBC are the direct results of the planning, leadership, coordination, and skills of our Section Leaders: Tom Morris, Sumita Prasad, Charlie Brower, Ron Weeks, Michael Kennedy, Bill Baker, Breck Sacra, Clay Taylor, Rich Kosteche, Julie Sullivan, Jim Renfro, Marc Ealy, Bron Rorex, James Arnold and Karen McBride.
This Christmas Bird Count is The Number One in the Nation from our Team’s perspective. It has shown national leadership in cooperative efforts between the birders, the landowners, the boat operators and the people of Matagorda County. It takes every body’s efforts focused on the end result to achieve our goals. Yes, we have a very diverse avifauna that is the product of a narrow forested corridor extending all of the way down the Colorado River to the Gulf that is bordered by an abundance of native prairies, brushlands and wetlands. An added factor is geography creates diverse ecosystems being in close proximity. This diversity would not be possible unless the landowners managed their land to maintain the productivity of the habitats, and it would not be possible to survey them unless they liked our project and permitted us access. All the birds in the world would not mean anything unless the interest, skills and cooperation of the Texas birders would not show up to conduct the count. We would count very few water birds unless our boat operators would not donate a day from their busy schedule as well as the use of their boats. We get great support from Texas Parks and Wildlife Department, The Nature Conservancy, the South Texas Nuclear Project, Lower Colorado River Authority and Lyondell-Basell for use of equipment, land and staff. Lastly, we could not afford to pay for the Great Supper at the Wadsworth Community Center, provide counters with t-shirts and pay their CBC activity fees without the generosity of the sponsors. We also thank Jim Harrison for the great art work for our T-shirt.
LEADERS: David and Marilyn Sitz. David has developed a great relationship with the landowners of Matagorda County and he is the person who obtains permission for the birders to access the private property. Marilyn does the fund raising, and the catering at the banquet. She also recruits volunteers to work at the banquet. This count would not be near as special without the leadership of Marilyn and her volunteers.
SPONSORS: Betty Clark, Matagorda County Birding & Nature Center, Bay City Nature Club, Texas Parks & Wildlife Dept., Lower Colorado River Authority, The Nature Conservancy, South Texas Nuclear Project Operating Co., Lyondell-Basell, Oxea Chemicals, A & A Bar-B-Que, All Star Real Estate, Bay City Abstract & Title, Conoco Phillips Sweeney Refinery, County Judge Nate McDonald, First State Bank, and Wells Fargo Bank.
LANDOWNERS: Lower Colorado River Authority, George Harrison, PCS Phosphate, Inc., Jack Miller, Carl Anderson family, Charlie Brower’s family, Roy Poinsett, Eugene Welfel, Barbara Holloway, Lyondell-Basell, South Texas Project Nuclear Operating Company, Julius Ledwig, Linda Joy Stovall, Bill Von Gonten, The Nature Conservancy of Texas, Texas Parks and Wildlife Department, Grover Ryman, Bill Doss, Ray Culver, and Becca Sitz.
BOAT OPERATORS: We appreciate the services and the boats provided by James Arnold, Bill Issacson, Jerry West and the Texas Parks & Wildlife Department.
