New Additions to Collections

Although being in the field regularly is always preferable, bad weather and the threat of bad weather have kept me indoors of late. Birding time has been transformed into computer time: additional images have been added to the Stalking the Hunters: Additional ImagesTexas Ducks, and Galveston Island Birds collections. Expect more in the near future.

Loggerhead Shrike with snake at Brazos Bend State Park, Texas.
This Loggerhead Shrike has just seized a snake. Shrike numbers increase significantly during the cooler months at Brazos Bend State Park. Shrikes, like other birds with black masks are challenging to photograph: the light has to be just right to capture a catchlight and a well-defined eyeball. Photo taken near water’s edge, Pilant lake.
Thermoregulating Great Blue Heron at Brazos Bend State Park, Texas
Thermoregulating Great Blue Heron? at Brazos Bend State Park, Texas. Herons and egrets can be seen occasionally in this sort of pose on hot, sunny days. It has been speculated that this is related to thermoregulation, but to my knowledge the details remain obscure. On the sweltering days when I see this sort of behavior, it would seem that warming up in the sun would be the last thing a bird would want to do–unless they are sterilizing parasites or pathogens thermally while employing gular fluttering or “panting” to keep their brains from frying. Photo taken at Pilant Lake.
