Frontera Audubon Thciket, 4/13/10

The past couple of days has seen a weird low pressure system over south Texas reminiscent of the tropical systems we see in July or August. So we're getting some rain which is grounding some of the migrant passerines and consequently I was able to see 61 species at Frontera Audubon Thicket today including 14 species of warblers. They included Worm-eating, Kentucky and this Blue-winged.



This Northern Waterthrush seems unusually dark.



I think this empid is an Acadian Flycatcher. Most empids bring up the rear of the spring migration, many not arriving till June. Acadians are one of the early ones.



Yellow-crowned Night-Herons nest at the Valley Nature Center and are frequently seen feeding at Frontera. I bet they nest here some day.



As I was leaving this morning I happened to see this "V" of about 100 double-crested Cormorants migrating north. I'm calling them Double-crested because they seem rather short tailed.
