Where: Southern Texas (about 30 miles outside of Cotulla, in La Salle County). The specific location is a large ranch, approx. 7,000 acres, with a predominance of scrub-brushy-type vegetation around the lodge. Turkey, mourning doves, and quail are present for hunting purposes, although it's mainly a deer hunting ranch. I assume there would be plenty of other native birds on the grounds.
When: 2007, mid-to-late January, early morning (just before to just after sunrise).
What: My character wakes up early to birdcalls. What's he hearing? I'd like the 'first birds up'-- if I had set the story where I live, it would probably be seagulls, but I don't think that's going to work. :P
searches used: southern texas winter birds, southern texas early rising birds, morning birding southern texas january, and variations.
ETA: Looks like the inventively noisy mockingbird will work for this story-- you rock, little_details!
