As I forgot to report on a quick trip I took out to the Katy Prairie on November 24th, I'll give a quick summary here.
I was hoping for sparrows at the Cypress Creek bridge on Sharp Road. All I actually saw was a Downy Woodpecker that was looking rather agitated.
There were a couple of Vesper and Field Sparrows along Longenbaugh. However, they were greatly outnumbered by Savannah Sparrows.
My final sighting was of the young Scissor-tailed Flycatcher that I'd been watching for weeks on Longenbaugh and that seemed to have decided not to leave when the other Scissor-taileds migrated in late October.
There have been no reports of a Scissor-tailed in our area since November 24th, so I guess the Longenbaugh bird finally reaized it was time to head south.
