We get a Norther Flicker just about every year on SPI but they are usually of the eastern "yellow-shafted" race. I don't know if I've a "Red-shafted" in the Valley before. Here's my try at a video. Would be better with some editing.
Other stuff around the Convention Center was several Nashville and Tennessee Warblers.
And a rusty tailed Hermit Thrush
Back at Sheepshead a Cooper's Hawk perched in the tangled vegetation with some bloody remains in its talons.
Nearby a small flock with a couple of warblers, an Indigo Bunting and a Blue Grosbeak approached the water drip seemingly oblivious to the nearby accipiter.
Then overhead I heard a loud whistled "see-ooo". The long staying Crimson-collared Grosbeak was vocalizing right above me and I could not find it to save my life. Oh well. Then I figured I would like to keep the grosbeak from being a second course to the Cooper's Hawk's meal. So I hopped the fence and flushed the raptor. He knows where the birds are and will probably be back but I did what I could to try to keep the Crimson-collared Grosbeak around for another week for the RGV Birding Festival.
