Black-throated Green Warbler in So. Texas

I finally got down to So Texas after a friend who wanted to spend some time in Colorado came to stay in my house while I'm gone. Birding has been a bit hit and miss due to frequent drizzle and light rain which has kept me from getting many photographs yet. I did enjoy birding, albeit in drizzle, at Frontera Audubon in Weslaco today. I found this Black-throated Green Warbler in a mixed flock with a Black-and-white Warbler, two Ruby-crowned Kinglets, a White-eyed Vireo, a couple of Black-crested Titmice, and a couple of Orange-crowned Warblers. At one point this mixed flock was joined by a Golden-crowned Warbler, a very rare bird that had been found at Frontera yesterday. I got a nice but brief good look at cool rare vagrant but it moved around in the scrub quickly so didn't get a chance to photograph it. I got two more very brief looks at it again but it moves around where it is was a challenge to follow. There had also been a female Crimson-collared Grosbeak found at Frontera yesterday but I didn't find it. I also spotted an Ovenbird that was also working low in the scrub not far from the Golden-crowned Warbler. SeEtta
