Rarities Found This Week

Without a doubt, this weeks most interesting report was of a possible immature Lesser Black-backed Gull at Hornsby Bend on 8/27. I am awaiting details for this; it would be an exceptional find.

A Blue-winged Warbler was located on a private property in Bastrop County 8/29

Northern and Louisiana Waterthrushes are listed in the Travis Audubon Checklist as rare–perhaps (I think) a bit of an error. Both species were observed side-by-side (which is cool) at Camp Mabry in Austin on 8/26.

A Northern Waterthrush was at Nicholas Dawson Park in South Austin on 8/28

An Ovenbird was photographed at Warbler Woods in Guadalupe County on 8/28-29

A Yellow-throated Warbler migrant was a park-first for Commons Ford Park in western Travis County.

Continuing Birds for Previous Weeks

A Prairie Warbler found on August 25, continued to please numerous Hornsby Bend birders/listers 8/25-8/28 Travis County

A Yellow-throated Vireo re-appeared (same tree) at Big Webberville Park after a weeks long absence in eastern Travis County on 8/26

Couch’s Kingbird is enigmatic, but reasonably regular at Big Webberville Park. 8/26

Yellow-throated Warbler, a breeder at the Colorado River and Highway 360, lingers late into the season. 8/30
