Hey all,
Jason Zolle, Isaac Boardman, and I had a great morning of birding around Aguilar today. I hope this email can provide a summary of the sightings along with strategies for birding the town.
The best area is a stretch of the Borrego Ditch, from here (37.398142, -104.656763) on San Luis Ave to here (37.396419, -104.657742) on S San Antonio Ave (See first linked habitat picture). This has had at least two American Redstarts, at least one Northern Parula, Hooded Warbler, Kentucky Warbler, and Worm-eating Warbler. The Kentucky was not seen again today. The Worm-eating Warbler was extremely cooperative, hanging around the first set of coordinates and our group saw it on at least five separate occasions. The Hooded showed well for multiple observers today.
Another productive area is another section of the ditch here (37.400045, -104.652817), on South Ave between East St and Santa Rita St. This area had a Blackburnian Warbler yesterday and Northern Parula(s) both days, and a Yellow-throated Warbler today. It also had the best views of the large Leiothlypis (Orange-crowned and Virginia's Warblers) flock. One quick note about the Orange-crowns: of the thirteen our group had today, almost all appeared to be confirmable as the Pacific subspecies, L. c. lutescens.
There is another creek that runs through the north side of town (37.402799, -104.656279). Although it is currently dry, it provided a Tennessee Warbler yesterday and today.
One other area that seems to be productive is here (37.401461, -104.650146), along 1st St. Luke and Pablo had Northern Waterthrush and Nashville Warbler here on 05/01.
Happy birding!
