Red-faced Warbler in CO

[Peter Gent]

All,

The Red-faced Warbler was seen yesterday at Burchfield State Wildlife Area, which is east of Springfield and about a mile from the Kansas line in Baca County.

There are 2 previous documentations of Red-faced Warbler in CO in the CBRC database:  https://cobrc.org/Reports/SpeciesDetail.aspx?id=413  The first was exactly 30 years ago on May 3rd 1993 at the Wheat Ridge Greenbelt in the NW Denver metro area (only seen for 1 day).  The second was on May 4th 2017 in a yard in Dolores in SW Colorado (only seen for 20 minutes).  So, it seems that the first few days of May is the time to look for this species in Colorado.

Cheers,  Peter Gent.

Chairman, CBRC.

I love rare birds from odd places, and found in odd places (maybe not so odd as the habitat looks good, just the location isn’t oft birded). 

Why would this bird stop in this location?  Well, looks like weather is an easy culprit this time.

The green circle in that link is the location of the Red-faced Warbler sighting. 

You can see the winds are from the south in NM where this bird can be seen at times and in certain habitats. You may also see a boundary where the winds are deforming to the east of the green circle (contracting in the north-south direction and pulling apart in the SE to NW direction). This boundary can be extrapolated westward to just north of where this bird was found. Those boundaries are often good places to go look for birds, and it panned out yesterday for those in the area lucky enough to chase it. 

In Spring, may the deformation/boundary be just to your north!

Bryan
