Hi Texbirders,
I volunteered to teach a class on hummingbirds for Travis Audubon Society this
summer, and as a result of preparing for that class I have become interested in
discerning the current line of demarcation between regular breeding of our two
Archilochus hummingbirds - Black-chinned and Ruby-throated. I had a hard time
finding Rubythroats in Travis County in June, and I wondered what the situation
is like nearby. I did find RTHU in eastern Bastrop County in June, but it
appears that the western half or two-thirds of Bastrop County is Black-chinned
territory.
So, if you live in Hays, Travis, Williamson, Bell, Gonzales, Milam, Brazos,
Ellis or Dallas Counties, or any counties adjacent to those counties, and you
are pretty sure that you had Ruby-throated Hummers breeding at your place (or
you have photographs of RTHU's in June), I would be interested in hearing from
you.
Regardless of where you live, if you are pretty sure that you had both RTHU's
and BCHU's at your place in the month of June, I would be interested in hearing
from you, especially if you have photographs of both species in the month of
June.
You can reply privately to me or post to the list-serve, as others may be
interested.
Thanks in advance and good birding ya'll,
Byron "Doc" Stone, Austin, Texas
