Matt: At the Utley place in Bastrop Co. after 30 years watching, the
Ruby-throats depart by Sept 26-29 including hatch year birds. If a hummer
shows up after that it is always of interest. Have not had enough BCs
there to know about their late dates and have not been in Cedar Park long
enough to have that figured out.

Subject: [texbirds] Re: Black-chinned & Ruby throat overlap
An angle on this comment that always interests me is the departures in
fall of Black-chinned, since I see so many unlikely reports at a point when
99% of them are gone. With all the appropriate caveats, like outliers not
following the rules, etc, BCHU migrate early. Adults where I live (north of
San Antonio) start peeling away in early to mid August. My 4-6 ad males are
usually down to 1 (or 2 if lucky) by Aug 15 and I have never had an ad male
past August at my house. By early Sept, I am scrutinizing Archilochus to
find an im BCHU. Im males are around regularly into Sept, in and around San
Antonio (but outnumbered by RTHU) sometimes to or just past mid-Sept. Im
males are easy to ID, given their partial gorgets, so it is no surprise
that most records at that season are im males. And, no doubt an outlier
will be available to break the rule, i.e. an adult male basking in Labor
Day sun, but there is no doubt the majority of adult males are long gone by
then.
So in this area, any BC after mid Sept is worthy of scrutiny. Yes, we get
the odd one even in winter; and, there are more lingering further south,
west, and on the Gulf; but for this area and points further north and east,
cautious identifications of these hummingbirds would be helpful in
providing a better delineation of departure dates.

have âlostâ overnight.
I live in Copperas Cove (Coryell County) (31 06â44.09â N 97

and have been observing both species in my back yard every year,
without fail, since 2007.
They usually arrive in late March, Black-chinned males show, up first
and usually depart in late September or early October. My observation
is that they return south just a day or two before a cold front comes in.
These shots are on the same day at the same feeder. Iâve never seen
both species feeding at the same feeder at the same time. Of course,
I cannot readily ID the females, so I could be wrong on that.
