I went down to watch the awesome staging at sunset (from the parking garage
adjacent to the shops and restaurants). After dark I found that indeed,
the crows roost in the trees around Shirlington House (in front, behind,
and west end) and in the trees in the adjacent apartments to the west, Park
Shirlington. I am interested in any additional intelligence anyone might
have about this roost.

There will be a presentation and walking tour about the North Bethesda winter crow roost on December 7 at Pike and Rose (North Bethesda), see the attached flyer for details. We will be joined by Craig Gibson, a national expert on winter crow roosts, and the presentation will be followed by a walking tour as roughly 20,000 crows return to the roost that evening. See the flyer for details, and let us know (scan the QR code) to RSVP.

The winter crow roost near Shirlington is also happening again this year, I
observed it on Nov. 5 and saw birds in large numbers. There was
substantial staging around Shirlington House and along the ridge west of
there, but I could not find the actual roost, despite interviewing various
local residents. If anyone has insights on where these crows actually
spend their winter nights I would love to hear it. The Reagan Airport TDWR
weather radar captures these crows coming and going, I have a lot of
information about where they spend their days (out past Burke to the west,
south to Groveton and beyond), but haven't found the roost area.
FYI there will be a presentation and walking tour about the North Bethesda
roost, and winter crow roosts in general, on December 7, I will post about
that separately.
Thanks for anything anyone can share about this fascinating bit of bird
social behavior.

As for the North Bethesda roost (a separate post), I'd be very interested
in any knowledge folks have about where exactly this roost is overnight (I
found some at Shirlington House Apts. on 31st Street, but far from the
total) and where the crows head to during the days. If you've witnessed
the streams in and out, where, when, roughly how many, direction would be
appreciated.
Thanks again

The winter crow roost at North Bethesda is happening again this year, the
birds are back in large numbers already. I am observing them daily from my
apartment at Pike and Rose (and other locations at times), would again love
to hear from folks who either see them coming and going from the roost, or
have some insights on the exact roost locations. I find many crows again
along Citadel Avenue between Nicholson Lane and Marinelli, but I suspect
there are other locations.
There will be a presentation and walking tour about the roost on December
7, I will post about that separately.
Thanks for anything anyone can share about this fascinating bit of bird
social behavior.
