Alan et al.,
At this time of year I occasionally see presumed hatch-year male Red-wingeds
that are really dark like this bird. Unless the photo is misrepresenting the
colors, I would call this a Red-winged on the basis of the buffy and even
slightly golden tones of the supercilium and the lighter areas on the
underparts. The other feature that I think points to Red-winged is pattern of
streaking below. Red-wingeds seem to be more uniform in their streaking from
breast to belly, whereas female type Tricoloreds are paler and heavily streaked
on the breast while looking more solidly dark and less streaked (if streaked at
all) on the lower breast and belly. Overall, this bird does not seem 'cold' and
ashy enough for Tricolored. It looks warm and brown, rather than cold and gray.

Subject: [obol] ankeny, baskett, odd blackbird
Tristen Hynes and I attended a special event at Ankeny today and then did some
birding. Highlights at Pintail Marsh included a late ROUGH-winged Swallow and
two White-fronted Geese. Plenty of Cackling mixed in with Canadas.
At Coville narrows at Baskett there is now some water. Perhaps a thousand
swallows, 4:1 Barn:VG. We also saw a female blackbird of which I obtained one
photo. Not sure whether it is a very dark redwing or a splotchy Tricolored.
We also saw a rather large swift with Chimney-like wings that flew around
silently with a few Vaux and a thousand swallows then went south.
