No rarities today but a nice total of 42 species and interesting behaviors.
Highlights:
Cassin's Vireo (1)
Plumbeous Vireo (1) in the same tree as the Cassin's, with the gray one seeming
mildly annoyed at the green one
Black-headed Grosbeak (1)
Western Tanager (1) FOY for me in northern CO
Broad-tailed Hummingbirds (two different instances of 2013 nest re-use going on
at present, with one of these nests going all the way back to 2010)
Swainson's Thrush (at least 3)
Great Horned Owl (2 babies out of the nest for the first time I've seen this
year - it was reported to me that a third baby fell out of the nest and was
killed. Gawkers (bubophiles?) with big cameras beginning to show up as
predictably as peony blooms.)
Empid sp. (suspect something other than Dusky/Least, poor looks)
Downy Woodpecker preying on Golden Oak Scale in Bur Oak
Mini-flock of 4 Red-tailed Hawks cavorting high in the sky ("menage a quatre"?)
White-crowned Sparrow (1 pale-lored, getting late)
European Starlings heard mimicking both Western Wood-Pewee and Solitary
Sandpiper
In one medium-sized Bur Oak tree were 7 Fox Squirrels, all out at the ends of
the branches chowing down on the flowers of this tree. It reminded me of my
chocolate chip cookie-loving boys when they were kids always trying to get at
the dough, and their mother saying something to the effect, "Eat all the dough
and there won't be any cookies". Presumably oak flowers contain at least most
of the raw ingredients of next autumn's acorns.
