This shrub growing close to the creek has narrow willow-like leaves and soft white berries on the branches; found along Big Dry Creek, Westminster, CO
Mixed with blackbirds in trees
flock calling from willows and cattails
single bird flying low over marsh and meandering stream, white rump visible
Single bird on the branch of a cottonwood
Growing in the same riparian area along Walnut Creek as P. deltoids. Possibly the hybrid Populus x acuminata?
A. p. domestica x A. p. hybrids.
Two individuals, one observed preening, one observed fishing.
Definitely a cottontail (Sylvilagus sp.); the three candidates for Colorado are Eastern, Mountain, and Desert. And although it's supposedly out of range, the range maps are wrong: there are cottontails ALL OVER the Denver area and have been for at least the last 5 years or so.
But looking more closely at this, I think these photos are of two different individuals (one has rounded ears, one more pointy) and possibly different species. I don't remember what I was thinking when I made the ID (if that was even me)--can anyone help?
Salt Marsh Moth, larval form. Not on host plant, probably looking for a place to pupate.
