Cobirds:
Large concentrations of (migratory) common nighthawks were seen
foraging in Louisville tonight; perhaps a hundred, maybe more. Low
pressure system is causing insects to drop, so the nighthawks follow them,
which makes for interesting viewing as they glide and flap, up and down
suburban streets. Largest concentrations seem to be near Fireside
Elementary School and Heritage Park.
At Walden / Sawhills, there were large flocks of barn swallows,
tree swallows, violet green swallows, and rough winged swallows - hundreds
coming through on migration. Many are still feeding young.
Walden / Sawhills is nearly dried up, with many of the ponds
completely dry, and others only at 1/4 capacity. Nonetheless there are
still good birds about, including:
Yellow warblers - feeding young
Warbling vireos - lots
Western wood peewees - lots
Eastern kingbirds - still feeding young
Great blue herons - I counted over 15 dispersed
American white pelican - 6
Killdeers - numbers increasing
American avocets - 9
Spotted sandpiper - 1
House wrens - lots of family groups with immatures
EASTERN PHOEBE - still at the Heatherwood Trail as of Tuesday this week,
where a footbridge extends over an outlet
Belted kingfisher - 2
Swainson's hawks - 2
Red tailed hawks - 2
Mourning doves - 12
Red winged blackbirds - 11 - numbers rapidly decreasing
Song sparrow - 2
Common yellowthroat - 1 still singing
And others....
Another note: In Gunbarrel on Spine Road near the General Electric
corporate building - a group of 12 bushtits foraging in an isolated locust
tree on a lawn. A bit unusual.
Wildflowers above 11,000 feet hit their peak about a week ago, but are
still fairly good for viewing. Some of the better trails for photography
were the 4th of July Trail, the Heart Lake Trail, the Arapahoe Peak and
Arapahoe Glacier Trail.
