All:
A hike up Bear Creek and into Bear Creek Canyon, Boulder Colorado. Start from Bear Mountain Drive up Bear Canyon Trail and back down again. Here's what I observed:
Turkey Vulture: 4 soaring
Golden Eagle - 2 - being pummeled by a raven
Red Tailed Hawk - 1
Wild Turkey - 1, calls
Mourning Dove - a few
White Throated Swift - a few, flying, calls
Broad Tailed Hummingbird - lots - all males, some doing display flights.
Downy Woodpecker - 1
Northern Flicker - a couple
Blue Jay - a few
Steller's Jay - a few
Black Billed Magpie - about a dozen
Common Raven - attacking golden eagles
Violet Green Swallow - flying, calls
Black Capped Chickadee - a few
White Breasted Nuthatch - only one
Red Breasted Nuthatch - a few, calls
House Wren - numerous - songs, chases
Blue Gray Gnatcatcher - only one
Yellow Warbler - 1
Orange Crowned Warbler - 1
Audubon's Warbler - several, singing
Myrtle Warbler - several near the parking area
Virginia's Warbler - one singing and foraging
MacGillivray's Warbler - only one
Yellow Breasted Chat - only one, but good looks
Western Tanager - one male, down low near parking area

Lazuli Bunting - about 6 males - songs, chases, good looks
Common Grackle - numerous down low near parking area
Brown Headed Cowbird - a few
House Finch - numerous down low
American Goldfinch - a few
And:
Mule Deer - 6
Pine Squirrel - 1
And:
Wildflowers in bloom: Wild Iris, Biscuitroot, Desert Parsley, Meadow Salsify, Oregon Grape, Sand Lily, Golden Currant, Dandelion, Death Camas, Golden Banner, Cranesbill, Mustard ssp, (note: foothills have dozens of pasqueflowers and thousands of spring beauties blooming in ponderosa woodlands now);
Wild plum blooms are late - they signal the arrival of chats, grosbeaks, catbirds, and warblers.
Note: if going to explore this riparian area it is suggested you go on a weekday, early morning. The crowds on Saturdays and Sundays make birding and wildlife viewing problematic.
