All: Some observations over the last few days: Waves of duck species are coming through in good numbers, especially at Plaster Reservoir: scaup, ring necked ducks, widgeon, canvasback, redheads, mallards, gadwall, some hooded mergansers, common goldeneye, and American coots.
Canada and cackling geese numbers are decreasing. First cormorant seen at Plaster Res. Two American White Pelicans at Plaster - both adults - reported by others already. Great blue heron numbers increasing. Marsh Wren singing vigorously at Cascade Lake in reed beds, Anthem Neighborhood. Say's Phoebe's are back in good numbers but seem late this year. Eared Grebe seen at Plaster Res. Red tailed hawks nesting in various locations Great horned owls - females are now sitting higher on nest sites, indicating chicks have hatched (Broomfield, Thornton, Westminster, Boulder, and Longmont) American robin numbers are increasing, but numbers are down from last year - territorial fights have started. Spotted towhee numbers are increasing - males are singing Killdeer numbers increasing. White crowned sparrows and juncos are still present at lower elevations. First Common Grackle seen near Cascade Lake, Broomfield. Large waves of male red-winged blackbirds are still coming through.
The Bald Eagles are Stearns Lake (Boulder County) are still on the nest site down the main dirt road south of the parking lot. Signs are up that the trail is closed, as well as the road to thru traffic. But you can still walk down the road to see them - the sign is not explicit enough to say if this is illegal or not (?). The eagles built a nest in a big cottonwood, then stopped and built a 2nd nest above the first nest. Why the eagles did this is unknown.
Western Painted Turtles are out already - way early!
Pasqueflowers, springs beauties, and Oregon grape are starting to bloom in the foothills. These blooms are a timed indicator that spotted towhees have started singing.
I will try to post some "hot spots" for new birders later.
Happy spring! John T (Tumasonis), Broomfield CO "I'm not a real birder. I only pretend to be one on CoBirds."
