Bird Field Note Kate Stone 1/31/14

American Tree Sparrows continued to dominate shrubby draw surveys. Though flocks spend a lot of time chattering with each other, they often forage in silence.

The most vegetated areas of Sheep Camp and Tongue Creek saw heavy bird use in both months. Areas along Tongue Creek that lacked tree cover but had dense bitterbrush (circled in green) attracted American Tree Sparrows.

This pile of barbed wire in the Partridge Alley dump hosted a flock of House Sparrows and a single Song Sparrow. During our draw surveys, Jeff and Mike removed the pile to tidy the dump area. The sparrows promptly moved to a newly stacked pile of wooden pallets.

pallets. Sheets of ice coated the bottom and sides of the draws, making for treacherous surveys.

This year we are focusing winter point counts on the low-elevation areas undergoing major restoration treatments. We will visit these locations three times over the winter to look at how use changes through the season. Right now the abundance of bare ground and scattered seed attracts flocks of Horned Larks, with a few Snow Buntings and Lapland Longspurs mixed in.

Small mammals also like winter wheat seed. Melting snow exposed this cache, likely hidden by a deer mouse.

in. Waxwings gather at the river’s edge to take small sips of water. Warm weather has prompted several insect hatches, offering the waxwings fly-catching opportunities.

Thousands of Mallards gather in the corn stubble. Northern Harriers, Prairie Falcons, and Merlins continue to hunt over this field.

We saw fewer species of raptors in January than in December. We saw more Rough-legged Hawks than any other species. Recently we have had little snow and relatively mild weather. Some people believe that Red-tailed Hawks dominate Rough-legged Hawks, so if snow accumulates and hunting conditions become more challenging, we may see fewer Roughleggeds in February. Calving began this month, and we expect to see congregations of Bald Eagles around calving fields.

A dark Rough-legged Hawk gets a different perspective on a roadside rodent.

A pair of Bald Eagles sit together on the floodplain.

This Bald Eagle sat in the front yard of a private residence and appeared injured. When we returned 20 minutes later to capture it, we could not find it. Hopefully the injury was minor.
