Swainson's hawk

The threatened Swainson’s hawk will lose 10 acres of foraging habitat with the project, and the tricolored blackbird relies on nearby areas for food and its nesting materials.

A River Partners analysis of the property found species including riparian woodrat, Swainson’s hawk, least Bell’s vireo, yellow warbler, sandhill crane and “an entire suite of neotropical migratory songbirds.”

As Rentner walked through the forest, a Swainson’s hawk circled overhead.

“We’ve also seen a number of unusual Western species in Brooklyn, including Townsend’s warbler and Swainson’s hawk.”

Poison also killed a golden eagle, a Swainson’s hawk, 14 ravens, 17 magpies, one coyote and several small mammals.
