Audubon’s Michael Sutton was invited by the Santa Lucia Conservancy this week to watch researchers with U.C. Davis ┬áradio tag Tricolored Blackbirds at the Santa Lucia Preserve in the Carmel Valley. As you may know from reading this blog, California’s Tricolored Blackbirds are declining rapidly. Most of the birds live and breed in the Central Valley, but there some coastal populations — and this one at the Santa Lucia Preserve is one of them. The purpose of the radio tagging is to learn more about the habits and movements of these birds when they’re not breeding in their large colonies. Leading the project was U.C. Davis researcher Robert Meese, who also recently took the lead on a statewide survey of the blackbirds. More photos below:

Here’s a photo of a female Tricolored Blackbird — very hard to ID in the field.

    If the reports of Tri-colored blackbirds in Colorado are true, maybe some of the population from the lower latitudes is moving north due to the climate warming. That might also explain why the population decline has been so fast in the Central Valley.
