Hutton's Vireo

Tilden Botanic Garden, Berkeley, CA

I was at the Botanic Garden with my wife, who was doing an extended bird survey of the Garden with three of her fellow docents. We saw a total of six Hutton's Vireos during the survey, inclduing a pair constructing a nest on an oak tree in the Channel Island section, using lichen plucked from the same tree.
