Nests of MacGillivray's Warblers
- Dave and others on the Eel River field trip wondered
whether MacGillivray's Warblers are ground nesters.
No, is the answer I found in a couple of old bird books.
MacGillivray's nests are usually 1 to 4 feet off the
ground and are fairly loose cups of grasses held in dense
patches of shrubs like blackberries or poison oak. The
clutches are usually 4 speckled, white eggs.
The first nest was discovered on 17 May, 1897, in Sonoma.
