Brewer's Blackbird Nesting in Cavities
Brewer's Blackbird Nesting in Cavities.
On April 21, 1895, while at Sargents, Cal., a peculiar nesting site of Brewer's Blackbird was noted. A colony of these birds were inhabiting a small live oak grove on a hill. I was surprised to find one nest built in a small cavity on the under side of a rotten oak limb, about ten feet from the ground. The nest was composed largely of Spanish moss and lined with horse hair. It contained two fresh eggs. The cavity was one such as is generally selected by a Sparrow Hawk in which to build.
