The Western Lark Sparrow and the Dwarf Cowbird
Online Full Text
There seem to be but few records of the Western Lark Sparrow (Chondestes grammacus strigatus) being a victim of the Dwarf Cowbird (Molothrus ater obscurus). It was thus interesting for me to see a nest in a local orange grove on May 31, 1934, which had suffered from this pest. The nest had been located a couple of days earlier by Oscar Clark but had been deserted when I saw it, although it contained one perfectly fresh egg of each species.
Our fellow member, Mr. J. Stuart Rowley, has authorized me to state that he collected a set of five eggs of the Western Lark Sparrow with one egg of the Dwarf Cowbird on May 6, 1934, at Gorman, Los Angeles County, California.
