Early Nesting of the Pasadena Thrasher
Early Nesting of the Pasadena Thrasher.
On the 15th of last month, (December '99,) Dr. Fenyes and myself, while hunting over a brush-covered wash near Azusa, were surprised to find a nest of this species (Harporhynchus redivivus pasadenensis). It was in no ways peculiar, except as to the date, being built two and one-half feet above the ground in a black-sage bush. One of the birds was sitting closely and the other singing from its perch at the top of a bush not far off. The nest contained three eggs in which incubation was well begun. The thrashers are always in full song soon after their single annual moult which occurs in August, but they do not ordinarily breed before March and April, though we have one county record for January 27 (Birds of the Pacific Slope of Los Angeles County).
