Late Nesting of the Olive-Sided Flycatcher in the San Gabriel Mountains, California
Late Nesting of the Olive-sided Flycatcher in the San Gabriel Mountains, California
Mr. W. D. LaNiece of San Bernardino, brought to me on July 8, 1933, a fresh set of three eggs, together with the nest, of the Olive-sided Flycatcher (Nuttallornis mesoleucus). He had collected this on the previous day in the San Gabriel Mountains, near Wrightwood, about 6000 feet elevation, San Bernardino County, California.
The nest was far out on a downward sloping branch of a large yellow pine and about forty feet, from the ground. The location had been discovered twelve days earlier by watching the birds go to the nesting site, but even the completed structure could not be seen from the ground. One of the eggs was perforated in removing it from the nest, the weights, in grams, of the other two were 3.93 and 3.69. This is the latest nesting date which I have ever seen recorded.
