Early Migration at Stockton, Cal.
Petrochelidon lunifrons. On the 15th of March I observed a colony of Cliff Swallows around a country barn, which is the earliest record for Central California, except that this and other species of swallows arrived at Murphys on March 15 in 1876 or 1877.
Tyrannus verticalis. First seen March 24, 1900 or two days earlier than any previous record for Stockton. On the 24th only one was seen and two days later I saw two more. No more appeared for several days, a cold spell having apparently checked migration.
The past winter was a very mild one with little or no frost and no sudden changes in temperature. The season is about two weeks earlier than usual but migrants are about on their usual time.
