most of California and thence northward into Alaska, and goes as far south 
as Paraguay and Brazil in winter. 
Hirundo erythrogaster Bopp. 
Barn SwALlow. 
Mr. Frazar killed two Barn Swallows at Triunfo on April 24, but met with 
no others until August 28, when, on reaching the sea-coast, he found the bird 
at San José del Cabo. During September it was seen almost daily, usually 
in company with Cliff Swallows. Both species fluctuated considerably in 
numbers from time to time, for successive migrating flights were continually 
arriving and passing on, but the Barn Swallows, on the whole, kept increasing 
up to September 27, when they were really abundant. An interval of com- 
parative scarcity followed, but they again became very numerous on October 10, 
the latest date under which the species is mentioned in Mr. Frazar’s notes. 
Although the Barn Swallow is here reported for the first time from the 
Cape Region, it has been seen further to the northward on the Peninsula :— 
at San Quintin, in May, 1881, by Mr. Belding; at San Jorge, in March, 1888, 
by Mr. Bryant; on San Pedro Martir and along the neighboring coast in 
April and May, 1898, by Mr. Anthony. It is very generally distributed, and 
rather common in summer, in California, and breeds as far northward as 
Alaska. Its winter range extends into South America. 
Tachycineta bicolor (VIEILL.). 
TREE SWALLOW. 
Tachycineta bicolor Betpine, Proc. U.S. Nat. Mus., V. 1883, 587 (Oape Region). 
Bryant, Proc. Calif. Acad. Sci., 2d ser., II. 1889, 806 (Cape Region). 
This Swallow was “often seen in winter” in the Cape Region by Mr. 
Belding, in 1881-82, but no one else appears to have met with it in any 
part of Lower California. Mr. Frazar, who looked for it very carefully, but 
vainly, is strongly of the opinion that the record just quoted requires con- 
firmation. There is no apparent reason, however, why the bird should not 
visit Lower California, for it is not uncommon in California proper, and is 
known to migrate as far southward as Guatemala.
