THE White-throated Swift is an 
abundant resident of Southern Cali- 
fornia, and may 
be seen in num- 
bers in the vicin- 
ity of the Old 
Mission at San 
Juan Capistrano, as well as in Los 
Angeles County and other localities. Its 
nesting site is the most inaccessible cliff 
of the regions where it is resident ; con- 
sequently only a few nests have been in- 
vestigated. The best account of one is 
given by Mr. W. B. Judson, of Los 
Angeles, where the nest was found. “It 
was situated about eighty feet from the 
top of a cliffand one hundred and twenty- 
five feet from the ground, in a cave about 
seven feet high, ten feet wide, and ex- 
tending some seven feet in the face of 
the cliff. The nest was placed in a small 
hole in the roof of the cave, —
