Swallow was observed by him "only on North Mountain, where one or two pairs were 

 nestino- in a barn.'' Mr. Coombs, in his notes from St. Mary's, Louisiana, observes that 

 it is a spring and autumn migrant, remaining for a longer period in the latter season. 

 He noticed flis:hts as late as the 25th of November. 



In the Caloosahatchie region of Plorida Mr. "W. C. D. Scott states that the present 

 species is not only a migrant, but that enough remain during the winter to allow the 

 species to be regarded as resident, and not casual, at that season. The same careful 

 observer found this Swallow on the Tortugas off Western Florida, but it was not 

 common. A small flock made its appearance on the 29th of March, and remained near 

 by all that day and part of the next. There were in all about a dozen birds, two of 

 which were procured. 



Mr. Attwater records it as a common migrant near San Antonio, in Texas. 



According to Mr. Streator, this species is a common summer resident in the coast- 

 region of British Columbia, and breeds there. Mr. John Fannin found that it was more 

 abundant east of the Cascades. 



Mr. Belding gives some additional notes on this species in his paper on the birds 

 of the Pacific District : — At San Diego he says that it is " of occasional occurrence in 

 winter; not seen at Campo and 60 miles south in May, 1884. Perhaps none breed so far 

 south as San Diego, where it was abundant in Pebruary, but not seen after the 1st of 

 April." 



At Santa Cruz, San Jose, and Marysville, it is an abundant summer resident. Near 

 Stockton on the 5th and 6th December he noticed about a hundred specimens. He also 

 saw on December 5, 1878, a large flock. On January 18, 1855, he saw hundreds or 

 thousands in a drive of six miles in the country. The next day being densely foggy, 

 none were seen. It is a very common summer resident of Central California, more 

 especially in the valleys and foot-hills, nesting about buildings as well as in knot-holes 

 of trees in the country. He saw a pair carrying grass into a knot-hole at Stockton as 

 early as March 25, 1879. 



Mr. Belding's dates of the arrival of this Swallow, derived from many sources, show 

 that it has been noticed in California as early as the 18th of January, and many instances 

 are given of its arrival in Pebruary. In British Columbia its arrival is later, as 

 Mr. Pannin noticed its arrival on the 13th of March, while Mr. Anthony gives the 4th 

 of April as its arrival in Oregon. 



Dr. C. Hart Merriam's account of the Death Valley Expedition contains the following 

 note : — " White-bellied Swallows were seen in a few places during migration. Several 

 were seen at Ash Meadows, Nevada, March 12, and a number near the Colorado Eiver, 

 March 10-13. At Purnace Creek, Death Valley, it was common about the reservoir, 

 March 23-24, and again in the middle of April. A few were seen in Johnson Canon in the 

 Panamint Ilange, April 4, and Mr, Nelson observed stragglers at the head of Willow 

 Creek, in the same range, the last of May."
