In Arizona it is apparently rare, according to Mr. Scott, wlio saw small numbers of 

 individuals on tlie lOtli of March, and lie only observed it near Tucson in early sprinsj.'. 

 Mr. Brewster has, however, recoi'ded it as common on the migration in Arizona. 



On the western side of Xorth America, Dr. Elliott Cones believes tliat it breeds 

 anywhere, and it has been taken in all districts apparently. Mr. Brown records it from 

 Vancouver Island. In Washini^ton Countv, accordina- to Mr. Anthonv, it is an abundant 

 summer resident and builds in hollow trees, stubs, and AVoodpeckers' holes. Near Fori 

 Klamath, in Oregon, Mr. Merrill has both found it a plentiful species and breeding ; 

 it arrives about the I^th of April in small flocks, and is al)undant by the middle of the 

 month. 



Dr. Cooper gives the following note in his ' Ornithology of California ' : — 



" This Swallow is to some extent a constant resident in California, a few wintering 

 probably in the extreme southern portion. I first noticed theii" appearance at Stockton 

 on February 22nd, 1863, and was informed by Dr. Holdeu that it does not vary more 

 than three days from that date usually. On February 21st, 1862, I saw the first 

 Swallows near San Diego, probably of this species ; but they have such powers of flight 

 that they might spend the nights of winter a hundred miles from where they feed at 

 midday. When first arriving they fly so high that it is difiicult to distinguish the 

 species. They are the hardiest of all our Swallows, extending their range northward at 

 least to lat. 53°, east of the Ptocky Mountains, and preferring the neighbourhood of tlie 

 coast and mountain-tops in tliis State. On the summit of the coast-range I found them 

 taking the place of the Barn- and Cliff-Swallows, and have seen what I supposed to be this 

 species flying above the summits of the Sierra Nevada as late as Septeml)er 25tli, at an 

 elevation of probably 9000 feet above the sea, migrating towards the south. In tliis 

 State they generally build in the knot-holes of oaks and other trees, but in older settled 

 regions they have been known to jn-efer the advantages of an old building, or the little 

 dwelling you put up for the Martins and Blue-birds. The nest is made entirely of tine 

 grass, lined with feathers, and the eggs, four or five in number, are pure white. TUey 

 commonly raise two broods in a season. Five or six pairs of this species wintered at 

 Santa Cruz, and others about sheltered ponds in tlie vicinity, where I saw tlicin in 

 January, 1866, during the coldest weather of the season. Those at the town roosted in 

 the same knot-holes in the houses where they had i-aised their young, so thai thry were 

 probably constant residents there, and not visitors from the north. ]>ik(' ,ill ilu- 

 Swallows, however, thej^ seemed to depart about September 1st, pi'obal)ly on account of 

 the scarcity of insects during the latter part of the dry season. In Sej)tember. 1S>()5, ] 

 saw a few, probably of this species, near Tulare Lake, where they (hniht'.css found food 

 more abundant."
