line. Mr. Scott, as stated in his paper on the ornithology of the Twin Lakes, found it 

 abundant in localities, but not generally distributed. Mr. Beckham also states that he 

 observed the species but once at Pueblo, when a dozen or more were seen on the 10th 

 of June. In their paper on the birds of Colorado, Messrs. Allen and BrcAvster remark : — 



" First seen May 4th. A considerable number observed on the 14th, and at frequent 

 intervals later. In July and iVugust large numbers w'ei^e seen near West Monument 

 Creek, where they outnumbered all the other Swallows." 



In Utah, as in Arizona and New Mexico, Mr. Henshaw states that this Swallow 

 inhabits the higher regions, being abundant in all suitable localities, and preferring the 

 open spaces or edges of the piuaries and groves of oaks, where it breeds in old Wood- 

 pecker-holes. 



Mr. Eidgway has recorded the species as abundant on the main island in Pyramid 

 Lake, Nevada, in the month of May, and in July he saw it again among the limestone 

 walls of the eastern canons of the Ruby Mountains, where it was also nesting. 



Mr. Anthony, in his paper on the birds of Washington County, Oregon, says that 

 it is "a very common migrant, a fcAV remaining to breed, nesting in colonies in hollow 

 stubs." Dr. Merrill did uot observe it himself at Fort Klamath, but says that it must 

 occur there ; he found it, however, very common at the outlet of Diamond Lake early 

 in August. 



The observations on the species in California have been numerous and varied. The 

 following note is given by Messrs. Baird, Brewer, and Eidgway, from the writings of 

 Dr. Hepburn, a very Avell-known observer: — "This Swallow has quite an extensive 

 range along the Pacific coast, but it is restricted as to the localities it inhabits. At the 

 Pulgas Handle, near San Francisco, it is even more common than T. bicolor, while a 

 few miles from thence uot one is to be seen. He has also seen it on the bank of the 

 Fresno, near its junction, with the San Joaquin River, and again in the Yosemite Valley, 

 without meeting with a single specimen in the inteiwening country. About Victoria 

 this w-as the prevailing species. These Swallows, as far as Mr. Hepburn observed, 

 always build in holes of trees. Their nest, he states, is formed of a few fine dry stems 

 of grass, placed at the bottom of the hole, covered over Avith a thick mass of feathers. 

 These birds have two broods in a season. In 1861 he noted their arrival in San Mateo 

 County on the 28th of March." Dr. Cooper says : — " I have not observed this species 

 Avest of the Coast Range, except when emigrating. They appeared at Santa Cruz in 

 1866, on March 19th, and a large flock, with a few Chcutura, stopped for a few hours on 

 their way soutliward, October 5th, Avhich dates are j)robably about the usual ones for 

 their migrations." 



Mr. Cliarles ToAvnseud, in his account of the birds of Northern California, says that 

 " the Violet-green Swallow Avas often seen flvin": over the almost inaccessible limestone 

 rocks Avliich crowned the high ridge opposite the United States Fishery." Here he 

 procured his first and only specimen on July 4, 1883. 



Mr. L. Belding, in his paper on the Birds of Central California, says that it was first
