BAHAMA SWALLOW 371 



I can find nothing in the report of this expedition, or elsewhere, 

 to indicate that the habits of this subspecies are in any way different 

 from those of the other desert-loving races. 



OTOCORIS ALPESTRIS LEUCANSIPTILA Oberholser 



SONORA HORNED LARK 



HABITS 



From extreme southern Nevada southward along the Colorado River 

 in western Arizona and extreme southeastern California and into 

 northeastern Lower California, we find this extremely pale desert 

 race. In describing it, Dr. Oberholser (1902) says: "This new race 

 is the palest of all the American horned larks, not excepting pallida 

 itself, from which form it further differs in lacking much of the cin- 

 iiamomeous tinge of the upper parts, particularly on the cervix and 

 bend of the wing. Other characters distinguishing leucansiptila from 

 actia and ammophiJa are the more uniform upper surface and the 

 much more pinkish shade of the cervix, upper tail-caverts and bend 

 of wing; from occidentalism the decidedly smaller size; from adusta^ 

 the conspicuously less reddish upper surface ; from lev/colaema^ reduced 

 size and more uniform upper parts." 



I can find nothing published on its habits, which probably are sim- 

 ilar to those of the other desert races in neighboring regions. 



Family HIRUNDINIDAE: Swallows 



CALUCHELIDON CYANEOVIRIDIS Bryant 



BAHAMA SWALLOW 



HABITS 



This lovely bird, with its velvety green crown and back, its steely 

 blue wings, pure white under parts, and long forked tail, is one of our 

 most beautiful and graceful swallows. Except for occasional w^ander- 

 ings it seems to be confined mainly to the Bahama Islands, but recent 

 collectors do not seem to find it very common even there. Dr. Henry 

 Biyant (1859), who described and named this swallow, says: "I saw 

 them during the whole of my stay at Nassau [Jan. 20 to May 14], 

 but only on the first mile of the road leading to the west end of the 

 island. They were so abundant there that thirty or forty could be 

 seen at almost all times." 



According to C. J. Maynard (1896), it was not so abundant at 

 the time of his visit as Dr. Bryant's account would indicate, for he 

 says : "I do not think that the entire number inhabiting the island of 

 New Providence, even in June, amounted to over fifty individuals."
