body, are lined with white plant down, are all adorned with bits of 

 leaves and bark on the outside, and not one of them has a single 

 lichen on any part of the nest. In addition, they are all very small, 

 with an inside diameter of only about three-quarters of an inch, and 

 all were placed within 5 feet of the ground. They differ markedly 

 from our nests of other hummingbirds of Sinaloa, such as the white- 

 ear, azurecrown, and the violaceous, all these having lichen adorn- 

 ments. The eggs are white, two in number, and at least in the case of 

 the San Lorenzo nest, were laid two days apart." 



Roy W. Quillin (1935) records the finding of a nest of the broad- 

 billed hummingbird in Texas, the only nest so far reported for that 

 State : 



"A nest of this species containing two eggs was found on May 17, 

 1934, at Talley's (Johnson's) Ranch, on the Rio Grande, southwest 

 of Mariscal Mountain, Brewster County, Texas. The nest was on the 

 very bank of the Rio Grande, on a drooping twig in a triple fork of 

 a small willow tree some ten or twelve feet above the ground on a 

 steep bank of the river and almost overhung the water. The nest 

 was composed almost entirely of the down of the willows ornamented 

 on the outside with yellow blooms and tiny mesquite leaves and bound 

 with spider or insect webs. The materials of the nest lashed it firmly 

 to the twigs on which it rested in an upright fork." 



My acquaintance with the broad-billed hummingbird was a brief 

 one in Sabino Canyon, at the southern end of the Santa Catalina 

 Momitains, Ariz. In the rough, rocky bed of the stream flowing 

 through this rugged canyon, Frank Willard and I made a long and 

 laborious search for the nests of this hummingbird. It has been 

 found nesting here in a species of shrub that grows profusely along 

 the rough banks of the stream and among the rocks in its bed. Two 

 or three of the birds dashed by us at different times, in such rapid 

 flight that it seemed as if a whistling bullet had whizzed past us; 

 but we did not succeed in finding a nest ; it was in April, and we were 

 perhaps too early. Mr. Willard had previously found a nest here, 5 

 feet up in a small willow over the water; he told me that O. W. 

 Howard had also found it nesting here. There is a nest from this 

 locality in the P. B. Philipp collection, taken by H. H. Kimball on 

 April 20, 1923, that was placed "in a hackberry bush growing against 

 a small sycamore at the edge of a creek, 4 feet from the water." 



There are three nests in the Thayer collection, taken by W. W. 

 Brown, Jr., near Opodepe, Sonora, Mexico, on May 3, 10, and 13, 

 1905 ; one of these was in an apricot tree and the other two in mes- 

 quites; the construction of these nests compares very closely with 

 the excellent description given above by Mr. Moore.
