I8S6.J Scott oti the Birds of Arizona. 4"^ I 



In 1S84 I did not meet with the birds in the Catalinas till late in Julj, 

 and then only sparingly. But in 1SS5, in the same locality, the birds 

 were very common by April 5, particularly the males, in the most gor- 

 geous plumage. The absence of" adult females for the next six weeks was 

 very noticeable. I think I took only three, though the males were com- 

 mon all the time. About the 20th of May young birds of the year began 

 to be abundant, and adult birds of either sex were difficult to find. The 

 young birds were common all through June; I sould often count twenty 

 near my house, but after June i I was unable to get any adult birds of 

 either sex. I do not think the birds bred in the Catalinas, but think that 

 probably they did breed in numbers on the San Pedro River. 



100. Trochilus anna. Anna's Hummingbird. — The only time that I 

 have met with this species was in the Catalina Mountains at an altitude of 

 5000 feet, when on October i, 18S3, I took a male bird, young of the year 

 (No. 420 of my collection). Mr. Brown has no records of its occurrence 

 about Tucson at any season, and I am disposed to regard it as a rare spe- 

 cies throughout the area under consideration. 



loi. Trochilus platycercus. Broad-tailed Hummingbird. — Rather 

 common spring and fall migrant, and a few remain during the summer, 

 doubtless breeding in the higher altitudes of the Catalinas. All of the 

 birds collected by me in the region about my house, even in spring, are 

 either females or males that have not assumed full plumage. The birds 

 seem to be most common in the Catalinas from August 20 to September 

 10, and a few remain till October i. They arrive here in the spring 

 about April 1. The species doubtless occurs, at least during the migra- 

 tions, throughout the entire area, though my only notes are from the Cat- 

 alinas. 



102. Trochilus rufus. Rufous Hummingbird. — Not common in 

 spring, but young birds of the year begin to appear about the middle of 

 July, and by August 1 are common. In August and September they are 

 very abundant, feeding on thistles and a kind of scarlet flower very similar 

 to the salvia or scarlet sage. It is no uncommon sight at such places 

 and times to see from twenty to fifty of the birds at once. They leave 

 early in October. I have taken very few adult birds of this species at any 

 season, and only one male in full plumage in a large series. These ob- 

 servations are based on data accumulated in the Catalina Mountains : alti- 

 tude 4000 to 6000 feet. There can be little doubt that the species breeds, 

 perhaps commonly, at the higher altitudes in these mountains. 



103. Trochilus alleni. Allen's Hummingbird. — The only record 

 that I am aware of, of this species from the territory of Arizona, is an 

 adult male (No. 589) taken in the Catalina Mountains at an altitude of 

 4500 feet, July 23, 18S4, and now in the collection of the American Muse- 

 um of Natural History at Central Park, New York City. 



104. Trochilus calliope. Calliope Hummingbird. — This species 

 seems to be of uncommon occurrence in the area under consideration. I 

 have only two records of its capture, both in the Catalina Mountains, at 

 an altitude of 5000 feet. These are both females, apparently adult (No.
