1. FALCO POLYAGRUS, Cassin, (p. 12.) 1 —Great-footed Hawk. 
8503. Camp on Little Colorado, 1853-4. (38.) Kennerly & Mollhausen. 
This beautiful hawk we observed while encamped on the Little Colorado river. When seen 
he was busily engaged in seeking his prey among the hushes that grew along the river. With 
difficulty the specimen was procured, and very fortunately also, as we did not see it again. 
2. TINNUNCULUS SPARVERIUS, V i e i 11, (p. 14.)—Sparrow Hawk. 
8507. Camp 105, New Mexico, January 23, 1854. Kennerly & Mollhausen. 
This beautiful little hawk we saw first in the vicinity of the Aztec mountains. It confined 
itself to the open valleys or among the scattering cedars on the hill sides. We found it some¬ 
what difficult to procure a specimen on account of its shyness, although we saw it frequently 
from thence to the Pacific. 
3. BUTEO MONTANUS, Nutt a 11, (p. 26.)—Western Red-tail. 
8533. Camp 149, New Mexico, March 16, 1854. (185.)—8549. Camp 114, New Mexico, 
February 6, 1854. (71.) Kennerly & Mollhausen. 
This species of hawk was by far the most abundant that we observed from the Rocky 
mountains to the Pacific ocean. Wherever we found smaller birds we were sure to find this, 
their untiring and watchful enemy. One specimen that I obtained had the proventriculus 
filled with mice, small birds, and lizards. 
4. BUTEO ELEGANS, Cassin, (p. 28.)—Western Red-shoulder. 
8524. Camp on Little Colorado, New Mexico, November 17, 1853. (32.) Kennerly and 
Mollhausen. 
5. ARCHIBUTEO LAGOPUS, Gray, (p. 32 )—Rough-legged Hawk. 
8546. Near Zuni, New Mexico, November 9, 1853. Kennerly & Mollhausen. 
We found this large and beautiful hawk quite abundant in the vicinity of the Pueblo of Zuni. 
Here it confined itself to the neighborhood of the stream, watching eagerly for ducks, which 
seemed to be its favorite prey. We did not observe it often after leaving this village. 
6. CIRCUS HUDSONIUS, Vie ill, (p. 38.)—Marsh Hawk. 
6860. Fort Conrad, New Mexico, October, 1853. Dr. Kennerly. 
We found this bird throughout Texas and New Mexico, wherever we found a marsh. When
