72 NEBRASKA ORNITHOLOGISTS' UNION 



418. Phalamoptilus nuttallii (Aud.). — Poor-will. Nesting at the base of the 

 rim rock — four or five pairs to the canon. 



425. Aeronaiites melanoleucus (Baird). — White-throated SAvift. An abun- 

 dant breeder in cracks and crevices of the cliffs. 



459. Contopus borealis (Swains.). — Olive-sided Flycatcher. I secured a 

 specimen of the Olive-sided Flycatcher in the second canon east 

 of Warbonnet on the 14th of June. Breeding- questioned. 



475. Pica pica Jiudsonica (Sab.). — American Magpie. A common breeder 

 in the canon region. 



492. Gyatioccphalus cijanocephalus (Wied). — Piiion Jay. Both adults and 

 young abundant-, but the only breeding evidence secured was a 

 couple of old nests which Mr. Carriker found at the head of 

 Gerlach's Canon. 



521. Loxia curvirostra minor (Brehm). — American Crossbill. Common in 

 the pines in June, but in July feeding- on HeUanthus seeds. Breed- 

 ing doubtful. 



533. Spinus piiius (Wils.) — Pine Siskin. Seen at intervals during July 

 in the pines. Breeding questioned. 



560. Spizella socialis (Wils.). — Chipping Sparrow. An abundant summer 

 resident, nesting in the small pines and cedars. 



567. Junco aikeni Eidgw. — White-winged Junco. The breeding of the 

 White-winged Junco in northwest Nebraska was definitely estab- 

 lished in 1901. Mr. Carriker found a nest containing- young about 

 the first of July, and a little later I saw young birds in the west 

 branch of Warbonnet Caiion — fully two miles west of the first 

 nest found. Old birds were frequently seen in the coolest and 

 dampest portions of the canons among the juniper thickets and 

 quaking aspens. 



581. Melospiza melodia (Wils.). — Song Sparrow. In a canon along Pine 

 Ridge between Crawford and Fort Robinson, on May 24, Prof. 

 Bruner and the writer flushed a Song Sparrow from some 

 Symphoricarpus bushes, which acted in a peculiar manner. A 

 diligent search failed to locate the nest but it is probable that 

 the bird was breeding. 



607. Piranga, lucloviciana (Wils.). — Louisiana Tanager. Common breeder 

 in the pines. 



612. Petrochelidon lunifrons (Say). — Cliff Swallow. Several old nests sup- 

 posed to belong to this species were found on the cliffs. 



615. Tacliyoineta thalassina lepida (Mearns). — Violet-green Swallow. Sev- 

 eral pairs were found breeding among the cliffs, but no sets 

 secured. 



629a. Yireo solitarius plumbens (Coues). — Plumbeous Vireo. Breeding in 

 shaded portions of cations in trees of the mountain maple {Acer 

 (jiabrnm) . 



656. Dendroica auduboni (Towns.). — ^Audubon's Warbler. The breeding 

 range of Audubon's Warbler in northwest Nebraska coincides 

 with the distribution of Pinus ponderosa. The birds usually build 

 their nest in a bunch of pine needles near the end of a branch, 

 where it is concealed very effectually. 



727a. 8itta carolinensis aculeata (Cass.). — Slender-billed Nuthatch. Often 

 seen in the cafions and undoitbtedly breeds.
