the light edging on the wing coverts and secondaries much broader and more 
or less tinged with yellowish. Some of the males show a few black feathers, 
possibly of the coming autumnal plumage, on the breast and throat. 
General remarks : — Upon comparing spring specimens in full plumage from 
Lower California with others from Arizona and northwestern Mexico, I find two 
slight differences which seem to be correlated with geographical distribution. 
The yellow of the rump and under parts in the male of the Lower Catifornia 
bird is lemon, whereas in all my Arizona skins it is gamboge. The posterior 
outline of the black on the breast is also more clearly defined in the Lower 
California specimens than in those from Arizona. In the latter many of the 
posterior black feathers are tipped with yellow. Mexican examples appear to 
be intermediate in both these respects between the Arizona and the Lower 
California specimens. I do not find any constant differences in size or propor- 
tions between the birds from the several regions just mentioned. There is per- 
haps a greater tendency to black on the head, throat, etc., in the female from 
Lower California than in that from Mexico and Arizona, for, as already men- 
tioned, all the spring females before me which wholly lack the black are from 
Arizona or western Mexico. 
In the Cape Region Scott’s Oriole is resident, but perhaps somewhat more 
numerously represented in summer than in winter. At the former season it is 
very generally distributed, occurring almost everywhere from the lowlands along 
the coast to the summits of the higher mountains. It shows a marked prefer- 
ence, however, for dry, barren country such as that about Triunfo, where Mr. 
Frazar met with it in the greatest numbers. On July 8 at Pierce’s Ranch he 
found a nest “ containing three young, nearly large enough to fly. This nest 
was made of the yellow fibre of palm leaves, and was lined with a few long, 
black horse-hairs. It was placed among the densest foliage of a fig-tree at a 
eight of about eight feet, and rested on a few small twigs, but seemed to be 
fastened only to some twigs above, from which if was suspended. It was not 
deep, for the heads of the young appeared above the upper edge.” 
Scott’s Oriole has been found at various places in the central and northern 
portions of the Peninsula as well as near San Diego and Los Angeles, California, 
the locality last named being perhaps the most northern one to which it ever 
extends its summer range. In the mountain portions of Lower California it is 
said by Mr. Bryant, on the authority of Mr. Anthony, ‘‘ to prefer the low hills 
near the coast south of San Quintin, where it nests in the thorny branches of 
the candlewood (Fouquiera columnaris ).” 
Scott’s Oriole also breeds in southern Arizona, New Mexico, and western 
Texas. “In winter it passes southwards as far as Central Mexico in the States 
of Puebla and Vera Cruz; and Sumichrast includes it amongst the birds of the 
temperate and alpine regions of the latter State. It breeds, he says, in the 
temperate region, and is found as high as between 5,000 and 6,000 feet above 
the sea in the neighborhood of Orizaba, and at even higher altitudes in the 
plateau.’ 1
