BREWSTER: BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 125 
its anterior corner backwards about half an inch; under parts grayish white, 
bordered on the sides of the throat and breast with brownish drab, which also 
forms a narrow and rather obscure band across the breast; wings and tail as in 
the adult, but with the greater covert tipped, and some of the middle and lesser 
coverts tinged, with drab. Bill, tarsi, and feet black. 
Autumnal plumage: — This differs only slightly, if at all, from the nuptial 
plumage. Indeed, the birds wkich I take to be adult are practically insepar- 
able from unworn spring specimens. Others, probably young, have the blue 
paler, the brown of the scapulars and back duller or more ashy. 
This, the only Jay known to inhabit the Cape Region, is very common and 
generally distributed there, being found almost everywhere from the sea-coast 
to the tops of the highest mountains. About La Paz it nestsin March, but the 
birds seen by Mr. Frazar on the Sierra de la Laguna in May and early June were 
in flocks and showed no signs of having bred that season or of being about to 
breed. They probably leave the mountains before the beginning of winter 
and seek more sheltered haunts in the valleys and foothills at lower eleva- 
tions, for Mr. Frazar did not find a single individual on the Sierra de la Laguna 
during his second visit, in the latter part of November, 1887. 
Mr. Bryant found a nest of this Jay “a few miles southward from San 
Ignacio on April 12, 1889. The nest was built about three metres high in a 
green acacia near the trail. The female was sitting, and did not fly until 
preparations for climbing the tree had commenced. The nest was in quite an 
exposed situation amongst scant twigs on a horizontal branch. It is composed 
of small loosely laid dry twigs, and a shallow receptacle lined with fibre and 
horsehair. 
“ The eggs, three in number (set No. 89y, coll. of W. E. B.), contained small 
embryos. They are more finely spotted than some similar jay’s eggs, with 
shell spots of pale lilac-gray and surface spots of pale olive-green. The ground 
color is dull, pale glaucous green. They measure 27.5 X 20.5; 27.5 X 21; 
27 X 21 millimetres.” 
Xantus’s Jay is confined to Lower California. It was first seen by M.. 
Bryant “among the mangroves of Magdalena Island, and along the mangrove- 
bordered estero to San Jorge, and northward as far as lat. 28°.” On San Pedro 
Martir mountain it is replaced by obscura, a race doubtfully distinct from calz- 
fornica. The latter bird is said to occur still further to the northward on the 
Peninsula, “about Ensenada and to the eastward.” }
