In May, 1879, I took nine sets of the eggs of Maximilian’s Jay 
in Colorado. Their nests were all found within from five to nine 
miles east and southeast of Fort Garland. This region lies along 
the western base of the Sangre de Christo Mountains, is broken 
by hills and spurs from the main range, and has an elevation of 
about 9000 ■ feet. The nests were all in high, open situations, 
two of them well up the steep mountain sides, and none in valleys 
or thick timber. All were in small pinon pines from five to ten 
feet up, out some distance from the body of the tree, and not 
particularly well-concealed. They are large, coarse, and deepfy 
hollowed structures, much alike, being made mostly of grayish 
shreds of some fibrous plant, or bark, which breaks up into a 
mass of hair-like fibres, these forming the lining, while some 
weeds and grass are worked into the general fabric. I did not 
measure any of them before removal, and afterwards accurate 
measurement could not be made, as, being loosely constructed, 
they spread and flattened. They must have been about as deep 
as wide, deep enough to receive the whole body of the bird, only 
part of the head and tail showing above the edge. The birds are 
close sitters, several not leaving till the nest was shaken, and I 
could have caught some of them with my hand. On being driven 
from the nest, they woidd alight on an adjoining limb, and, with
