They build dur ing March or April, making their nests of twigs, rootlets, moss, feathers, etc., and placing them in forks or on branches of trees (usually conifers) at any height from the ground. The eggs are greenish white, spotted with brown and with lavender shell markings; size .75 x .55.
Range. - Mountain ranges from central Mexico north to Wyoming. A larger variety of the preceding. The eggs will not differ except perhaps a trifle in size.
