May, 1913 THE ROCKY MOUNTAIN PINE GROSBEAK IN UTAH 107 there but a moment it dropped to a bare spot nearby, flew back up to the stable roof, then away to some large aspens, carrying in its bill a sinall twig. That this bird was a female Pine Grosbeak I felt sure, although the distance was too great to be positive. Not allowing my eyes to wander from her, I reached for my binoculars as she hopped from branch to branch with that careless unconcern, in ?vhich art these birds are quite proficient. Presently she flew up the mountain side to a large, lone fir standing in a body of small aspens, and [ raised my glass- es just in time to see that she had alighted within a foot or so of what seemed to be an already well-formed nest. After placing her material, she returned to the stable, then dropped to the bare spot in search of more nest material, as before, continuing to and from her nest in this inanner for more than an hour. Then to make myself doubly certain, I made my way up the mountain, and upon climbing the tree, found a nest whose lining was partially completed. The nest was situat- ed in a rather heavy clump of boughs, fourteen feet out on a horizontal brauch, and some twenty-five feet from the ground. The fe- male was not at the nest at the time I COlnmenced to climb the tree, but presently returned, alighting within two ' ' feet of me, to immediately fix- ' away again, and was seen no more this day.

I found the female Grosbeak gathering " ?1 ' nest inaterial, I heard, calling at regular intervals, a male Grosbeak; but no bird had yet been seen, although I had looked carefully. Suddenly I realized that something Fig. 33. HABITAT OF THE ROCKY MOUNTAIN PINE had crossed my vision, and GROSBEAK, IN THE WASATCH MOUNTAINS, UTAH my eyes instantly rested on a female Grosbeak sitting on a branch of a dead as- pen. Apparently it was their trysting place, for almost p.t the same moment, the male appeared from somewhere alighting on the same branch some eight feet from the female who squatted with outspread wings and tail, in much the manner of young but fledged birds when being fed by thcir l?arents. Both birds commenced and kept up a continual twitter, the male strutting to and fro on the branch, each time drawing a little nearer to the female, and the while making obeisance, bow- ing the head as loxv as the feet, and displaying his colors with much grace, until they finally met. The female had not moved since alighting, other than the con- tinued trembling of spread tail and 'fluttering wings. The male then rubbed his head and neck against the head and neck of the female, several times up and down, then suddenly with open beak she raised her head, the male seizing her by the beak, the two commenced tugging and pulling at each other. The stroking of necks and tugging of open bill of female was gone through xvith three times,
