In size it is also a little smaller. Specimens from Mirador (where breeding) and those from New Mexico are nearly identical in size, proportions, and colors.
Habits. This remarkable Grosbeak was first described by Mr. William Cooper, from specimens obtained by Mr. Schoolcraft in April, 1823, near the Sault Sainte Marie, in Michigan. Sir John Richardson soon after found it to be a common inhabitant of the maple groves on the plains of the Saskatchewan, where it is called by the Indians the “Sugar-Bird.” He states that it frequents the borders of Lake Superior also, and the eastern declivity of the Rocky Mountains, in latitude 56°.
Captain Blakiston did not find this Grosbeak on the Saskatchewan during the summer, but only noticed it there during the winter. He saw none after the 22d of April, and not again until the middle of November. They were seen in company with the Pine Grosbeak, feeding on the keys of the ash-leaved maple. He adds that it has a sharp clear note in winter, and is an active bird.
Dr. Cooper, in his Notes on the Zoölogy of Washington Territory, states that this species is a common resident in its forests, but adds that as it frequents the summits of the tallest trees, its habits have been but little observed. In January, 1854, during a snow-storm, a flock descended to some
low bushes at Vancouver, and began to eat the seeds. Since then he had only seen them flying high among the tops of the poplars, upon the seeds of which they feed. They were uttering their loud, shrill call-notes as they flew.
The same writer, in his Report on the birds of California, makes mention of the occurrence of this Grosbeak at Michigan Bluffs, in Placer County, in about latitude 39°. Specimens were obtained by Mr. F. Gruber, and were probably the variety designated as montana. The same form doubtless occurs along the summits of the Sierra Nevada, and they have been traced among the Rocky Mountains to Fort Thorn in New Mexico.
These birds do not come down near the sea-coast even at the mouth of the Columbia, and in California have not been met with in the Coast Range. They are said to feed chiefly on the seeds of the pine, spruce, and cottonwood trees, occasionally seeking other seeds near the ground. They are silent when feeding, but utter a loud call-note as they fly from place to place. In spring, Dr. Cooper states, they have a short but melodious song, resembling that of the Robin or Black-headed Grosbeak. He afterwards met with a flock in the winter near Santa Cruz, where they remained until the end of April. Their favorite resort was a small grove of alders and willows, close to the town, where their loud call-notes could be heard at all times of the day, though he never heard them sing. In the early spring their favorite food was the young leaves of various wild plants that grew under the trees. They also fed on the buds of the Negundo, and frequented the large pear-trees in the old mission garden. They were very tame, and allowed an approach to within a few yards, when feeding. Mr. Townsend, in 1836, found this Grosbeak abundant about the Columbia River. Late in May they were quite numerous in the pine woods. They were very unsuspicious and tame. Under the impression that these birds were only musical towards night, they have been styled the Evening Grosbeak. But this, according to Mr. Townsend, is a misnomer. He also contraverts several other statements made in reference to their habits. He found them remarkably noisy from morning until night, when they quietly retire like other birds, and are not heard from until the next day-dawn. They go in large flocks, and are rarely met with singly. As they feed upon the seeds of the pine and other trees, they proceed by a succession of hops to the extremities of the branches. They also feed largely on the larvæ of the large black ant, for which object they frequent the tops of the low oaks on the edges of the forests. Their ordinary voice is said to be a single screaming note, uttered while feeding. At times, about midday, the male attempts a song, which Mr. Townsend describes as a miserable failure. It is a single note, a warbling call like the first note of the Robin, but not so sweet, and suddenly checked, as if the performer were out of breath.
Mr. Sumichrast met with the variety of this species designated as montana, May, 1857, in the pine woods of Monte Alto, about twelve leagues from Mexico; and although he has never found it in the alpine region of Vera
Cruz, he thinks it probable it will be found to be a resident of that district.
Lake Superior has been stated to be its most eastern point of occurrence, but, though this may be true as a general rule, several instances of the accidental appearance of this nomadic species much farther to the east are known. On February 14, 1871, Mr. Kumlien, while out in the woods with his son, saw a small flock of these birds in Dane County, Wisconsin. There were six of them, but, having no gun, he did not procure any. Later in the season he again met with and secured specimens. In the following March, Dr. Hoy of Racine also obtained several near that city. He also informs me that during the winter of 1870-71 there were large flocks of these birds near Freeport, Ill. One person procured twenty-four specimens. One season he noticed them as late as May. They frequent the maple woods, and feed on the seeds fallen on the ground. They also eat the buds of the wild cherry. Their visits are made at irregular intervals. In some years not a single individual can be seen, while in others they make their appearance in December and continue through the whole winter.
