the tallest trees of the forest, as if to rest a while. While on wino- it
utters a clear note, but when perched it remains silent, in an upright and
rather stiff attitude. It is then easily approached. I have followed it in
its migrations into Pennsylvania, New York, and other Eastern States,
through the British provinces of New Brunswick and Nova Scotia, as far
as Newfoundland, where many breed, but I saw none in Labrador. It is
never seen in the maritime parts of Georgia, or those of the Carolinas,
but some have been procured in the mountainous portions of those States.
I have found them rather plentiful in the early part of May, along the
steep banks of the Schuylkil River, twenty or thirty miles from Phila-
delphia, and observed, that at that season they fed mostly on the buds of
the trees, their tender blossoms, and upon insects, which they catch on
wing, making short sallies for the purpose. I saw several in the Great
Pine Forest of that State ; but they were more abundant in New York,
especially along the banks of the beautiful river called the Mohawk.
They are equally abundant along the shores of Lakes Ontario and Erie,
although I believe that the greater number go as far as New Brunswick
to breed. While on an excursion to the islands at the entrance of the
Bay of Fundy, in the beginning of May, my son shot several which were
in full song. These islands are about thirty miles distant from the mainland.
The most western place in which I found the nest of this species was within a few miles of Cincinnati on the Ohio. It was placed in the upright forks of a low bush, and differed so much in its composition from those which I have seen in the Eastern States, that it greatly resembled the nest of the Blue Grosbeak already described. The young, three in number, were ready to fly. The parents fed them on the soft grains of wheat which they procured in a neighbouring field, and often searched for insects in the crannies of the bark of trees, on which they alighted sidewise, in the manner of sparrows. This was in the end of July. Generally, however, the nest of the Rose-breasted Grosbeak is placed on the top branches of an alder bush, near water, and usually on the borders of meadows or alluvial grounds. It is composed of the dried twigs of trees, mixed with a few leaves and the bark of vines, and is lined with fibrous roots and horse hair. The eggs are seldom more than four, and I believe only one brood is raised in the season. Both sexes incubate. I have found the nest and eggs, on the 20th of May, on the borders of Cayuga Lake in the State of New York.
