fiTty feet from the ground. It was formed much in the manner of the King-bird's, externally made of interlaced dead twigs of the cedar, internally of wiry stolons of the common cinquefoil, dry grass, and some fragments of branching lichen or usnea. It contained three young, and had
probably four eggs. The eggs had been hatched about the 20th of June,
so that the pair had arrived in this vicinity about the close of May.
The young remained in the nest no less than twenty-three days, and were
fed from the first on beetles and perfect insects, which appeared to have
been wholly digested, without any regurgitation. Towards the close of
this protracted period, the young could fly with all the celerity of their
parents, and they probably went to and from the nest before abandoning
it. The male was at this time extremely watchful, and frequently fol-
lowed me from his usual residence, after my paying him a visit, nearly
half a mile. These birds, which I watched on several successive days,
were no way timid, and allowed me for some time previous to visiting
their nest, to investigate them and the premises they had chosen, without
showing any sign of alarm or particular observation."
I received from my friend the following additional account, in a letter dated September 12. 1833. "Something serious has happened to our pair of the new Flycatchers [Musckapa Cooperi), which have for three years at least, bred and passed the summer in the grounds of Mount Auburn. This summer they were no longer seen. It is true they were not very well used last year ; for, in the first place, I took two of the four eggs they had laid, when they deserted the nest, and soon, within little more than a stone's-throw, they renewed their labours, and made a second, which was also visited ; but from this I believe they raised a small brood. The nest, as before, was placed on a horizontal branch of a red cedar, and made chiefly of the smallest interlaced twigs collected from the dead limbs of the same tree, in all cases so thin, like that of the Tanager, as to let the light readily through its interstices. An egg you have, which, as to size, so completely resembles that of the Wood Pewee, as to make one and the same description serve for both ; that is to say, a yellowish cream-white, with spots of reddish-brown, of a light and dark shade. All the nests, three in number, were within 150 yards of each other respectively. I saw another pair once in a small piece of dry pine wood in Mount Auburn one year ; but they did not stay long. A third pair I saw the summer before the last, on the edge of the marsh towards West Cambridge Pond ; these appeared resident. The next pair I had
