July 28, 1859 ("The sweet and plaintive note of the pewee
is now prominent, since most other birds are more hushed. I hear young families of them answering each other from a considerable distance, especially about the river.");
August 6, 1858 (“The note of the wood pewee is now more prominent, while birds generally are silent.”);
August 9, 1856 ("The notes of the wood pewee and warbling vireo are more prominent of late, and of the goldfinch twittering over.”);
August 12, 1858 ("The note of the wood pewee is a prominent and common one now. You see old and young together.");
August 18, 1858 (“One appeared to answer the other, and sometimes they both sung together, — even as if the old were teaching her young. It was not the usual spring note of this bird, but a simple, clear
pe-e-eet, rising steadily with one impulse to the end.”);
August 20, 1854 ("Saw a wood pewee which had darted after an insect over the water in this position in the air: It often utters a continuous
pe-e-e.");
August 21, 1853 ("Methinks I have not heard a robin sing morning or evening of late, but the peawai still . . ."). See also
J.J. Audubon ( "...at this season, their notes are heard at a very late hour, as in early spring. They may be expressed by the syllables
pe-wee, pettowee, pe-wee, prolonged like the last sighs of a despondent lover, or rather like what you might imagine such sighs to be, it being, I believe, rare actually to hear them.")
