5 UPTON, MAINE 1871 19. Contopus borealis, quite numerous; affected the edges of the clearings and hilly pastures where they perched Hawk like on the very tops of the highest "stubs": never saw them in the flooded forests, though they were the favorite resort of T.Carolinensis. 20. Contopus virens, saw but very few, these in the depths of the forest. 21. Empidonax traillii, probably occurs though we did not detect it here: found it quite frequent, however, at Newcry, some twelve miles down on the stage road where we took several spe- cimens. Its favorite resort here as at Gorham, N.H. were the alder thickets along the borders of small "rivers" and streams. All that we saw were perched on the tops of tall trees over their dense retreats, and singing vigorously in the full blaze of the noonday sun: their note was a single Ke wing uttered in a harsh peevish tone at an interval of about thirty seconds, and varied occasionally to Ke wink or Ke winch. At each utter- ance the head was thrown upward with a sudden jerk. They were easily approached and apparently not nearly so restless as most of the Flycatchers. 22. E.minimus, very common; most partial to the swampy thickets near the lake though found everywhere through the woods. 23. E.flaviventris, found only in the cedar swamps where it was not uncommon. Took five specimens during our stay which were all we saw. Found them quite tame and unsuspicous keeping al- ways however in the deepest gloomiest shade, and occasionally
