26. Geothlypis philadelphia (Wils.) Bd. Mourning Warbler.—Common in suitable places. It was almost sure to be found in “burnt lots,” where the fallen trunks lay, half hidden by a luxuriant growth of tall weeds, or thickly overrun with vines. Under the shelter thus afforded they undoubtedly nested, safely screened from the most searching eyes.
27. Geothlypis trichas (Linn.) Caban. Maryland Yellow-throat.—Common.
28. Myiodioctes pusillus (Wils.) Bp. Wilson’s Black-cap.—At Fort Fairfield this bird was common. We usually found them in thickets of willow bushes, often in rather wet places. The birds were apt to go in companies of three or four or more. June 23 Mr. Dwight caught a young bird, just able to fly two or three yards at a time. The nest was no doubt close at hand, but the ground among the willow bushes was covered so deeply with brush that a diligent search for the nest showed nothing—except that it was not built in the bushes. The youngster showed in the most marked way the energy of disposition and restless activity that characterize the adults. The species was not common at Grand Falls.
29. Myiodioctes canadensis (Linn.) Aud. Canada Flycatching Warbler.—Rare at Grand Falls, but common at Fort Fairfield.
30. Setophaga ruticilla (Linn.) Swains. Redstart.—This species was exceedingly abundant at Grand Falls wherever there were hard woods. It was a common bird at Fort Fairfield.
31. Hirundo erythrogastra Bodd. Barn Swallow.—Common.
32. Tachycineta bicolor (Vieill.) Caban. White-bellied Swallow.—At Grand Falls it was common in suitable localities. None were seen about the town. It was abundant at Fort Fairfield.
33. Petrochelidon lunifrons (Say) Lawr. Eave Swallow.—Common at Grand Falls. Abundant at Fort Fairfield.
34. Cotile riparia (Linn.) Boie. Bank Swallow.—Common.
35. Progne subis (Linn.) Bd. Purple Martin.—Common, breeding in martin-houses at Fort Fairfield. This bird seems to be generally distributed throughout eastern Maine and the adjoining parts of New Brunswick, where there are settlements. While on our way to Fort Fairfield we noticed it at a number of places between Bangor and Woodstock, N. B., as well as at various points along the St. John River between Fredericton, N. B., and Fort Fairfield. It is also common at Houlton.
