83 UPTON, MAINE 1874 August 29 other as he disappeared in the thicket. The bird killed had his crop filled with larch needles. S. fired at a H.columba sitting but missed. I heard a P.arcticus and a Canada jay. August 29. Clear and very hot. Off after breakfast with S. taking the Tyler road. Made a very good mornings work of it taking 6 good birds, 2 Vireo Philadelphicus, 1 D.blackburniae, 1 H.peregrina, 2 My.canadensis adult, 1 Vireo solitarius. S. took 1 V.Phil. and D.castania and etc. He shot the first vireo when I immediately started after the heterogeneous assembly of warblers, chickadees and etc. among which he found it and soon detected and shot two. They were both very tame, uttered no note, and, contrary to observations made on this species in June 1872, appeared even more active in their motions than the other vireos and indeed quite as much so as any of the Dendro- icidae. Two of the three were in the act of eating a large greenish caterpillar when shot. They were all killed in a low second growth of birch and maple and I should judge their habits in this respect may be analogons to those of V.noveboracensis. I obtained S.'s specimen in exchange for the spruce grouse shot yesterday. Upon dissection they proved to be all ♂ , one of them as I thought adult. One of the My.Can. was an adult ♀ in fall plumage, a most beautiful bird: he was in full song. Birds of all kinds seemed very numerous to-day. We struck one flock of warblers which must have contained over 100 individuals. I find that a few Hirundo horreorum are still left: all the other species have, I think, left. We struck two broods of rf.grouse
