43 UPTON, MAINE 1873 August 10 - 11 August 10. (Sunday) Clear, warm and pleasant. Lounged around the house in the morning: in P.M. took a sail down to the mouth of the river with Smith. August 11. Clear, rather hot but a fine day. After breakfast went out behind the barn and shot a D.tigrina y.y., a Parus hudsonius y.y. (Flying) and two Sp.varius nestlings. Sialia sialis is getting quite common here, a sure indication that the migrations are commencing as it is rare in the breeding season. The note of P.hudsonius is not to be mistaken for that of P.atricapillus, it is shorter (I have heard only one note besides the lisping chirp common to all of the genus) and feebler like chee, shee-shee this note corresponds to the chick a dee dee dee of P. abri. Sp.varius is a very remark- able bird in its actions: it is tame almost to stupidity, or perhaps rather, like the woodcock and quail, it depends on concealment instead of flight for safety as it will allow me frequently to approach within a few feet and when fired at and missed, will flatten itself against the bark and remain per- fectly motionless. In P.M. went down river and took a brood of four very young nestlings D.caerulescens: both old birds were in attendance and the whole family moved rapidly along through the woods, flying from tree to tree, the young twittering loudly: one chirp or rather cluck of the adlt. is precisely like that of Junco hyemalis. Took also a P.savania in nestl. plum. and a do. Troz.Hyemilis. Mr. Monheimer with a party of eleven ar- rived at 6.
