26 UPTON, MAINE 1872 June 2 - 14 ance (for description of song see T.pallasii above). All spe- cimens typical. 9. T. aliciae. Took a typical specimen June 3 at which time several northern species were still migrating. T. migratorius. Extended everywhere into the depths of the forest but common nowhere. Young were flying at our arrival, June 2. (Very common in 79) Regulus satrapa. Quite rare this season: heard only one or two specimens. (Rare in 73--for song see diary) (Mniotilta varia we noticed quite frequently up to Grafton notch where it entirely stopped.) Parula Americana. Not common this season. (Very common in 73) G. trichas. Common in the clearing and living and breeding in the hilly pastures in piles of fallen tree tops in company with the following species. G. philadelphia. Rather common but restricted locally: found them altogether in high open land along the brush fences and old log heaps rarely far from the edge of the woods, and indeed sometimes a considerable ways in, in little sunny clearings, but never in the gloomy depths of the forest. In all their mo- tions they closely resembled G. trichas keeping usually on or near the ground: from that bird they were readily distinguished however by the different markings of the head and throat and in- deed bore, alive, a striking resemblance to O.agiles: they were also more retiring and timid than G. trichas and harder to take, plunging at once into their favorite thickets when alarmed.
