Connecticut Warbler (Oporornis agilis).—Not uncommon about the middle of May, but very shy. Frequented the borders of the swamp, and escaped into the thick button-bushes when surprised.
Kentucky Warbler (Oporornis formosa).—One of the most abundant of the summer residents.
Mourning Warbler (Geothlypis philadelphia).—Became suddenly very common May 6. Frequented chiefly brush-piles and old fences. Most of the specimens observed were males in fine plumage.
Black-capped Yellow Warbler (Myiodioctes pusillus).—Rare during migration.
Canada Flycatching Warbler (Myiodioctes canadensis).—One of the most numerous of the migratory species; first noted April 18, but not common until a week later.
Hooded Warbler (Myiodioctes mitratus).—Rather common in deep woods, but much less so than in the vicinity of the Cypress swamp, further south.
Solitary Vireo (Lanivireo solitarius).—Rare.
Cedarbird (Ampelis cedrorum).—Exceedingly numerous among the willows in the swamp, where feeding upon the larvæ of Diabrotica 12–maculata infesting these trees.
Summer Redbird (Pyranga æstiva).—Rather common, but owing to the comparative absence of high, dry woods, much less so than near Mt. Carmel. A female, killed at the same shot with her mate, resembled the male except in the tint of the red, which was of a brick-red rather than vermilion, the male also being in the parti-colored plumage of the immature bird, the red occupying, in both male and female, one-half or more of the plumage. The ovaries of the female were well developed.
Grass Finch (Poœcetes gramineus).—Common in the meadows, a nest with four eggs being taken April 30.
