27. Helminthophaga celata, Bd. Orange-crowned Warbler.—Seen only during migrations and very rare.
28. Dendrœca æstiva, Bd. Summer Yellow Bird.—Very abundant during migrations. Not a very common summer sojourner, but quite regularly distributed.
29. Dendrœca coronata, Gray. Yellow-rumped Warbler.—The most common of all the Warblers from November to April. Winters abundantly in this region and numbers visit the gardens, even those in the interior of the city.
30. Dendrœca maculosa, Bd. Black-and-yellow Warbler, and
31. Dendrœca blackburniæ, Bd. Blackburnian Warbler, are both, so far as I observed, exceedingly rare during migrations.
32. Dendrœca pennsylvanica, Bd. Chestnut-sided Warbler.—Somewhat common in the latter part of April and early in May.
33. Dendrœca castanea, Bd. Bay-breasted Warbler.—This elegant Warbler is one of the most common of its family during the spring migration. I observed small flocks of from eight to ten so late as May 5.
34. Dendrœca striata, Bd. Black-poll Warbler.—Transient; arrives from winter quarters late in April, when the host of Warblers pass northward. Tolerably common.
35. Dendrœca virens, Bd. Black-throated Green Warbler.—Abundant during migrations. Moves in flocks of from four to ten.
36. Dendrœca dominica albilora, Ridg. Yellow-throated Warbler.—A very rare summer resident and very difficult to observe in the high moss-grown forest trees of the river bottoms. The song resembles that of Dendrœca æstiva, but is louder and more varied. I think it is almost impossible to discover a nest of this bird in the high trees, so densely covered with Tillandsia.
