In presenting a list of the birds observed in this locality, I wish to call especial attention to the curious admixture of geographical races found here. Among the species which are subject to climatic variation, several are represented by two distinct varieties and with them confused and indeterminable intermediate forms. In others but one constant form is found. And in a third class the bird occurs in a varying, transitional phase of plumage which, however, occasionally becomes typical of some described race.
1. Hylocichla unalascæ (Gm.) Ridg. Dwarf Thrush.—Uncommon resident. Not heard to sing. Several of my specimens very closely approach the variety auduboni. I saw nothing of the eastern pallasi, which I have received from Mr. Geo. H. Ragsdale, of Gainesville.
2. Merula migratoria propinqua, Ridg. Western Robin.—Irregularly abundant.
3. Mimus polyglottus (Linn.) Boie. Mockingbird.—Rare resident.
4. Sialia sialis (Linn.) Haldem. Bluebird.—Comparatively common during the winter. All of my specimens were in most beautiful plumage. Not one male in a dozen showed the slightest brownish edging to the feathers of the back. I was particularly struck with this in view of the fact that almost every individual in a large series collected in Alabama, in the winter of 1878, exhibited more or less of this brownish edging.
5. Sialia arctica, Swains. Rocky Mountain Bluebird.—Abundant winter visitor. Generally in dull plumage.
6. Polioptila cærulea (Linn.) Scl. Blue-gray Gnatcatcher.—Apparently a common summer resident. Arrived March 8.
7. Regulus calendula (Linn.) Licht. Ruby-crowned Kinglet.—Abundant up to the last week in March.
8. Regulus satrapa, Licht. Golden-crested Kinglet.—Not common. Last seen about March 22.
9. Lophophanes atrocristatus, Cassin. Black-crested Tit.—Very abundant resident.
