636 MICHIGAN BIRD LIFE. 
It was composed of dry grass and sunken level with the surface of the 
eround. The eggs were four, creamy white, with a few spots of lilac- 
purple, brown, and black, and measured .75 by .56 inches. 
There is little doubt that the Connecticut Warbler nests regularly in 
parts of Northern Michigan, but it is usually confused with the Mourning 
Warbler, which is far more plentiful. Thus records unsupported by 
specimens must be received with the greatest caution. Recent captures 
in the southeastern part of the state indicate that the bird is to be found 
more frequently than is generally supposed. Mr. P. A. Taverner, in his 
manuscript list of the birds of St. Clair county, says: “I do not think 
this bird as rare as is generally supposed, as I have taken one every year 
for the last six years wherever I have been. The finding of them seems 
to be more in knowing where to look and looking.” Mr. N. A. Eddy, of Bay 
City, has two skins in his collection taken on Heisterman’s Island, Saginaw 
Bay, September 2, 1889, and Mr. N. A. Wood found it common on Charity 
Island, Saginaw Bay, September 1, 1910. He says ‘‘I saw more in one 
day than in all my life before.’ Mr. 8. E. White took two specimens 
on Mackinac Island, one August 30, 1889, and the other August 30, 1890. 
Mr. J. Claire Wood has secured one or more specimens near Detroit, 
and Mr. B. H. Swales gives a list of six or seven specimens taken in that 
vicinity in recent years (Wilson Bulletin, No. 53, 1905, p. 109). Peet 
records several seen on Isle Royale September 12, 1905. Apparently 
the first specimens taken in the state were one secured by Dr. H. A. Atkins 
at Locke, Ingham county, May 30, 1879, and one taken by C. W. Gunn in 
Ottawa county May 22, 1879. Others were taken near Kalamazoo on 
May 17, 1880, May 27, 1881 and May 28, 1883. A specimen was killed 
on Spectacle Reef Light, Lake Huron, October 3, 1893.

Synonyms: Black-throated Ground Warbler, Crape Warbler.—Sylvia philadelphia, 
Wilson, 1810.—Trichas philadelphia, Jardine, 1832.—Geothlypis philadelphia, Baird, 
1858, and most subsequent writers. 
Very similar to the Connecticut Warbler, but lacks the white eye-ring 
and has more or less black on the breast. See notes under Connecticut 
Warbler. ; 
Distribution.—Eastern North America to the Plains, breeding from the 
mountainous portions of Pennsylvania, New England, New York, and 
northern Michigan northward. Central America and northern South 
America in winter. 
A beautiful and not generally well known migrant throughout the whole 
state, and a not uncommon summer resident in its northern half. Many 
observers call it rare, but a good collector will have little difficulty in 
finding it in some numbers during the latter half of May and again in 
September and early October. It is one of the latest warblers to arrive
