LAND BIRDS. 621 
The specimens taken in the United States were collected in widely separate 
localities, but by far the larger number in Ohio and Michigan. The follow- 
ing is the list of specimens taken in Michigan, as given by Mr. Norman A. 
Wood in March 1904:* Two females, collected at Ann Arbor by A. B. 
Covert, May 15, 1875 and May 16, 1879; 1 male, collected by N. Y. Green 
at Battle Creek, Michigan, May 11, 1883; 1 male, found dead at foot of 
Spectacle Reef Lighthouse, Lake Huron, by the keeper, William Marshall, 
May 21, 1885; 1 male, collected by L. Knapp, at Ann Arbor May 18, 1888; 
1 specimen, collected by F. H. Chapin, Kalamazoo county, Mich., in 1898; 
1 female, collected by Norman A. Wood, at Ann Arbor May 14, 1902; 
1 male, collected by T. G. Gale, near Luzerne, Oscoda county, Mich., June 
15, 1903, and 7 adults and 7 nestlings, collected in Oscoda and Crawford 
counties, Michigan, by Norman A. Wood, between July 2 and July 15, 
1903. 
During the years which have since elapsed the taking of this warbler, 
or its nest and eggs, has been contrary to the law of the state and few speci- 
mens have been recorded. Doubtless, however, several have been taken, 
and competent observers have reported the bird as seen in various parts 
of the jack-pine plains north of 44°. During the past summer (1911) the 
writer visited various parts of the jack-pine plains, outside of the known 
nesting range of Ixirtland’s Warbler, in the hope of extending this area 
and perhaps adding something to the knowledge of the species. Eight 
days (July 1 to 8) were spent in the search, but the season was so far ad- 
vanced and the heat so intense (exceeding 100° on all but two days) that 
the conditions were very unfavorable and the trip was entirely fruitless 
so far as this species was concerned. The areas examined included large 
and promising stretches of pine lands in Lake, Manistee, Wexford, Grand 
Traverse, Kalkaska and Crawford counties, as well as some of the better 
hardwood lands of Antrim and Otsego counties. No trace of the warbler 
was found, however; either it did not inhabit the localities visited or had 
ceased to sing, owing to the late date and the intense heat. The latter 
explanation is at least possible and it must not be assumed that the species 
does not occur in some of these places, at least occasionally. 
Comparatively little is known of the habits of this rare warbler. An 
excellent resume of our knowledge of the species up to 1898 is given by 
Mr. F. M. Chapman in the Auk, Vol. 15, 1898, pages 289-293, ‘accompanied 
by a good colored plate (two figures) by Fuertes. A full aecount by 
Norman A. Wood of the discovery of the breeding area, with description 
of the nest and eggs, will be found in the Bulletin of the Michigan Ornitho- 
logical Club, V, 1904, pages 1-13; following which, on pages 14 to 21, is an 
article by Dr. Chas. C. Adams on the migration route of Kirtland’s Warbler. 
From these sources the following brief account is condensed: 
During the winter Kirtland’s Warbler apparently ranges through the 
Bahama Islands, and begins its northward migration in April, reaching 
South Carolina about the end of that month. It has been reported from 
Illinois May 7, from Indiana May 4 and 7, from Ohio May 12 and 13, from 
Battle Creek, Mich., May 11, from Ann Arbor May 15, 16 and 18, and from 
Spectacle Reef Light, Lake Huron, May 21. The records, few as they are, 
show that the birds are widely scattered during the northward migration, 
and although a considerable proportion would indicate that they were on 
their way to the known nesting region in northern Michigan, it seems 
extremely likely that the breeding area covers a much larger territory
