LAND BIRDS. G21 



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 w'arbler, 

 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 Kirtland'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 account 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 ai)i)arently ranges through the 

 Bahama Islands, and begins its northward migiation 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 IMay 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 ai-e widely scattered during the northward migration, 

 and although a consideral)lc proportion would indicate that they were on 

 their way to the known nesting i-egion in northern Michigan, it seems 

 extremely likely that the breeding area covers a much larger territory
