LAND BIRDS. 623 
Mr. Wood watched ‘went to the top of an old burnt stub (about twenty 
feet high) nearby and sang ‘wichi chee-chee-cher-r-r.’. The song of this 
male was not so loud and ringing, and was not so full of melody as the 
first, but was very sweet and clear. It made me think of the song of the 
Maryland Yellowthroat, only the notes were shorter. * * * * often 
saw these birds alight on the ground, and think them to be as terrestial 
as Dendroica palmarum. The food of this warbler seemed to be span- 
worms living upon jack-pines, and a small light-colored span-worm moth 
(Diastictis). I saw the warbler capture these moths during flight. I 
also shot a male Kirtland that came to a nest with a deer-fly in his mouth, 
so that flies and other insects, as well as span-worms, may compose their 
food. On describing the bird, its food and its habits, to a young man who 
lives a few miles northwest, on the North Branch, he said the birds were 
there and were called ‘“‘the jack-pine bird.’ I consider this a very appro- 
priate name, as most of their time is spent on these trees and the bulk 
of their food is gleaned from them. It is not, however, every jack-pine 
plain that is the home of a colony, as I examined hundreds of acres where 
the conditions seemed all right and found none.” 
Several observers speak of the resemblance of this bird in action to 
the Palm Warbler, particularly in the wagging motion of the tail. The 
somewhat stiff and erect attitude of the bird in singing has also been noted, 
and the figure given by C. J. Maynard (Birds of Eastern North America, 
plate 17) represents correctly, according to Mr. N. A. Wood this “very 
characteristic upright singing attitude.’”’ In size and general appearance 
Kirtland’s Warbler suggests a young autumn specimen of the Myrtle 
Warbler (Dendroica coronata), but lacks the yellow rump and crown 
patch, has no black patches on the sides of the breast, and the wing-bars 
are very narrow, dull and inconspicuous. The black-streaked yellow 
under parts remind one of the Prairie Warbler, but that is a much smaller 
bird, the yellow of the under parts is much brighter, and it also has bright 
yellow on the sides of the head, where Kirtland’s Warbler is blackest. 
The upper parts are entirely unlike in the two birds.

283. Pine Warbler. Dendroica vigorsi (.lud.). (671) 
Synonyms: Pine-creeping Warbler, Pine Creeper.—Sylvia vigorsii, Aud., 1828.— 
Sylvia pinus, Wils., 1811, Bonap., 1824, Nutt., 1832, Aud., 1834.—Dendroica and Dendreeca 
pinus of many of the older naturalists, Dendroica vigorsii, Ridgw., 1885, and most sub- 
sequent authors. 
The adult male may be known by the olive-green upper parts; clear 
yellow throat and breast, without streaks; two narrow white wing-bars, 
and long oblique white patches on the outer tail-feathers. Females and 
immature birds will be likely to puzzle any but the expert. 
Distribution.—Eastern United States, west to the Plains, north to
