WARBLERS 107 



Kirtland's Warbler has one of the smallest nesting areas 

 of any North American bird and consequently is one of 

 our rarest species. In the summer it lives among 

 the jack-pines of north central Michigan, nesting on the 

 ground beneath them. When migrating, it may be found 

 usually near the ground, where it may be identified 

 by its habit of tail-wagging. Its song is described 

 by Wood in "Warblers of North America" as belonging 

 to the whistling type with the clear, ringing quality of the 

 Oriole's. The 3-5 eggs, laid early in June, are white 

 speckled with brown in a wreath at the larger end.

Pine Warblers seem almost as much a part of pine 

 woods as the trees themselves. They feed on the ground 

 below the pines, they glean from the bark of the trunk, 

 or frSm the clusters of 'needles' on the topmost boughs, 

 the very peace of the pines is expressed in their calm, 

 even, musical trill; and where there are no pines there 

 are no Pine Warblers. During the migration, it is true, 

 they may be found elsewhere, but at that season they are 

 travelers, and travelers cannot always be responsible for 

 their surroundings. Their nest, of course, is always built 

 in pines, usually from 30-50 feet above the ground. The 

 eggs laid in March in the South, and early June in the 

 North, are white wreathed with brown at the larger end.
