240 KENTUCKY WARBLER 



Nest. — A nest from Englewood, N. J., is very bulky. An outer 

 wrapping of several layers of dead leaves encases a wall of weed 

 stalks while the heavy lining consists of black rootlets. A nest from 

 Wheatland, Indiana, essentially agrees with this New Jersey speci- 

 men. 



"A rather bulky and loosely constructed nest, outwardly of some- 

 what ragged dead leaves of the chestnut, beech, cherry, maple, white, 

 black, and chestnut oak, a few weed or grass stems, an occasional 

 strip of wild grapevine bark, and, once, many green leaves of the 

 dogwood, and, in another example, several oak blossoms; usually fol- 

 lowed by an inner layer of bright, clean dead leaves of the beech, 

 lined with black rootlets and in fully half of the nests examined, a few 

 long black horse-hairs. In one instance the lining was of light-colored 

 rootlets. Another nest, so well hidden in a patch of woodplants that 

 I accidentally trod upon it while actually searching for it, was a most 

 frail affair built exclusively of grasses, lined with black rootlets, how- 

 ever. 



"During the nest building period the birds are so extremely 

 jealous and watchful, deserting the site rather than be spied upon, that 

 I have been unable so far to follow this interesting period to a finish. 

 The male unquestionably aids his mate." (Burns, MS.) 



Eggs. — 4 or 5, in about even proportions. Ground color white, 

 in some cases very glossy, spotted and specked, rarely blotched, with 

 burnt umber, cinnamon-rufous and lilac-gray, seldom if ever showing 

 under shell markings ; in most cases the markings are heavier 

 at the large end, sometimes in a mass, sometimes well wreathed, 

 and in other types evenly distributed over entire egg. Size ; average, 

 .74X.58; extremes, .79X.60, .69X.57, .73X.54. (Figs. 100,101.)
