R., May 2 to Aug. 27. Nest, bulky. of twigs and rootlets, firmly wrapped with several thicknesses of leaves, lined with line rootlets, on or near the ground. Eggs, four to five. white or grayish white, finely and evenly speckled or coarsely blotched with rufous to umber, '72 x '58. The Kentucky Warbler frequents rather densely grown, well— watered woods. Here he may be found, on or near the ground, hop- ping from limb to limb or walking about searching for food. When singing, he generally mounts to the lower branches of the higher trees. His song iS'eutirely unlike that of any other Warbler. It is a loud, clearly whistled performance of five, six, or seven notes—tur—dle, tur- dle, tur—dle—resembling in tone some of the calls of the Carolina Wren. Even in the woods it may be heard at a distance of about one hundred and fifty yards. In the height of the breeding season this Warbler is a most per- sistent singer. On one occasion, at Englewood,- N. J ., I watched a. male for three hours. During this period, with the exception of five interruptions of less than forty-five seconds each, he sang with the greatest regularity once every twelve seconds. Thus, allowing for the brief intervals of silence, he sang about 875 times, or some 5,250 notes. 1 found him singing, and when I departed he showed no signs of ceasing. 878. Geothlypis aging (Wile).
