a hazel stem running horizontally. Its cavity measures one and seven-eighths by two inches. It differs 

 in construction from the one above described, in that it is fastened at the rim to the horizontal twig 

 and has a few horse-hairs in the lining. 



All the nests of this species which I have seen have been remarkably uniform in size and materials 

 of construction, but from descriptions of nests found at various times in different parts of the United 

 States, there seems occasionally to be considerable variation. One nest is stated to have been four inches 

 in outside diameter. Another is said to have been lined with woolly vegetable-down and horse-hair; and 

 another has been found which was nearly pensile, its lower two-thirds being entirely free from any 

 supporting twig. These and other variations are, however, no greater than is to be expected, as such 

 variations from the common type occur to a greater or less extent in the nests of every species. 



EGGS: 



The number of eggs in a set is either four or five, usually four. They measure between .57 and .69 

 in long-diameter, and betweeen .46 and .51 in short-diameter. A common size is about .48 x .64. The 

 ground-color of the shell varies from nearly pure white to a slight creamy tint, and occasionally even to 

 a faintly greenish or bluish tint. The following description of six eggs will comprehend the usual varia- 

 tions. No. 1. Size, .49 x .60. Ground-color white. Markings, confined to a wreath about the base, con- 

 sist of blotches, spots, and speckles, slightly confluent in places, of several shades of Vandyke-brown. 

 Deep shell-marks numerous, lavender. No. 2. Size, .46 x .58. Ground-color faintly buff-tinted. Markings 

 confined to a broad wreath about the base, of confluent deep shell-marks and surface blotches, spots, and 

 speckles. The deep shell-marks are chiefly blotches, and are decidedly lavender color. The surface marks 

 are brown and superimposed upon these. No. 3. Size, .48 x .66. Ground-color slightly greenish tinted. 

 Markings confined to ring about the base, composed of numerous but well defined spots and speckles of 

 dark brown. Deep shell-marks and surface marks are about equal in number, the former are lavender. 

 No. 4. Size, .48 x .65. Ground-color soiled white. Marking distributed over entire shell, but most 

 numerous at the base. These are blotches, spots, and speckles of various shades of light brown, having 

 well defined outlines, which at the base occasionally overlap or fuse into each other. The speckles are 

 plentiful over the entire shell, and are placed on the blotches and spots as well as on the white ground. 

 The lavender, deep shell-marks are few and small. No. 5. Size, .49 x .63. Ground-color slightly greenish 

 tinted. Markings similar to No. 4, except that the speckles are fewer and the browns are darker. No. 

 6, similar to No. 2 in size and ground-color. Markings few and confined to base. Some of the larger 

 blotches are nearly black in the center, with faded edges. Deep shell-marks well defined, lavender.

REMARKS : 



The nests and eggs illustrated, were found in June, 1883, in a small upland woods. The nest was 

 in a hazel fork, in a dense thicket of briars and other bushes, within a few yards of a country road. 

 It is a good example of the architecture of this species. The eggs, three in number, show the common 

 shapes and markings, but they are a little less than the average in long-diameter. 



It is impossible to say how many nests have been taken in Ohio. In 1852, Mr. Reed stated it was 

 rather common in Northern Ohio, and he found and described a nest which, in locality and position, 

 corresponds exactly with those I have discovered. Careful observation will probably place this Warbler 

 on the list of summer residents in the southern as well as in the northern part of the State. In Central 

 Ohio I have several times found it nesting, and in the extreme southern limits I have seen it in July.
