Nesting.—Wayne was under the impression that he was the discoverer of the first known nest of this race, but search of the literature reveals that he was in error, though the first nests found were not recognized as those of waynei. Wayne secured the first eggs, and these still appear to be the only ones in existence, as all other breeding records deal with young birds. Authentic breeding information is exceedingly scanty, and since this is the case, all of the instances are mentioned herewith.
The first recorded breeding was in coastal North Carolina, and is mentioned by Pearson and the Brimleys (1919). They included it under the black-throated green warbler, as the species at that time had not been divided into two races. One nest was found at La Grange, Lenoir County, in June 1905 (Smithwick), and the other at Lake Ellis, Craven County, June 1910. Adults were seen feeding very young birds.
Continually impressed with the birds’ presence in coastal South Carolina so late in spring, Wayne sought evidences of nesting and, on April 11, 1917, saw a female carrying nesting material in a large cypress swamp in Charleston County, but could not locate the nest. On the twenty-eighth of the same month he detected both a male and female in the same procedure but again failed to find the nest. His (1918) comment on this follows: “The brief account of this bird written in ‘Birds of South Carolina’ is, in the main, correct. Although I had never found it breeding when the book went to the press I was absolutely certain that it really bred on the coast.” A year later, on April 28, 1918, he saw another female engaged in nest building, and again was unable to find the nest. Those who knew Wayne’s untiring energy in such work can readily understand the extreme difficulty experienced in locating this elusive bird’s home. It was on this last date that he secured the type specimen from which Bangs described the race. The following year finally brought success. Wayne (1919) states:
“On March 20, 1919, I visited the place where the type specimen was taken. * * * A few males were heard singing from the topmost branches of tall, gigantic, deciduous trees, and were also seen to fly into very tall pines.” He again visited this spot on April eighteenth with Henry Moessner and the latter located a nest. It "was built in a live oak tree and on the end of a horizontal branch among twigs * * * absolutely concealed * * * about 38 feet above the ground.” Wayne climbed a nearby tree and with Moessner’s help from below, attempted to pull the oak limb toward him in order to reach the nest, when “sad to relate, without a moment’s warning, the limb snapped off and the four fresh eggs that the nest contained were dashed in fragments on the ground.”
The nest itself was preserved, and Wayne describes it as “small and compact, measuring 13⁄4 inches in height and 11⁄2 inches in depth. It is constructed of strips of fine bark and weed stems, over which is wound externally the black substance that is invariably present in the lining of the nests of Bachman’s Warbler (Vermivora bachmanii). The interior * * * is chiefly composed of a beautiful ochraceous buff substance, doubtless from the unfolding leaves of some fern, and a few feathers.”
On the twenty-eighth, ten days after this nest was found, Wayne returned to the swamp with the Misses Louise Ford and Marion Pellew and found “a very young bird just from the nest and unable to fly more than a few feet, being fed by the male parent, which shows that the birds breed irregularly.”
The party proceeded to another part of the swamp where a female was seen to enter a large magnolia. “Miss Ford * * * saw the female go to her nest * * * built near the extremity of a long drooping magnolia limb, but on the horizontal portion of it and about 25 feet above the ground.” This nest held four heavily incubated eggs, these being the first ones actually taken. This nest had a quantity of caterpillar silk binding the fibres of Spanish and hypnum moss outside, and was “lavishly lined with the beautiful ochraceous buff substance from young fern leaves, as in the first nest.”
Edward S. Dingle (MS.) writes that “on the morning of April 25, 1923, a Wayne’s warbler was observed building in a cypress tree; the bird collected material from the ground and also from the trunk of a large cypress nearby. The male was not seen.” On the third of May following, I accompanied Wayne and Dingle to the site; there Dingle located the nest, climbed the tree, and secured it, with four eggs. This nest was 62 feet from the ground and 5 feet out from the trunk. This is the third, and last nest from South Carolina with eggs, on which data are extant. All, with the exception of the first, were in Wayne’s collection at his death, and are now in the Charleston (S. C.) Museum. The sites in each case, were found by Wayne, but the nests were actually located by Moessner, Dingle, and Miss Ford.
Commenting on these discoveries, Wayne (1919) states: “I have known this bird ever since May 4, 1885 when I took a male in Caw-caw Swamp, Colleton County, S. C., while on a collecting trip with my friend, the late William Brewster. I gave the bird to him in the flesh, and in his collection it still remains. The nest and eggs have remained unknown until brought to light by this season’s research.”
Russell Richardson (1926) reported black-throated green warblers in the Dismal Swamp, on the North Carolina side, in June. No evidence of nesting was found by him, and he did not, apparently, realize that the birds he saw were waynei. In 1932 Drs. W. R. McIlwaine and J. J. Murray visited Dismal Swamp on May 23-26, and “found Wayne’s warblers rather common.” From Murray (1932) we find that they “heard two singing males on May 23rd as we came down the Washington Ditch to the Lake; two males singing on the 24th near the entrance to the Feeder Ditch * * * and six males on the 26th.” They also found two family parties of adults feeding small birds on the 24th. One of these parties was near the mouth of the Feeder Ditch; the other a half mile up the Jericho Ditch from the Lake (Drummond). * * * The young birds were out of the nest and could fly well. They looked like big bumble-bees buzzing across from one tree to another; staying rather high up. The adults ranged low in gathering food, both male and female feeding the young birds.
