^24 BrimLRY. Nesting of t$e Yelloiv-t lima ted Warbler. [October 



taken a nest yet when the male was not singing near by, 

 though we have on three occasions observed the female come to 

 the nest early in the morning just before we took it and so pre- 

 sume she has to feed herself as well as do all the work. This 

 Warbler is the closest sitter I am acquainted with, never leaving 

 the nest till the limb it is built on is jarred, and in a large majority 

 of cases, not till the nest itself is touched. When she does con- 

 clude to quit she slips out of the nest and flutters vertically down- 

 ward some six feet or more, but makes no pretense of a broken 

 wing or any other affliction. The set is usually four, occasion- 

 ally three. When one set is taken, the female goes to work, 

 builds another nest, and lays another set. 



The nest is very hard to find, in fact the only way to find one 

 is to watch a pair of birds day after day until at last the female is 

 detected building, and the nest located. As seems to be the case 

 generally here with Pine Warblers and Gnatcatchers, it is easier 

 to detect the Yellow-throated Warbler building when it first com- 

 mences than later on when it is putting in the finishing touches. 



The following list of all the nests we have found here will give 

 a better idea of several details than any amount of general de- 

 scription. 



1. Nest found April 25, iSSS, about one third built in a large old field 

 pine, the female only building. This was in a narrow strip of good- 

 sized pines adjoining a large tract of woods. The nest was taken on 

 May 11, and contained only one fresh egg. The nest was 65 feet high, 

 and 12 feet from the trunk, and was larger and deeper than a Pine War- 

 bler's, but the rim was thinner and more ragged, the nest was composed of 

 grape-vine bark, horsehair, and a great quantity of white chicken feathers. 

 The nest was not built on a limb, but attached by the sides and bottom to 

 a number of small twigs, thus differing in situation, as well as in con- 

 struction, from any other taken so far. 



2. Nest found April 25, 1SS9, apparently just finished, but with no 

 eggs. Took set of four from this nest on May 4, flushing the female from 

 the nest on jarring the limb, eggs fresh. The nest was 20 feet high, 7 

 feet from the trunk, on a horizontal limb of the pine, and also laced to 

 small twigs. The nest was much like a Pine Warbler's, but smaller and 

 grayer, lacking the grape-vine bark of the latter. The nest was in a 

 fifty-acre tract of pines where most of this year's nests were found. 



3. Nest found just commenced on April 5, 1890, 42 feet, built on fork 

 of pine limb some eight feet from the trunk. The set of four fresh eggs 

 was taken April 25. The bird came to the nest while my brother was put- 

 ting his climbers on. The nest was much like a Pine Warbler's, but with
