lSgo.J Brimley, Nesting of the Yclloiv-throated Warbler. ^2C 



no grapevine bark, but instead some bark of the trumpet-vine, and heavily 

 lined with feathers; the rim was quite thin and loose, otherwise the 

 nest was solid enough. 



4. April 29, I found the same pair re-building, this time on a pine 

 limb some 47 feet high and four or five feet from the trunk. On May 12 we 

 took our second set of four from this pair, the eggs containing small em- 

 bryos. The pine was tall and slim, and we had to stay it with ropes 

 while taking the nest. The female stayed on the nest till it was touched. 

 Nest similar to the preceding two. 



5. May 15, I found this pair again re-building in a pine near where 

 their first nest was (the second nest having been some 200 yards east of 

 the first one), the pine being even taller and thinner than before. The 

 nest was 58 feet high and 6 feet from the trunk, and the pine swayed 

 frightfully, although stayed with ropes, when we took our third set of four 

 on May 26. This nest was quite small, otherwise like the others. 



6. On May 28 I started for the fourth time to look up this pair and 

 duly found them, in no way discouraged, again building, this time near 

 the second nest and in a respectable sort of pine, 44 feet high and four or 

 five from the trunk. On June 7 we took our fourth set of four from this 

 pair, and I think we were satisfied. 



7. Found a second pair of birds building a well-built nest on a good- 

 sized limb of a large pine, 42 feet high and about seven from the trunk. 

 On April 22, 1890, we took a set of four fresh eggs from this nest. The 

 nest was composed of weed stems, grass stems, and caterpillar silk, and 

 heavily lined with horsehair. 



8. On May 8, 1890, we found and again took a set of four from this 

 pair. The nest was 38 feet high and some ten feet from the trunk, and 

 was built and almost hidden in the lateral fork of a large limb. We found 

 the nest by watching the bird go to it after feeding. This nest was made 

 of the stems and leaves of a gray weed known as rabbit tobacco, pieces of 

 cotton, cocoon silk, fine grass and horsehair, and weed stems, and was 

 heavily lined with horsehair. The eggs contained small embryos. 



9. April 24, I found a third pair of birds building a well-built nest in a 

 medium-sized pine, 43 feet high and four feet from trunk. Took four eggs, 

 slightly incubated, from it on May 3. The bird went to the nest while 

 we were preparing to take it. This nest was very large, with very thick, 

 strong walls made very largely of rabbit tobacco, the outside almost en- 

 tirely of it, and was lined with feathers and horsehair. The nest, super- 

 ficially, reminded one more of that of the Prairie Warbler, a bird which 

 uses rabbit tobacco a great deal, but was much larger and thicker. 



10. May 2, I found a nest just started by a fourth pair on a pine limb 44 

 feet high, some five or six from the trunk. The female was building in a 

 desultory sort of way. We took a set of four fresh eggs on May 8. This 

 nest was very small and only scantily lined with feathers, the lining be- 

 ing so thin that the eggs would have fallen through in one place if there 

 had been nothing underneath. 



11. I found this last pair re-building May 19, 43 feet from ground and
