40 Bulletin ok the 



abundant migrant. 1 have seen it from May 3, (1903) until May 21, (1899). 

 Again in September, in 189:5, remaining until the 30th. 



124. Dcndroica dotiiinica albilora (Ridg.) Sycamore Warbler. — From 

 personal observation I know little of this warbler. Walter C. Wood secured 

 a pair in July, 1899, and is of the opinion that they were breeding. {Auk, 

 xvii, 1900, p. 391). Mr. Purdy has never met with it at Plymouth. 



12.'). Dcndroica vircns (Gmel.) Black-throated Green Warbler. — One of 

 the abundant migratory warblers from May 1st to as late as the 20th, gen- 

 erally the bulk are gone by the 10th. The re^iurn movement commences 

 around the first of September, a few remaining as late as October 7th. 



12G. Dcndroica vigorsii (Aud.) Pine Warbler. — I have observed this 

 bird but rarely in the May migrations, never in fall. Mr. Purdy says ''an 

 occasional migrant." Careful, and extended observation is needed on the 

 local warblers by competent observers before the abundance and extent of 

 migrations can be definitely stated. 



127. Dcndroica palmarum (Gmel.) Palm Warbler. — Fairly abundant mi- 

 grant, apparently more so in spring than in fall. I have notfed it from late 

 .^pril until May 4th. Purdy has found it fairly abundant at Plymouth. Ar- 

 rived May 4, 1902; May 2, 1903; May 1, 1904. 



128. Dcndroica discolor (Vieill.) Prairie Warbler. — 1 have never ob- 

 served this personally, and J. Claire Wood and J. B. Purdy have similar 

 experiences. W. A. Davidson states {Oologist, xii, p. 53) that he found it 

 nesting near Detroit May 27, 1894, but the bird was not secured. 



129. Sciurns aurocapillus (Linn.) Ovenbird. — A common summer resi- 

 dent. Arrives April 24th, in 1891, to May 7th, in 1901. Departs during the 

 latter part of September. Octo'ber 5th, in 1893, is the latest autumnal record 

 I have. 



130. Sciurus novcboraccnsis (Gmel.) Water Thrush. — 1 have not found 

 this a common bird except during the period of its arrival. It reaches here 

 during the first week in May, remaining until late September. In 1889 I 

 noticed one October 8th. 



131. Sciurus motacilla (Vieill.) Louisiana Water Thrush. — Fairly com- 

 mon species in spring, reaching here a little in advance of S. novcboraccnsis 

 — April 20th — May 1st. Of late years I have found this to be more common, 

 and have located a number of pairs. The song is exceptionally sweet, wild, 

 and ringing, and the birds shy. Several nests have been found by local 

 observers near Detroit. 



132. Gcothlypis Philadelphia (Wils.) Mourning Warbler. — Fairly abun- 

 dant warbler during the migrations in May. J. Claire Wood met with a pair 

 July 28, 1903, which might indicate tha* the birds had been breeding. I 

 have not seen it in fall. 



133. Gcothlypis trichas brachidactyla (Swain) Northern Yellow-throat. 

 — Abundant summer resident. Arrives from the 4th to the 10th of May. 

 Departs in late September. In 1901 T observed several October 8th. 



134. Ictcria vircns (Linn.) Yellow-breasted Chat. — Locally a rare sum- 

 mer resident. I have never met with it personally, and know of but two
