migrant. Arrives from April 26 to May 3rd, remaining until the middle of 

 May. Returns again in early September, remaining throughout the month. 



113. Helminthophila peregrina (W/ils.) Tennessee Warbler. — Fairly 

 abundant during the fall migration, rare in the spring. Arrives about May 

 10th, remaining as late as the 20th. In September it appears again, lingering 

 until early October. In the fall of 1893 this was a very abundant warbler. 



114. Dendroica tigrina (Gmel.) Cape May Warbler. — A rare migrant, 

 May and September. I believe that this warbler is more often observed in 

 autumn. Mr. Purdy has never observed it at Plymouth. In 1903 I observed 

 but one bird, a male, on May 12th, 



115. Dendroica aestiva (Gmel.) Yellow Warbler. — An abundant sum- 

 mer resident. A uniform bird in its dates of arrival as the following dem- 

 onstrates: April 27, 1889;- May 3, 1890; April 28, 1891; April 29, 1892; May 

 1, 1893; April 28, 1894; April 25, 1895; April 18, 1896; April 26, 

 1897; April 25, 1899; April 29, 1900; May 2, 1901; April 26, 1902; April 

 29, 1903. The bulk of the species have departed by the first of September. 



116. Dendroica caerulescens (Gmel.) Black-throated Blue Warbler. — 

 A fairly common migrant. Arrives from May 3rd, remaining as late as 

 the 22nd in 1901, and the 17th in 1903. Reappears in early September, re- 

 maining as late as October 4th, in 1893. 



117. Dendroica coronata (Linn.) Myrtle Warbler. — One of the most 

 abundant migratory warblers. I have seen it as early as April 11, (1891), 

 and as late as May 11, (1902). Returning in late September, remains well 

 through October. In 1893 I observed several November 25th, an unusually 

 late date. 



118. Dendroica maculosa (Gmel.) Magnolia Warbler. — Abundant mi- 

 grant. Arrives in the first week of May, remaining about ten days. In 

 1903 I saw one male May 24. Returns again September 1st, lingering until 

 the 20th, occasionally later — in 1902, October 1st. 



119. Dendroica rara (Wils.) Cerulean Warbler. — A common summer 

 resident. Arrived May 3rd, 1891, 1896; May 7, 1899; May 8, 1897. Departs 

 September 15-10. TTiis species has been found breeding by several parties 

 around Detroit. 



120. Dendroica pensylvanica (Linn.) Chestnut-sided Warbler. — A fairly 

 abundant summer resident. Arrives about May 6th, remaining well into 

 September. 



121. Dendroica castanea (Wils.) Bay-breasted Warbler. — Not a com- 

 mon migrant. Arrives May 6-lOth, remaining but a few days. Again in 

 September. In fall it is doubtless confused with D. striata, and as a result 

 not recorded. I was able to secure several on May 8th, 15th, and 20th, 1904. 



122. Dendroica striata (Forst.) Blackpoll Warbler. — Common during 

 the migrations, much more so in fall than in spring. Arrives May 10-15, 

 and apparently lingers but a few days. Returns again around September 

 10th, and remains through the first; week of October — a few occasionally 

 are noted even later. 



123. Dendroica hlackhurniae (Gmel.) Blackburnian Warbler. — Fairly
