SUPPLEMENT TO BIRDS OF ESSEX COUNTY 1 67 



298 [679] Oporornis Philadelphia (Wils.). 



Mourning Warbler. 

 Very rare transient visitor. May 20 to June 3 ; September. 



I have a number of records for this bird in the latter part of May. On May 

 31, 1913, one visited my " forest " at Ipswich. The June 3 date is of a bird seen 

 in Ipsvi'ich. 



In 1912, Mr. Damsell records two instances at Amesbury, both on May 30. 



299 [68t] Geothlypis trichas trichas (Linn.). 



Maryland Yellow-throat. 

 Abundant summer resident. May 2 to October 29 (Deceml)er 5, 6). 

 Eggs: May 24 to June 13. 



The December 5 record was of a bird seen by Mr. George M. Bubier at 

 Nahant, in 1909. 



Early in the morning of May 30, 1919, a Maryland Yellow-throat in the 

 plumage of the female, entered my lean-to in my " forest "' at Ipswich and flew 

 about distractedly trying to get out, alighting several times on my pillow. At 

 last, when I pushed aside the netting it escaped, uttered a few scolding notes in a 

 tree near by and then, much to my surprise, burst into a very imperfect but quite 

 recognizable song of the species. 



300 [683] Icteria virens virens (Linn.). 



Yellow-breasted Chat. 

 Not uncommon local summer resident. May 10 to October 27. 

 Eggs: May 30 to June 18. 



From Mr. Damsell's records it is learned that one was shot at Amesbury on 

 September 30, 1882. Dr. Allen remarks : " There is little probability that it had 

 bred in the vicinity but may have wandered from the breeding stations in the 

 southern part of the County."^ 



On June 28, 1908, I discovered a Chat in a tangle of bayberries, wild roses, 

 apples, cherries, and sumach on the north side of Sagamore Hill in Ipswich and
