AMtmCAX AVARlJLEr>'S. 37 



V 



1he month, I saw a few at Fairliaven, Massachusetts, on 

 Octoljer iS, 19C0, and on the 24 they were commcn aloii"- the 

 Raritan and Delaware Canal, in New Jersey, but I did not see 

 them further south a few days Inter. They winter in South 

 America. 



Special Notes ox the Xoxiiierx Mioii.vtiov. The noithward mi- 

 gration of this warbler, as I hav3 traced it, is exceedingly ir.tcrcstirg. Mhi'c 

 mailing dowr. the coast of Andros Island, Bahamas, about eight o'clock in the 

 morning of April 27, 1884, from Deep Crttk, ^\hcn seme five miles fre.m lard, 

 o!FHigh Point, we began to observe flocks of warblers. They were mostlv Black- 

 polls, and consisted of from three or four individuals to a hujidied, or even more. 

 Some flew c!ose to the surface of the water, but the usual height v,as about ten 

 feet from it ; none were over twenty feet high. The birds were coming from a 

 south-easterly direction, and the flocks appeared at quite frequent intervals. As 

 the day advanced these flights inceased in numbers, and when we landed in the 

 afternoon on some small keys, near the south end of Andros, we found them 

 covered with warblers, mostly Black-polls, which were then constantly arrivino- 

 and departing. The night before this large flight we had thunder showers, and 

 in the morning a light v.'ind from the north which shortly increased, and bv two 

 o'clock in the afternoon was blowing a stiff breeze. The next day the flight con- 

 tinued with the Black-polls as abundant as they were the day before ; the num- 

 ber seen being very great, and consisted of both sexes. On the third day, April 

 29, there were a few only remaining on the key : the flight was over, havin'T 

 lasted two days. 



On April 20, 1893, I saw a single male Elaek-poll on the island of Eleu- 

 thera, a little more than a hundred miles north of the point on y\ndros where the 

 foregoing observations were made, and, what is more note- worthy in the present 

 case, some fifty miles to the eastward. Black -polls were abundant there by the 

 second of May, and these were mostly males. On May 5 they were common on 

 Salt and Athel's Keys, just north of New Providence, and on May 6 were abund- 

 ant about Nassau. 



The only Florida record of my own that I can find for the Black-poll is of 

 a single specimen, taken at Miami, on April 16, 1871, vihich must have been a 

 straggler, as the date was exceptionally early. 



Black-polls an ive in Massachusetts about INIay 10, are common ty the lo, 

 and stragglers are founel at least as late as June 10. They arrive on their breed- 

 ing grounds from June 5 to 15. 



With the above data in hand, it is possible to trace this species of warbler 

 from it's winter resort to it's northern breeding ground, and give the approximate
