TAVERNER AND SWALES ON POINT PELEE BIRDS. 95 



weed before spoken of. In 1907 two were taken August 27, one the 

 30th, and another the 31st. The last one was observed September 

 2. Seeing that the migrations were late this year, it is more than 

 likely that the Mourning Warbler normally passes through about 

 the third week in August, and it is one of the earliest migrants to 

 be looked for in fall. 



The juvenile fall Mourning Warbler closely resembles the young 

 Connecticut, but can be readily distinguished from it by the yellow 

 and greyish suffusion over the throat and foreneck. 



180. *Geot1ilypis trichas brachidactyla Northern Yellow-throat. 



The Yellow-throat has been common on all May visits, but of 

 peculiar occurrence in fall. In 1905 six were observed on the first 

 day of our arrival, September 4, and then no more until the 14th, 

 when they became common. In 1906, they were very common the 

 first three days of September, but on our return trip they were far 

 less abundant, and but two or three were noted the 15th, 17th, 18th, 

 and six the 19th. One was still present this year as late as Octobei 

 14. From August 24 to September 6, 1907, none were observed at 

 all. The only obvious explanation of this erratic procedure is that 

 either few or no Yellow-throats breed on the Point, or else that tlw 

 summer residents depart early in the fall, and that at the time of 

 our arrival and stay in 1907 the migrants had not yet arrived. This 

 species remains with us usually until well into October, but all our 

 fall data at Pelee points to the conclusion that there is a strong mi- 

 grational movement among them, beginning the latter part of 

 August. 



181. *Icteria virens. Yellow-breasted Chat. 



Point Pelee is the only locality in Canada where the Yellow- 

 breasted Chat is any more than a rare accidental straggler. How 

 far its range here extends inland we are unable to state, as our 

 work has never extended inland beyond the base of the Point. Tl-c 

 first observation on the Chat in Canada was likely made here, as 

 Dr. Brodie says of his July trip of 1879, "A specimen recently 

 killed was brought to me by school children. The bird had ilowu 

 in through an open window of the school and was killed against th 

 glass in an opposite window." June 6, 1884, Saunders secured sp- 

 uiens as recorded by Macoun in his Birds of Canada. May 13, l 

 we found several pairs in a waste clearing, grown up to hushes. 

 near the base of the Point, and secured one and the next clay 

 another by the road along the edge of the marsh on the east side. 

 May 20-21, 1906, two and one were observed or taken beyond Gard- 

 ner's place on the respective days. May 31, 1907, three more \\MV 

 observed in about the same locality. Swales and Wallace saw one 

 May 3, 1908. This is a species that departs early in the season and
