216. Dendroica palmarum hypochrysea, Yellow Palm 

 Warbler. This is an abundant summer resident, in the Mer 

 Bleue only so far as is known, but probably also in other similar 

 localities in the district. I have taken them June 3rd, 1904; 

 June 13th, 1909; August 5th, 1910, when the young were full- 

 grown. They probably arrive here before palmarum, as a nest 

 with four eggs was found as early as May 23rd (1908). The song 

 is Hke that of the Chipping Sparrow. 



217. Seiurus aurocapillus. Oven-bird. A common migrant 

 and summer resident. In deciduous woods, as Beechwood, 

 Beaver Meadow, etc., one or two may nearly always be heard. 

 Extreme dates of stay: May 6th to September 19th. 



218. Seiurus noveboracensis, Water-Thrush. A moderately 

 common migrant and summer resident. At the pools in the 

 waterfront, west of Eddy's mills, Hull, several pairs may be 

 seen and heard throughout the summer, as also on the eastern 

 side of Beaver Meadow. Extreme dates: May 8th to September 

 6th. One of their loud, liquid songs may be represented, 

 whitla xvhit-cher, ivatch watch ivatch watch. 



219. Oporornis agilis, Connecticut Warbler. A rare migrant. 

 I have seen it twice at a range of 5-10 feet, at Rockcliffe Park 

 May 5th, 1906, and at High Falls, Quebec, October 3rd, 1907. 



220. Oporornis Philadelphia, Mourning Warbler. A rather 

 rare migrant and breeder. It is a swamp-loving species ; where 

 cedar, spruce and alder bushes, especially the last, are found 

 growing in or near water, it must be looked for. A pair usually 

 breeds in each of the following places: alders near Slattery's 

 slaughter house, Ottawa East; Dow's Swamp; alder fringe in 

 Beaver Meadow, and west of Blueberry Point. Time of stay: 

 May 19th to September 9th. 



221. Geothlypis trichas, Maryland Yellow-throat. A very 

 common migrant and summer resident. In willow, alder and 

 cat -tail swamps, down to the smallest, it is usually to be seen. 

 Its call, whitchedy, whitchedy, whitchedy, announces its presence 

 long before one sees the bird. It has also quite a repertoire of 

 other songs. By June 7th its nest with three eggs has been 

 found. It first arrives May 5th; our locally breeding birds go 

 by August 1st, but their place is soon taken by migrants from 

 farther north, of which the last is seen September 25th. 



222. Wilsonia pulsilla, Wilson's Warbler. A moderately 

 common migrant only, not breeder, although it may yet be 

 found as such. It is one of the later comers in May, not arriving 

 before the 15th. As late as June 2nd, 1907, they were abundant 

 at Ottawa East. The last have been seen September 15th. The 

 song, rarely heard, is, tsit sit sit dreer idididee.
