summer, and thus betrays its presence. Time of stay: 6th of 

 May to 22nd of September. 



197. Lanivireo flavijrons, Yellow-throated Vireo. A rare 

 summer resident. In six years I have seen four here, two of 

 which were on King's Mountain, July 20th, 1905. They arrive 

 about May 11th. 



198. Lanivireo solitarius, Blue-headed Vireo. A moderately 

 common migrant, but rare breeder. They arrive May 7th, and 

 the latest date for them is September 1 Ith (1909). On May 28th 

 1898, a nest was found at Chelsea, and on August 21st, 1907, I 

 saw fully grown young on Kettle Island. 



MNIOTILTID/E WOOD WARBLERS. 



199. Mniotilta varia. Black and White Warbler. A common 

 migrant and moderately common breeder. This frequenter of 

 the more open, deciduous second-growth woods arrives from 

 .April 28th to May 13th; the last are seen September 21st. 



Breeds in Beaver Meadow, Blueberry Point and similar places. 



200. Vermivora ruhricapilla. Nashville Warbler. A moder- 

 ately common migrant and breeder, but only in its chosen 

 haunts, viz., the stands of small poplar and birch in low, wet 

 places in woods. In such a spot at Blueberry Point a pair or 

 two can be found any day in summer. More common in the 

 poplar stands around the Mer Bleue. They begin to arrive May 

 7th, reaching their climax in numbers May 15th. On July 13th, 

 1881, a nest with four eggs was found at Dow's Swamp. The 

 latest date for them is September 25th. 



201. Vermivora celaia, Orange-crowned Warbler. An ex- 

 tremely rare migrant. On September 27th, 1885, one was taken 

 by Mr. E. White near the eastern end of the city. This is the 

 only record. 



202. Vermivora peregrina, Tennessee Warbler. A rare mi- 

 grant ; will probably be found breeding in some of the tamarack 

 swamps in the northern part of the district. It passes through 

 Ottawa from May 12th to June 7th (1907), at which latter date 

 Messrs. Chapman and Fuertes saw some in Major's Hill Park. 

 The last are seen September 30th. Its song is a high, sharp 

 tsip, tsip, tsip, pit it it itereeeee. 



203. Compsothlypis americana usnec, Northern Parula 

 Warbler. A moderately common migrant and rarer breeder. 

 Its habitat is tall deciduous trees, as on the west side of Beaver 

 Meadow, where it may be found in summer. It begins to arrive 

 May 7th, reaching its climax May 20th to 23rd. The last are 

 seen September 13th. The song is a somewhat scratchy, dreer, 

 dreer, dreer, last note highest and loudest ; also a trill like 

 re-e-e-e-e-e.
