resident at Avenue Manitoba, arriving about the middle of May 
and leaving about Sept. 7th. (Vorman Criddle.) The writer paid a 
visit to the swamp south of Carberry in June, 1896, and had the 
good fortune to secure a nest on the outskirts of the bog and 
almost on a level with the water. It contained one egg and three 
very young birds; there seemed no scarcity of excited birds as I 
floundered through the bog. 
679. Mourning Warbler. 
Geothlypis philadelphia (Wits.) BAIRD. 1858. 
One specimen obtained at the Fiskingwes in 1846, another at 
Julianshaab in 1853. (Avct. Man.) Rare about Halifax, but 
common in the interior of Nova Scotia as a summer resident. 
(Downs.) «\pparently rare on Prince Edward Island, though a 
few were found at Sourisin the bushy edges of dry fields, adjoin- 
ing woods. (Dwight.) A rare summer resident at St. John, N.B. 
(Chamberlain.) Not uncommon in the upper part of the Resti- 
gouche valley, N.B. (Brittain & Cox.) 
A rare species around Quebec; taken at Beauport. (Dvzonne.) 
Transient and scarce visitant around Montreal. Has been shot 
at Outremont and Hochelaga. (MWentle.) A moderately common 
summer resident around Ottawa. (Ottawa Naturalist, Vol. V.) 
A few of these birds breed in the county of Leeds, Ont. I met 
with the nest on 31st May, 1893, containing four eggs much resem- 
bling those of the yellow-throat. A peculiarity of the nest, and 
one I believe generally observed, is that it is lined with black 
fibres and rootlets and not as the yellow-throat with fine grass and 
hair. This bird is a common species during migrations on the 
Magdalen Islands and probably breeds there also. (Rev. C. J. 
Young.) A fairly common resident in Parry Sound and Muskoka 
districts. It is one of the latest arrivalsin spring. (/. H. Fleming.) 
Quite common along the Parry Seund Railway in Algonquin 
Park, Ont., always in dry thickets. (Spreadborough.) A not un- 
common summer resident all over western Ontario. (W. &. 
Saunders.) Uncommon; but perhaps considered more so than it 
really is as the bird is such an adept at keeping out of sight. 
Still if one knows their haunts and reaches them about 18th to 
24th May he may see a few if he will only sit down close to the 
ground and keep quiet; though on walking through one of their 
favourite retreats one can be almost sure to hear the warning or
