Black-throated Green Warbler (Dendroica virens). Tol- 

 erably common and breeding in the spruce woods that flank the rivers. 

 First observed about May 16. 



Oven Bird (Seinrus aurocapillus). Breeds at Edmonton along 

 the timbered river banks. Arrives about May 15, common by the 24th. 



Grinnell Water-Thrush (Seiurus noveboracensis notabilis). 

 This sub-species was noted as far west as Edmonton, in 1906, by 

 Mr. Atkinson. 



Mourning Warbler (Oporornis Philadelphia). Mr. Spread- 

 borough collected a male specimen on June 4, 1897. 



Maryland Yellow-throat (Geothlypis trichas). Common 

 summer resident. Arrives about May 24. The form inhabitating 

 this region probably referable to the Northern Yellow-Throat G. t. 

 brachidactyla. 



Wilson Warbler (Wilsonia pusilla). Mr. Spreadborough first 

 observed this species at Edmonton on May 29, 1897. A few pairs 

 remained to breed. 



Canadian Warbler {Wilsonia canadensis). Mr. Spreadbor- 

 ough did not observe this species anywhere west of Manitoba, except 

 at Edmonton, where he took a male specimen on May 29, 1897. 



American Redstart (Setophaga ruticilla). Tolerably common. 

 Arrives the latter end of May. Mr. Spreadborough found them nest- 

 ing in willow thickets along the streams. 



American Pipit (Anthns p ensilv aniens) . Mr. Spreadborough 

 found this species common at Edmonton from April 27 to May 10, 

 1897. 



Catbird (Galeoscoptes carolinensis) . Common summer resi- 

 dent. Returns about May 24. 



House Wren (Troglodytes aedon). Common summer resident. 

 Arrives about May 11. The form at Edmonton is referable to the 

 sub-specific one T. a. parkmanii. 



Marsh Wren (Telmatodytes palustris). A very common sum- 

 mer resident about the sloughs. The nest is completed and the eggs 

 laid by June 5. They have a peculiar habit of building several 

 dummy nests in addition to the genuine one. I once found seven 

 perfectly finished nests within a radius of twenty-five yards. Only 

 one contained eggs, and only one pair of wrens frequented that 

 vicinity. The sub-specific form at Edmonton is placed under /. p. 

 iliacus. 



White-breasted Nuthatch (Sitta carolinensis). Mr. Atkin- 

 son records the species as far west as Edmonton in 1906, the reference 

 being referred to S. c. nelsoni. 



Red-breasted Nuthatch (Sitta canadensis). Mr. Spreadbor- 

 ough found the species tolerably common at Edmonton in the spruce 

 woods, June 12, 1897.
