1904J Observations on rare birds met with in 1904. 139 



beech, elm, pine or hemlock, in all of which trees I have seen the 

 nest. 



The red-tailed-hawk is quite rare in eastern Ontario, I have 

 no knowledg-e of its nesting along- the St. Lawrence though I have 

 seen the bird. In the rougher parts of the country northward a 

 few pairs do so, and this year a nest was located in the township 

 of Olden, in a high black ash, which on May 21st contained two 

 eggs, highly incubated. 



The vicinity of Sharbot Lake is the summer home of many 

 warblers, and some of the fly-catchers. Of the latter I have 

 observed the king bird, the great-crested, the olive-sided, the wood 

 peewee, the phoebe, Traill's flv-catcher (Var. alnorum), and the 

 least fly-catcher. Of the former, the yellow warbler, the myrtle 

 warbler, the magnolia warbler, the black-throated green, the 

 black-throated blue, the blackburnian, the palm warbler, the 

 Maryland yellow-throat, the oven bird, the water thrush, the 

 Canadian warbler, and the red-start, along with two or three 

 varieties, that I could not identify, are frequent. All the aboye 

 breed, and during the past season, I saw nests of magnolia, June 

 6th, in a small black spruce, containing four young ones just 

 hatched ; on the same date a black-throated-blue warbler's in a 

 maple sapling, with two fresh eggs ; also a red-start's with four 

 eggs ; and on May 27th, a water-thrush's just ready for eggs. 

 But none of these birds is rare compared with the olive-sided 

 fly-catcher, which I located on the 6th June, in the same black 

 spruce swamp, where I found the magnolia warbler. Li the open 

 spaces, patches of arctis hn ickle-berry grow round the scattered 

 spruces, and amid the springy moss, were the largest pitcher- 

 plants then in flower. I had ever seen. A short distance away, 

 outside a belt of spruces were many plants of the beautiful lady's 

 slipper, Cypripedium acaule ; and not far off the bright waters of 

 Sharbot Lake. In a black spruce eighteen feet high, the olive- 

 sided fl_\-catcher had established his home. The nest was built on 

 a horizontal bough thirteen feet from the ground, and on June 6th, 

 contained two eggs. Later, in the swamp 0.1 June 23rd, I found 

 another of these nests containing three eggs, incubation com- 

 menced. It probably belonged to the simj pair of birds, as it 

 was no* more than fifty yards from the first nest, but was built in
