OLIVE-SIDED FLY-CATCHER. 



(Muscicapa Cooperi, Nuttall and Cooper, Man. Orn. i. p. 282, 

 Tyrannus borcalis, Swainson, North. Zool. ii. p. 141. pi. 35.) 



This bird appears to have been discovered in the fur 

 countries about the same time as in the United States. 

 According to Dr. Richardson, the specimen, figured so spi- 

 ritedly in the Northern Zoology of Canada, was shot on the 

 banks of the Saskatchewan as it was flying near the ground. 



In 1832, about the middle of June the same pair ap- 

 parently, had again taken possession of a small Juniper 

 not more than 300 yards from the tree they had occupied 

 the preceding year, about 14 or 15 feet up which they had 

 fixed their thin twiggy nest as in the preceding year. It 

 contained 4 eggs on which the female had commenced sit- 

 ting ; these, except in their superior size, were precisely 

 similar with those of the Wood Pewee, yellowish-cream color, 

 with dark brown, and lavender purple spots, rather thinly 

 dispersed. Being unfortunate enough to shake out the two 

 eggs I intended to leave in the nest, the pair had to com- 

 mence their labors of preparing for a progeny anew ; and a 

 few days after a second nest was made in another Virginian 

 Juniper at a very short distance from the preceding. 

 The present year, however, they did not return to their ac- 

 customed retreat, and no individual was seen in this vicin- 

 ity. In all places it appears, in fact, a scarce and widely 

 dispersed species.
