CONTOPUS BOREALIS : OLIVE-SIDED FLYCATCHER. 27 



writes me that he took a male at Suffield, Conn., 

 Aug. 8, 1874. This is strong evidence of their breed- 

 ing in the hills about that portion of the state, for mi- 

 grants would hardly appear in Connecticut during the 

 first oi August." (B. Conn., 1877, p. 53. See also his 

 notes in Am. Nat., vii, 1873, p. 750, and viii, 1874, p. 309; 

 also R. Deane's, ibid, p. 308.) The Connecticut record 

 being thus so meagre, the time of the entry of this 

 migratory bird into New England cannot be given with 

 precision. It is one of the later arrivals, however, ap- 

 parently not reaching Massachusetts before the second 

 week in May, and leaving its summer resorts rather early 

 in September. In that state, different observers have 

 called it a " rare summer resident," a " rather uncommon 

 summer resident," "neither rare nor common," and 

 "quite common," according to different localities and 

 circumstances of observation. It is marked as "quite 

 common and breeding " at Umbagog Lake, in Maine, by 

 Messrs. Maynard and Brewster, and Mr. G. A. Boardman 

 speaks of its " abundance " some seasons in the vicinity of 

 Calais, in the latter state. We also have records to cor- 

 responding effect from Vermont and New Hampshire. 



The Olive-sided Flycatcher is confined to no particu- 

 lar kind of ground, but may be observed in orchards and 

 gardens, or groves of evergreen trees, as well as in the 

 depths of pine forests. In Massachusetts, it is partial 

 to pitch pine groves, especially during the breeding 

 season. Wherever found it is likely to become a con- 

 spicuous object from its habit of perching in exposed 

 situations upon the ends of dead limbs, or blasted tree- 

 tops, whence it utters its loud characteristic notes and 

 makes its spirited sallies after passing insects, return- 

 ing to the same post of observation. Nesting is essen-
