Gkographical range: Eastern North America; north to the sonthern portions of 

 Labrador and the Northeast Territory; west to Manitoba and Minnesota; south in 

 winter through eastern Mexico and Central America to Fanama. Casually to Greenland. 



The Yellow-bellied Flycatcher is a summer resident in the northern forest 

 and moxnitain regions of 'the United States, and liveeds from Massachusetts 

 and New York northward throuo^h the maritime provim'es of the Dominion of 

 Canada to southern Labrador and the Northeast Territory, where Prof. John 

 Macoun reports this species as common about Lake Mistassinni, in latitude 51°, 

 lono-itude 72° and 73°, and it probably passes beyond this point. It has also 

 been recorded as breeding regularly in the Alleghany Mountains, in Pennsyl- 

 vania, and probably will yet be found as a rare summer resident at points 

 considerably farther south, as in the Smoky Mountains of North Carolina, etc. 

 In the west it is recorded as a regular summer resident in eastern Manitoba and 

 Minnesota, and probably breeds also in northern Wisconsin. It passes south in 

 winter through eastern Mexico and Central America to Panama. Several 

 specimens have been recorded from Greenland. 



Within the limits of the United States the Yellow-belhed Flycatcher seems 

 to be fairly conunon in the northern New England States, while in the Adiron- 

 dacks and CatskiUs, in New York, it must be considered as rather rare. Tins 

 apparent rarity is due perhaps more to its unobtrusive habits, its retiring nature, 

 and favorite haunts during the breeding season; as it frequents the dark, moist 

 recesses of the forests, which at this time of the year abound with bitmg msect 

 pests of all kinds, and which for that reason are usually shunned by all but 

 truly enthusiastic ornithologists and oologists. As far as my observations go 

 (and they are rather limited) I consider this species the most silent and retmng 

 of all our Flycatchers, and, although it may be nuich more common in suitable 

 localities during the breeding season than it appears to be, it is but rarely seen 

 at this time unless accidentally flushed from its nest. In the Adirondack moun- 

 tains where I have met with it, it was observed only in primitive mixed and 

 rathe'r open woods, where the ground was thickly strewn with decaying, moss- 

 covered logs and boles, and almost constantly shaded from the rays of the sun. 

 The most gloomy-looking places, fairly reeking with moisture, where nearly 

 every inch of ground is covered with a luxuriant carpet of spagnum moss, into 

 which one sinks several inches at every step, regions swarming with mosquitoes 

 and black flies, are the localities that seem to constitute theii- favorite summer 

 haunts, and it is not surprising to me that the eggs of this Flycatcher are still
