71. Dendroica caerulescens. Black-throated Blue Warbler. — 1 

 heard the first Black-throated Blue Warbler on the crest of the Cowee 

 Mountains, but at the tune supposed it to be a belated migrant. On the 

 following day, however, others were met with at Cullasaja Falls, and 

 along the road between that point and Highlands many were seen or 

 heard. In the neighborhood of Highlands they were everywhere numer- 

 ous, and in the extensive rhododendron swamps, literally swarming 

 and evidently settled for the season, if not actually breeding. Mr. Boyn- 

 ton tells me that he regularly hears them singing in these swamps through 

 June and July, but he has never found the nest. On the Black Mountains 

 they were scarcely less numerous in belts of rhododendrons bordering 

 streams at between 3200 and 4500 feet, but curiously enough none were 

 seen above the latter elevation, although the balsam forests on the upper 

 slopes of these mountains would seem to furnish congenial haunts.
