SUMMER BIRDS.

species ol Water Thrush in this region. Reference to its occur- 
rence along the Neversink is also made by the same writer. ■}* 
The song ol a Water Thrush was indistinctly heard at a swampy 
place in the mountains, beyond the source of Esopus Creek, which 
was very probably that of the small-billed species. 
This Water Thrush is doubtless a regular summer resident at suit- 
able localities. 
Geothlypis Philadelphia (Wils.) Baird. Mourning Warbler. 
One of the most characteristic birds of parts of the Catskills, in- 
habiting, chiefly, old cleared or burned-over land grown up with 
weeds, briers, shrubbery, and saplings. Always conspicuously com- 
ponent of these mixed growths are the Wild Red Cherry ( Primus 
Pennsylvania a) and the Great Willow Herb {Epilobium spicatum Lam.) 
but the breeding- season of the Mourning Warbler must fall between 
the times when the white flower-clusters of the former and the brill- 
iant crimson spikes of the latter plant beautify the waste tracts which 
are its home. 
Few Mourning Warblers were noticed in the valley until about half 
its length had been traversed, after which its song was almost con- 
stantly heard until entering the forest. At the summit of Slide 
Mountain, however, several were noticed, and must have there been 
breeding These remarks apply, in strictness, to the seasons pre- 
vious to that of the last visit when, except on the mountain top, the 
bird was found to be uncommon, and in the valley but a single in- 
dividual was observed. 
It will be remembered that the first known nest of this species was 
discovered by Mr. Burroughs in this region. J 
Geothlypis trichas (L.) Caban. Maryland Yellow-throat. 
Not uncommon about the more settled parts of the valley, seeming 
to be replaced in wilder and more elevated land by G. Philadelphia. 
Myiodioctes Canadensis (L.) Aud. Canadian Flycatching Warbler. 
Though not abundant this species seemed to be generally dis- 
tributed in suitable localities. Mr. Burroughs gives an account of 
its nest.§ 
Setopliaga nitacilla (L.) Sw. American Redstart. 
Not uncommon about Pine Hill, but apparently rare in the Big 
Indian Valley, and not noticed at all on the mountains.
