tirely missing, in the parts of the mountains covered by these notes ; conse- 
quently the only time I met with this bird was during a migratory “wave”, 
September 29, 1914, when two individuals in company with a dozen or more 
birds of several species alighted to feed among the trees of the grove through 
which I was passing. They were quickly distinguished by the characteristic 
notes, often uttered; whereas other species present were quite silent. 
Dendroica discolor. Prairie Warbler. A common summer visitant, found 
to the summit of the range, if abandoned clearings, old orchards, and lumbered 
over areas were present. Arrived about April 28 ; sang constantly up to May 
25 ; departed very early ; none seen after July. 
Seiurus aurocapillus. Ovenbird. Excepting for such areas as had been 
recently cut over, Ovenbirds were everywhere present as summer visitants 
wherever the forest remained. Reached the region by the middle of April, 
and did not depart until September 15. 
Seiurus noveboracensis notabilis. Grinned Water-Thrush. The other 
members of the genus had left when this species arrived. It was recorded 
September 18 and 21, 1914, a single bird being seen on each date. 
Seiurus motacilla. Louisiana Water-Thrush. Common summer visitant; 
confined to the vicinity of the larger streamlets. While its alarm note was 
nearly always sounded before I could locate the bird, yet, after the nesting 
period had passed, it was much more easy to approach than before. Young, 
able to fly, were found June 4; later broods appeared up to the end of July. 
A few birds showed evidence of partial molt, even in April ; by the 10th of 
July, practically all adults were in ragged plumage; but by the time of de- 
parture (after August 15), the new plumage was fully acquired. 
Oporornis formosus. Kentucky Warbler. A favorite location for this at- 
tractive species was a shaded slope where numerous springs issued forth ; 
it was also frequently found in low situations along streams. The earliest 
arrival was recorded April 22. Young were about June 6. Departs early; but 
a few birds lingered until September 7. One of the most confiding of small 
birds. 
Oporornis Philadelphia. Mourning Warbler. It is pretty certain that 
this is one of many species of migratory birds preferring to pass around, 
rather than over, the range. With habits and movements resembling the 
Hooded Warbler, it was difficult to distinguish between the tivo species in 
the dense underbrush shaded by forest trees. So, of the limited number ven- 
turing into the region, few were seen. But records are at hand showing its 
presence from the end of April, to as late as May 21. 
Geothlypis trichas trichas. Maryland Yellowthroat. Howell writes of 
this as one of the commonest of small birds within the state ; yet 1 rarely met 
with it in the higher parts of the range. Several were seen during late April, 
1913; and one was secured from a brush pile in a pasture May 21. 1914. 
Icteria virens virens. Yellow-breasted Chat. A well distributed summer 
visitant; found on the highest hills, if bramble patches existed. One of the 
later arrivals, none being noted before April 30; but the bulk of its number 
reached the mountains together. Young, fully feathered, seen July 18. Chats 
left for the south before September. 
Wilsonia citrina. Hooded Warbler. Chooses rather drier woodlands 
than the Kentucky Warbler, but equally numerous, also arriving earlier and 
departing later. Extreme dates were April 18 and September 24. Males
