laurel brakes, (. Kalmia latifolia ,) so that its loud, harsh notes are not 
heard until the first of May, when they fill the woods, greatly to the 
annoyance of the collector searching for rarer and more retiring 
species. Found in high woods, especially where there is an under- 
growth. Is not aquatic in any sense, but keeps on the ground rust- 
ling among the dry leaves for insects, and when disturbed flies to the 
nearest tree. 
66. Seiurus noveboracensis , (Gm.,) Nutt. — Water Wagtail. Quite 
common in spring and fall ; also breeds sparingly, having been found 
in July. Arrives in spring about May 1. Is eminently aquatic ; 
swampy thickets, thick gloomy woods interspersed with puddles, 
where it associates with Bhyacophilus solitarius , are favorite resorts. 
67. Seiurus ludovicianus , (Vieill.,) Bon. — Large-billed Water Wag- 
tail. This bird, generally considered so rare, we have found to be not 
at all uncommon at certain seasons in particular localities. From the 
20th of April to the 10th of May it may always be obtained, by an 
acute collector, in the dense laurel brakes which border the banks of 
and fill the ravines leading into Bock creek and Piney branch. We 
think we have seen it in June, which would' prove it to breed here, as 
is, indeed, very probable. We have not detected it in the fall. It is 
usually very shy, darting at once into the most impenetrable brakes; 
but we have sometimes seen it quite the reverse, and have shot a pair, 
one after the other, as they sat in full view before me unconcernedly 
wagging their tails. We have nearly always found it in pairs , even as 
early as April 20. Its note is a sparrow-like chirp, like that made 
by striking two pebbles together; but it has also a loud and most 
beautiful and melodious song, the singularity of which first drew our 
attention to it. 
68. Dendroica virens , (Gm.,) Bd. — Black-throated Green Wood- 
warbler. Spring and autumn visitant. None breed. In spring, from 
May 1 to 20 ; in fall, from September 7 to October 1. High open 
woods. Abundant. 
69. Dendroica canadensis , (Linn.,) Bd. — Black-throated Blue Wood- 
warbler. Like the preceding, but rather less numerous. 
70. Dendroica coronata, (Linn.,) Gray.— Yellow-rumped Wood- 
warbler. Winter resident. Exceedingly abundant. Arrive sec- 
ond week in October and remain until second week in May. Moult 
during the whole month of April, but before they leave are in full 
spring dress, though they have no song here. Most abundant in 
April and October, less so in depth of winter. Fond of hedges, 
orchards, copses, &c., but found everywhere. ( Albino obtained.) 
71. Dendroica blacJcburniae , (Gm.,) Bd. — Blackburnian Wood-war- 
bler. Spring and autumn visitant. None breed. In spring, from May 
1 to 20 ; in fall, from September 1 to 25. High open woods. Com- 
mon. 
72. Dendroica castanea, (Wils.,) Bd. — Bay-breasted Wood- warbler. 
Spring and autumn visitant. None breed. May 1 to 20; September 
1 to 30. More abundant in fall than in spring. High open woods ; 
sometimes laurel brakes, &c. 
73. Dendroica pinus , (Wils.,) Bd. — Pine-creeping Wood-warbler. 
Summer resident. Arrives early in March, and stays until October.,
