THE BIRDS OF WISCONSIN. 
Hoy. A single wing of a decomposed specimen was preserved 
by Thure Kumlien. This was found on the shores of Lake 
Koshkonong in the early fifties. Both of these were young 
birds in the white plumage, and no doubt straggled north- 
ward with other young herons. These, we believe, are the 
only authentic records for the species in Wisconsin, and can 
only be considered as purely accidental. 
Ardea virescens D&nn. GREEN HERON. 
Common summer resident. Does not nest in colonies, but 
usually in scattered pairs, sometimes two or three together 'n 
a favorable place along some wooded stream or pond. Found 
as far north as the shores of Lake Superior at least. Some- 
what diminished in numbers of late. 
Nycticorax nyctieorax naivius (Bodd.). BLACK-CROWNED 
NIGHT HERON. 
Common summer resident. Always somewhat erratic in 
distribution, sometimes frequenting only the thickest and most 
retired woods and swamps, and to a considerable extent 
nocturnal, or rather crepuscular in habits, it is easy to get a 
wrong impression of its numbers, and many people never 
suspect its presence. There is also no doubt that the night 
heron is much more numerous in Wisconsin than formerly. 
Large colonies, or breeding rookeries, have been located to 
our knowledge at Lake Koshkonong, Albion, Stoughton, Fox 
Lake and Delavan, as well as in many other localities. Seems 
to nest indifferently in trees or on the ground in marshes. 
The marsh nests that we have examined have always been 
placed among the cane (Phragmites phragmites), and not the 
wild rice, as stated by Nelson and others. 
ORDER PALUDICOL^E: CRANES, RAILS, 
ETC. 
FAiilLY GRUID^E: CRANES. 
Graft americana (Linn.). WHOOPING CRANE. 
Formerly of regular occurrence in the southern and western 
part of the state during migrations, unquestionably breed- 
ing to some extent. Thirty or forty years ago it was not 
rare to see a few among the enormous flocks of sandhill cranes
