 piper and Killdeer. 



The Marsh .Issociatioa : Marshes are so poorly developed 

 in this region that no adequate description is possihle. The 

 one at the month of Bessey Creek is little more than an acre 

 in extent. In it occurred a small colony of Great lUue Herons 

 and one or more Marsh Hawks were not infrecpiently in the 

 vicinity. .After the migration had commenced bitterns were 

 occasionally seen. At Smith's Bog, two miles east of the sta- 

 tion, are several acres of typical marsh and here the \'irginia 

 Rail, Cooper's Hawk, Killdeer,^ vSolitary Sandpiper and tracks 

 of the Great Blue Heron were observed. 



The Loii'hi)id Thicket Association : Distinctly hydrophytic 

 thickets, such as the Salix-Cephalanthus association and the 

 Alnus-Betula association, are represented by very narrow strips 

 along the streams and lakes, and it is hard to detect a typical 

 avian fauna. The Ijirds most commonly seen in the thickets 

 are the Song Sparrow, Swamj) Sparrow, Indigo I'.unting. 

 Warbling A'ireo, Maryland Yellowthroat, Catbird, Winter 

 Wren, lilack -capped Chickadee and Whip-poor-will. 



The Cedar Boi^ Association : A considerable portion of the 

 region is occupied by this type of vegetation, which occurs in 

 low wet areas where there is usually little drainage. The cedar 

 {Thuja occidentalis), balsam (Abies balsamea), tamarack 

 {Larix hiricina) and the spruce {Picea mariana) form a nearly 

 impenetral)le jungle. 



Birds are really quite plentiful, though on account of their 

 shyness and the ease with which they can hide in the dense 

 coniferous growths, a different impression is usually received. 

 Species of this group are nuich more likely to be discovered 

 l)y note alone than birds of tlie other vegetational types. The}- 

 are Ruffed Grouse, Broad-winged Hawk, Hairy Woodpecker,
