The very great variation in size of this species has not usually been recognized. I / 

 have measured individuals from 23 to 34 inches iu length, with an extent of wing from,' *'*■ 

 32 to 43 inches; the wing 9^ to 13, and other measurements to correspond. The colora- ^^.j^.'^ 

 tion varies interminably; even the characteristic velvety black spot on the side of the' J 



neck is sometimes obsolete. 



Audubon has giveu accounts of nearly all our Herons, with which he 

 Tras very familiar, in a series of admirable biographies, leaving little to 

 be desired. He was less fortunate in the case- of the Bittern, admitting 

 that he never had a good opportunity of observing all its habits. This 

 being the case with " the American Woodsman,"' it is less singular that 

 no other writer has completed the history of the species. Latterly, 

 however, ilr. Endicott has gone far toward supplying the deficiency, in 

 his excellent article above cited ; and Mr. Samuels gives some interest- 

 ing j)articulars. Every one knows the Bittern by sight, and has a gen- 

 eral, if vague, idea of its character, but few have become familiar with 

 its ways. Wilson conveys but little information, and that not entirely 

 to the point. Eichardson fixes its northern limit at 58°, but has httle 

 more to say. Kuttall's account is chiefly a compilation from these two 

 sources. Although I am tolerably familiar with the bird, I have never 

 seen its nest, or found it where 1 could suppose it was breeding. 

 According to the best accounts, its i^ecnliarities in respect of nidifica- 

 tion are, that it does not assemble in communities, at any rate of large 

 extent, to breed, and that the nest is usually placed on the ground. 

 Mr. Samuels says : "It breeds in communities, sometimes as many as a 

 dozen pairs nesting within the area of a few rods. The nests are placed 

 on low bushes, or thick tufts of grass, sometimes in low, thickly-wooded 

 trees ; and are composed of coarse grasses, twigs, and a few leaves. I
