PLATE VI 

 DWIGHT PLUMAGE AND MOULT 



Passerina cyanea. Photomicrographs illustrating some of the 

 plumages. (Enlargement about 20 diameters.) 



Fig. i. First Winter Plumage, brown throat feather, newly grown. 



(J. Dwight, Jr., No. 2451, Sept. 23d.) 

 Fig. 2. First Winter Plumage, gray throat feather, worn. (U. 



S. Nat. Mus., No. 107845, March nth.) This figure 



does not do the actual feather justice.

still clasped by its sheath, and was growing beside the 



gray feather shown as Fig. 2.
