Family CLXX. AMPELIDuE. (The Chatterers.) 



Primaries 10, or apparently 9, the first in our species rudimen- 

 tary and displaced; biU stout, triangular, depressed, decidedly 

 notched and hooked, with the gape very wide. Tarsus short, with 

 the lateral plates more or less subdivided, their covering often un- 

 like that of the other Oscines ; lateral toes nearly equal. As now 

 recognized, a small family of 6 or 8 species, constituting two groups 

 which bear little resemblance to each other. 



The Ampelince includes the three species of Ampelis. They are 

 crested birds with a soft plumage of a handsome cinnamon drab 

 color ; the ends of the secondaries, and sometimes of the tail feathers 

 also, are tipped with horny appendages, looking like red seahng- 

 wax ; these often absent in $ . The tail is tipped with yellow or 

 red. The Wax Wings are migratory and gregarious, feeding on 

 insects and soft fruits. Their voices are weak and wheezy, and 

 they can scarcely be considered as songsters. 



a. Wings pointed ; tail short, truncate ; primaries apparently 9 ; the first very- 

 minute ; no rictal bristles ; nostrils concealed by bristles. (Ampelince. )
