YOUNG TRUMPETERS 251 



A broad line down the center of the crown, splitting 

 apart on the hind crown and nape, and coalescing again on 

 the hind neck, was pale cinnamon. A complex series of cres- 

 cents on the upper and mid-back, two latero-dorsal lines ex- 

 tending quite to the tail, and an elaborate pattern on the 

 sides of the body and the outer thighs were cinnamon, the 

 thigh markings paler, more buffy. 



The background of the lower neck and upper back was 

 black. The background of all the remainder of the plumage 

 two lateral crown lines as far back as the lower neck, the 

 mid and lower back, rump, sides and outer thighs all were 

 cold, grizzled grey, varying from cinereous to plumbeous. 



The wing feathers, which were sprouting strongly, were 

 almost concealed by the long, fluffy cinnamon down. This 

 down was very evenly distributed on the sprouting barbs, 

 each stem of down usually resting firmly on an individual 

 barb. Ten primaries were sprouting, slightly longer than 

 the secondaries. All ten were black. The 6th was the long- 

 est, measuring 61.5 mm. Sixteen secondary flights had 

 sprouted, the outer five unusually strong and black in color. 

 The 6th was slightly tinged with grey, while the succeeding 

 ten were wholly grey and diminished rapidly in size, from 

 43.5 to 11 mm. 



The iris was hazel brown. The bill black with restricted 

 areas of ivory white along the culmen, lower edge of upper 

 and tip of lower mandible. Inside of mouth, pale flesh, ex- 

 cept for posterior palate which was black. Legs and feet 

 chaetura drab, paler on larger scales, darker on soles. 



When the chick was two months old the down still per- 

 sisted on the head, neck and posterior dorsal areas. 



As typical of an adult in full molt, I present the details 

 of wings and tail of a bird shot on July 20. 



The three outer primaries were old. 



4th nearly full-grown. 



5th a quarter grown sheath. 



All the remaining primaries new.
