 tips forming two bands across the wing. Bill pale yellowish. Feet

 the feathers yellowish-olive, this color often almost concealing the 

 darker central color. Wings as in older specimens. Below pale 

 yellowish-olive or buff, obscurely streaked on the breast and sides 

 with brown. A yellow superciliary stripe.
