The male in juvenal plumage is somewhat Uke the adult female, 

 but lacks the orange crown patch; is of a duller, less yellowish olive- 

 green above; and is much duller, more grayish, less yellowish below. 



The female in juvenal plumage is much duller, more grayish above

There are indications of molt among the contour feathers of both 

 these young birds.
