Yes. There is no reason to doubt that the nestlings you heard were the =
offspring of this 1st year male(I prefer this term rather than immature) =
.
It takes two years for male Orchard Orioles to attain the adult plumage. =
 They are perfectly capable of breeding(you saw evidence of this), but =
generally less likely of obtaining a mate than the 2 year and older =
males because they usually have less desirable territories. Of course =
this depends on the number of orioles present.  Two other local species =
in the same sort of situation are American Redstarts and Red-winged =
Blackbirds where 1st year males have different plumages than the older =
males.
