Nestlings Getting Big!
As we can see from this image when the nestlings first hatched they had very short down on the head and body, the down being rather sparse on the crown, nape and sides of the body behind the wings. The head and underparts were pale shades of buff with dark-brown patches on the ear-coverts (except directly below the eye). The brown marking on the head are patterned as in the adults. The juvenal feathering began to appear around 4 weeks old with the emergence of the primaries, followed by feathers of the head and upper parts. We will see the juvenal plumage fully developed over the next 2 weeks.
