2019-09-23 Juvenile and Sub-Adult Birds

Western Bluebird - Sialia mexicanaIn the latitudes I frequent, July and August are the months I tend to meet most of my juvenile song birds. Waterfowl and raptors often produce young earlier, and when conditions permit, second broods of passerine birds can appear later, but the peak seems to be early summer. Guided by age old instincts, these creatures produce their young when food supplies are optimal.

I think I enjoy meeting juveniles in part, because of their looks and in part, their behaviour. I’ve found these younger birds are often more confiding than their hard working parents. And because the adults have been working hard to feed and care for this new generation, they are worn out and shabby compared to their pampered offspring. The feather patterns in birds of this age are often decorated with cryptic bars and color patterns. I imagine these must help them avoid the attention of predators, yet to my eye, they achieve a pleasing aesthetic quality not seen in their parents.

For my gallery presentation I’ve assembled images of birds that are past the downy chick phase, but who’ve not yet donned the garb of their parents.

If you are a keen and experienced observer, and care to provide your observations and descriptive information to any of these images, I welcome your contribution.
