Baby pigeons are seen fairly often, just not newborns.
This is because pigeons make excellent parents. To start with, they hide their nests well in crags and crannies.
When the nests are well hidden and sturdy, they lay two eggs, then spoil their babies rotten when they hatch, until they leave the nest.
As a consequence, baby pigeons quickly become plump and large, about the same size as their parents when they go off into the world alone.
You’ve heard of the delicacy squab, I trust? That’s a plump baby pigeon cooked just so.
If you want to spot the young in a flock, here are some hints: Look for them in the summer and spring months.
If you’re feeding a flock, watch the ones that don’t aggressively go after your bread crumbs; you may find your babies there.
Beyond that, there may be fluffy down sticking through their regular feathers; they may show a little bit of lip around their beaks from being recently fed by their parents; and their heads may not be as broad.
