Bald-Headed Clay-colored Thrush Shows Budding Pin Feathers
Blue Jays and Northern Cardinals aren't the only bald-headed birds that you'll see on the Bird Cams in late summer. This all-at-once molting (i.e. feather replacement) strategy also happens to birds in other parts of the world. Take this Clay-colored Thrush on the Panama Fruit Feeder cam for example. Can you see the small, white spikes protruding all over its head? These are pin feathers. Pin feathers are developing feathers that are encased by a waxy sheath, which protects the budding feather as it grows before it dries and falls away.
