A Tale of Tongues

The five Northern Flicker chicks are growing fast! Now fully feathered, they look like entirely different creatures than the long-necked, blind, pink things that hatched out just a few short weeks ago.

Not only have their eyes opened and their feathers grown in, but their claws have developed and the chicks are getting big. That means they have to climb to the top of the box to get fed at the entry hole, which leads to furious fights involving wing flapping and head pecks to either hold onto or usurp the prized position. In between meals, they spend a lot of time wiggling their tongues around and licking the box and each other. I assume this is a way of exploring their surroundings, like a toddler shoving everything into his/her mouth in order to taste it.

The Northern Flicker has the longest tongue of all North American birds at 4 or 5 inches long. This tongue wraps around inside its skull and can dart out 2 inches past the end of its bill. Flexible and sticky with a lightly barbed end, it’s the perfect implement for wriggling into tight crevices and lapping up ants, the flicker’s favorite food. Any ants that escape feedings are now quickly slurped up by these ever-hungry and watchful little chicks.

While I’ll be sad to see these little guys leave the nest, I’ll also be excited to watch them take their first flights. In fact, they could be fledging any day now. Northern Flickers generally fledge (develop wing muscles and feathers of sufficient strength to allow flight away from the nest) between 25 and 28 days after hatching so the 3 older chicks could fledge as early as this weekend. Stay tuned!
