MORE PIGEONS! By Alex & Wendy, both age 9

On July 12 two pigeon nestlings hatched in the corner of the playground under a bench. They are from the rock dove family. Their scientific name is Columba livia. Today the nestlings are four days old. Their eyes are open and their down is starting to turn grey and they have started cooing. They cuddle together, looking cute.

Pigeon Eggs & Egg Care

The mother pigeon laid the eggs in a sloppy nest made of sticks and trash on the ground. Jose and Brandon found them while they were playing hide and seek.

Here’s what we learned about pigeon families: The father finds food at night while the mother sits on the eggs, then in the morning the father sits on the eggs while the mother looks for food. Pigeon eggs incubate for seventeen to nineteen days. After the eggs hatch, sometimes the parent sits on the nestlings and sometimes the babies are alone.

Crop Milk

Crop milk is food for baby pigeons. It comes from both the mother and father pigeon. There is a special chamber in pigeon throats. This is where the crop milk comes from.

Fledgling Period

During the fledgling period the nestlings stay in the nest. The fledgling period is thirty days. At the end of the thirty days, the nestlings leave the nest.

Here is a video of the nestlings. It's from the day they hatched.
