SQUIRT GUN SCIENCE! By the Kids in Room 2
We are third, fourth and fifth graders from a public school in San Francisco's Tenderloin Neighborhood. This blog is a project of Robyn Carter's classroom (Room 2). It's a place to share our art and writing with other kids and teachers.
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.
Last fall we planted purple kale, rainbow chard and lettuce in Room 2’s garden. Yesterday we finally harvested all of our winter greens. Look at all the colors. The chard has green leaves, and red or yellow stalks and veins. Yesterday, we ate lettuce with sesame dressing. Today, we will steam the chard and kale with rice for lunch. We will eat light brown rice because it has nutrition in it. We will eat it with soy sauce or sesame dressing. Next week we will plant beans. We can’t grow tomatoes because Tenderloin summers are too foggy.
