OWL PELLETS-products of a
special gizzard • Several hours after an owl eats,
the fur, bones, teeth & feathers of its prey, still in the gizzard, are compressed into a pellet the same shape as the gizzard.
• Once formed, the pellet moves up from the gizzard and is regurgitated.
![Page 54: 6th Grade Ch. 4 Sec. 1 Birds](https://reader034.vdocument.in/reader034/viewer/2022051513/547a6549b4af9f67478b4574/html5/thumbnails/54.jpg)
OWL PELLETS-products of a
special gizzard
• Owls can't eat while a fully formed pellet is present, blocking the digestive tract.
• When an owl is ready to produce a pellet it usually closes its eyes, gets a funny look in its face, doesn't want to fly, and when the pellet is ready to come out, the beak is opened and the pellet simply drops out.

Egg activityEgg activity
• Activity: Air Holes in Eggs
Eggs are covered with tiny holes, too small to see with the naked eye, that allow oxygen to pass into the growing baby and carbon dioxide to pass out.
To see these breathing holes in action, make a small hole in one end of a chicken egg.
Use a needle to break up the yolk, and shake all the yolk and white out of the egg.
Seal the hole completely with tape. Now, place the egg in a bowl of water and hold it under. You will be able to see air bubbles rise right out of the
egg’s shell as the air trapped inside seeps out through the tiny holes!
