Bird Feet!

Continuing our unit on birds, today's class focused on feet adaptations. While out on our hike, we were excited to spot a couple Bluebirds bouncing around and even more excited to find a couple owl pellets on the trail! 
Look at their beautiful snow village! 
 After reading a book called "Ducks Don't Get Wet" by Augustus Goldin, we did our own experiment to see if the book was correct. Everyone picked a different bird feather and dipped it into a glass of water. To the class's surprise the feather was dry when we pulled it back out! We learned that this happens because birds cover their feather in oil. And because oil and water don't mix the oil acts as a barrier for the feather keeping it dry even when a bird is underwater! 
We examined different bird feet and discussed the function of each of the feet. The feet of the Ring-necked Pheasant is perfect for scraping and searching the ground for bugs. 
 The feet of the Common Merganser is perfect for diving and swimming in the water.
 The Great Horned Owl feet are perfect for catching and holding on to its prey.
Next week we will learn about what makes bird bones so special and we will create our own unique bird!
