We did a quick Unit on Feathers for Lunch. We made notebook pages using the lapbooking resources on Homeschool Share, which included some poems and songs and a few simple activities.
For each of the common birds shown in the picture book, we looked at photos and listened to their sounds through the Cornell Lab of Ornithology Bird Guide. While we were doing this, we watched birds coming to our feeder outside the playroom window.
Two of the birds in our story were a house wren and a house sparrow. Two house wrens and a house sparrow were kind enough to visit our suet feeder at just the opportune time. The house wrens were eating like truckers. We looked at a couple of maps showing where the birds are found, and it appeared that we’re on their migration route. So we figured they were tired and hungry from their trip! We also read: 
The Robins in Your Backyard by Nancy Carol Willis (This is a lovely living nature book!
Beaks by Sneed B. Collard, illus. by Robin Brickman
(This is an excellent book which explores the functions of different kinds of beaks and touches lightly on natural selection and evolution. It was a little long and complex for Missy, but she easily grasped the central point, that the structure of a bird’s beak is related to what it eats and how).
Here is an activity we did, about a year ago, on bird beaks.
