On the day she stayed home, we were planning a "bird beaks" lesson based on the recommended activity in the KONOS curriculum. It involved finding household items that resemble various different kinds of beaks, and foods (or non-foods) that resemble tasty bird treats - and then experimenting to figure out which kind of beak (and bird) works best with which food item.
We made spaghetti to simulate worms and used peanut butter to stand in for mud... found some unpopped popcorn for seed... tossed some uncooked rice on a plate to be bugs... and so forth. The kids had a great time with tongs, tweezers, and other "beaks," trying to grab each type of food. As they decided which type of food went with which type of beak, we then looked through our bird guides to find real-life examples of the birds, beaks, and food.
Tweezer-shaped beaks work well to pick up seeds like popcorn.
The EyeWitness Birds Book is a great image resource
