Introduce your kids to bird watching by setting up a birdfeeder within easy view of a window. Children will have an easier time learning to use binoculars by starting with a fixed focus point. Children will focus on the birdfeeder (with the help of an adult if needed) and wait for the birds to come. They will see the birds like never before. Using a bird feeder will bring around many varieties of birds for their enjoyment.
Try buying different seeds to attract different varieties of birds. Provide a notebook where kids can record birds that they see. Show them how they can start their own life list. Buy a bird field guide or research sightings on-line.
