Analysis
Birds have a variety of different feet shapes and structures. Read
about the different bird groups below. Then, look at the pictures of
bird feet and match the bird group to the type of feet. Explain your
reasoning for each decision.
Raptors
Raptors, also called birds of prey, include hawks, eagles and
owls. Birds of prey hunt and eat other animals. These birds
capture, kill and carry prey with their feet.
Water birds
There are many different types of water birds, such as ducks,
flamingos and seagulls. These birds spend a large part of their
time in or around the water. Water birds have feet that help them
to swim and to not sink while walking on top of soft sand near the
water’s edge.
Woodpeckers
Woodpeckers are birds that use their strong beaks to drill holes
into plants and extract insects inside the plant. They have feet
that help them to climb up, down and sideways along tree trunks.
