Some birds hunt other animals to get their food, while some have to be
on guard against animals that want to hunt them. Can you tell the difference
between a hunter and a hunted bird?
HOW'S THE WATER?
Birds need safe drinking water as well as food. See what can happen to
birds if their water supply is polluted, then learn how to do some experiments
and test the safety of your water.
Good food can be hard to get at. Birds have evolved beaks that are
very good at gathering their special food. Can you figure out what
a bird eats by looking at it's beak?
Attract certain kinds of birds by putting out specific foods. We show
Test and determine the food preferences of backyard birds.

OBSERVE: spend time outside identifying birds that live near your
QUESTION: Predict which birds will eat certain types of food from
your feeder. Can you think of anything that would make different
birds choose different foods?
BEGIN YOUR EXPERIMENT: this will be a scientific study of backyard
MAKE A HYPOTHESIS: Complete this sentence
"The ________ will eat the ________ because ______________."
TEST YOUR HYPOTHESIS: Place 4 to 6 different types of food in the
tester trays. Arrange the trays next to each other.
GATHER INFORMATION:Watch the birds eat from your feeders for one
week. Record the number of birds that take each kind of food. Your
chart might look like this:
ANALYZE YOUR INFORMATION: Chart the
different birds that came to each food.
EXPLAIN YOUR RESULTS: Compare your hypothesis to what you actually
saw. Are the birds that go to a certain food similar in some way
(like size, or beak shape?). If there's time, you could change your
hypothesis, change the foods offered, and gather new data.
The different birds you see in your backyard or park eat lots of different
things. In this experiment, you'll offer a variety of foods. Keep track
of which birds prefer which foods, and come up with some theories about
