Science Projects on Bird Beaks
Science projects on bird beaks enable students to explore how an animal's physical characteristics have adapted to different habitats. You can research, observe and test a large variety of beak types, ranging from a hummingbird's stinger-like beak to a heron's spear. Depending on the food source, explain why one beak would be more efficient than another and help a bird survive.

Observe Beak Types
-
Gather binoculars and a bird field guide. Locate places where you can watch birds, such as a park, forest, pond, lake, beach, zoo or pet store. Ask an adult to come with you to your chosen place and take the field guide or pictures of birds. Input at least 10 different species you observe in a table. Record your predictions on the kind of lifestyle a particular species has based on its beak in a table. Write down how the bird might forage and how it might spend its time. Does the bird claw through dirt for insects or does it swoop down and grab fish with talons? Does the bird swim or does it prefer treetops? Do research on each observed species. Record your findings on the bird's lifestyle next to your predictions based on observation. Create a pie chart that reveals the percentage of correctly predicted cases regarding how the bird spends its time and another chart for how the bird eats. Draw conclusions as to the accuracy with which you can ascertain a bird's lifestyle based on its beak.
Determine Beak Efficiency
-
Research various types of beaks, such as the shredder, cracker, probe, speak, tweezers, probe, chisel, strainer and Swiss Army knife. Note the differences in their shapes and functions. For example, cardinals and sparrows have cracker beaks to break open seeds. Woodpeckers have chisel beaks to burrow into insect-infested wood. Herons have long pointed bills to spear fish. Create a large poster that matches the type of beak with the bird's food source. Explain how a beak's features and shape enable the bird to access its food source. Select one bird species and pose three different threats to habitat that would diminish that bird's food sources, such as climate change, an invasive species, a virus that wipes out insects or animals or deforestation due to fire or people's need for farmland. Describe how the bird's beak would need to change and adapt to the threat to ensure survival.

Test Different Beaks
-
Gather clothespins, forceps or tweezers, craft sticks and a rounded spoon. Glue one craft stick to each side of the tweezers or forceps to simulate a long, pointed beak. Use the clothespin as a curved beak and the rounded spoon as a scooping beak. Gather gummy worms or rubbery candies, raisins and nuts at the grocery store. Use the raisins as bugs, and the nuts as small animals or shellfish. Create a table that lists three beaks for each food source. Test how many of each food source can be picked up with each type of beak. Record your results in the four tables. Determine which beak is most efficient at picking up each food source and describe the features and advantages of that beak's design.
Design a Beak
-
Gather five different types of products that can simulate the food sources for birds, such as sunflower seeds, gummy worms, foam squares, popcorn, rice, and a graduated cylinder filled with water. Experiment with beaks made from different objects, such as an eyedropper, tweezers, clothespins, chopsticks, slotted spoon and a skewer, to access different foods. Match the beak to the food source, and then design a beak that incorporates the optimal features to access a particular food source. Illustrate a beak for each food, and then describe how it would function and how its structure has adapted to allow your bird to survive.
