As a plane takes off from Reagan National Airport, one of its wings strikes a bird in midair. Thousands of such bird strikes happen every year, killing the birds and causing millions of dollars in damage to aircraft. What can be done?

The first step in the process is to accurately identify the type of bird that was struck. After a bird strike occurs, airports are encouraged to send the remnants, called “snarge,” to the Feather Identification Lab here at the Smithsonian National Museum of Natural History. The lab, headed by Dr. Carla Dove, identifies the bird that was involved and reports the information back to airlines and airports. Airport managers and airlines use the feedback to design airplanes that are less susceptible to damage by birds and to modify airfield practices and airplane designs to reduce the chance of bird strikes.

Students Investigate a CaseStudents study feathers.
During the "Bird Strike Whodunit" school program, students replicate the Feather Identification Lab’s processes for one of Dr. Dove’s actual cases. In order to do so, students look at three types of evidence: the whole feather, DNA, and feather microscopy. To identify the whole feather, students compare their samples to our bird collections in   Q?rius. They also use scientific tools such as calipers and reference guides to learn what part of a bird the feather came from, and what different parts of a feather can tell us about the bird species.

At the DNA station, students learn the basic building blocks of DNA and how to identify specimens using this type of evidence. Once they identify the species from the snarge samples, they may be surprised!

Finally, at the feather microscopy station students examine feather barbs under a compound microscope. Bird species have unique nodes on their feathers, so students can identify the species by sketching what they see in the microscopes and comparing the sketches to a reference guide.

Every airport has different strategies for dealing with bird strikes, so multiple solutions need to be examined and thought through!
