“Bird-Airplane” Collisions and Forensic Ornithology

The New York Times recently published an article, Trafficking in Contraband that Sings, on birds from Guyana that were being smuggled into the US for singing competitions. Strangely enough, these competitions are judged by humans and not by female birds. The part of the article that intrigued me the most, however, also aired on NPR, about the Forensic Ornithologist (Dr. Train) called upon to testify in court regarding these birds. This was a field of science new to me and, curiosity piqued, I did a little research.

Forensic Ornithology has been used in a variety of ways and with a variety of methods including DNA or by “eyeballing” the species. Experts in the field have been called upon to help solve such problems as bird-airplane collisions, homicide investigations, and endangered species’ poaching cases. It is an interesting field of study where you have to incorporate a lot of information on feather structure, bird bones and even DNA.

Take bird-airplane collisions like the Hudson River Landing. By knowing which bird(s) collided with the airplane, a management plan for that bird species can be made to prevent such collisions in the future. (As an aside, is it really fair to put the bird first in “bird-airplane collision”? Or what about “Bird hits External Tank during Shuttle Launch”? As if the bird was the one traveling with boosters strapped to its keel.)

All kidding aside, analysis of the bird remains can help focus on which species may need management. Leading to alternate aircraft routes during peak bird activity to avoid potential collisions, using bird radar to track flocks of birds such as NASA uses and even sound cannons strategically placed to keep birds out of the aircraft’s flight path.

So where does one go to have birds or their remains identified? If it is a larger sample, the Museum’s very own collection can help. Dr. Dan Brooks, Curator of Vertebrate Zoology, has identified parts of birds for museums and the USF&WS (U.S. Fish & Wildlife Service) to ascertain whether or not it was a species listed as Threatened, Endangered or CITES. He has also used the collection (and his own vast knowledge) to identify feathers in Indigenous people’s ornaments, including the “Ice Queen” mummy of National Geographic fame. Pretty cool! For the high-tech study of bits and pieces used as evidence in court cases, professionals usually turn to the NMNH’s Feather Identification Lab.

In another article by the NY Times, the initial forensic analysis performed by the Lab of the remains collected from a collision produced deer DNA. That seemed odd, since the collision took place at 1500 feet. Analysis of a feather sample that was also collected identified the bird as a Black Vulture, evidently with deer remains in it’s stomach. Science is awesome!

NASA Fly-By at the George Observatory

At the end of November, the Space Shuttle Endeavor made its way back to Earth – and was rerouted to a base in California due to poor weather at Kennedy Space Center. To get the shuttle back to Florida and ready for its next trip to space, it was piggybacked on a modified 747 and flown cross-country on Dec. 11. When it passed over Houston, a science class taking place at the Museum’s George Observatory had a front row seat as it flew overhead. Here’s what Astronomer Barbara Wilson had to say about the experience:

George Observatory/HMNS staff received this communication from NASA pilot Triple Nickel.

“For those who care the Shuttle landed in Ft Worth, if the weather is good Thursday the 747 will fly from Ft Worth down to JSC for a flyby and then back to Barksdale AFB.”

Then we received another notice from Flight Director Chuck Shaw of the actual flight path and times.  We watched the flight path on the Internet and figured out when the 747 with shuttle piggybacked on top would pass over the George Observatory,  all of the students and their Moms went up with us to the main observatory deck and we heard the plane first then saw it pass directly over the George Observatory at very low altitude.

Our home school students were here today taking a class on Origins of Flight and a Challenger Mission. 20 students were thrilled to get to see the Shuttle piggybacked on the 747!

The pictures are of the Space Shuttle being transported to NASA at 11:55 am today 12/11/08 and were taken by Laurie Knight, mother of two students attending classes. Thanks Laurie.

You can see more of Laurie’s photos (plus lots of other fabulous visitor-submitted photos of the Museum and its satellites) at the Houston Museum of Natural Science pool on Flickr or on Barbara’s Flickr photostream. You can also see another amazing closeup shot of how the 747 and the shuttle were piggybacked, taken by AlphaTangoBravo when the 747 came closer to the ground, here.
