Dear National Science Foundation,

I would like to express my sincere gratitude to the NSF for funding my participation within the 2001 Research Training Program at the National Museum of Natural History. In my ten-week stay, I have seen and been a part of the outstanding research that occurs at the Museum of Natural History.

My research entails the microscopic feather character analysis of cranes, rails, and allies from the order Gruiformes. Microscopic feather character analysis is a new tool that ornithologists have used to show that certain feather characters (i.e. node shape, barbule length, node width and pigment) can be traced back to particular groups of birds, especially in identifying groups involved in bird aircraft collisions ("bird strikes"). The concepts and techniques of this new tool are based upon the work of Roxie Laybourne and Dr. Carla Dove at the Smithsonian Institution, National Museum of Natural History. In this study feather characters were coupled with and compared to DNA to determine whether feather characters that are used in feather identification can be applied to phylogeny and evolution of birds. Our results suggest that feather characters can be used to determine phylogeny and should be combined with other characters. I am very pleased to inform you that my participation in this program has enthused me to continue my research at New Mexico State University, under the direction of Dr. Peter Houde.

I am very grateful to the foundation, for your generosity, and for a once in a lifetime opportunity to work with the nation's top scientists. I have learned so much during these past 10 weeks, I am very thankful that NSF believed in me to fund my participation in this program. Once again thank you very much for your generosity.


With Regards,
