For Leah Crenshaw, M.S. ‘23 an active biologist and nature lover, finding harmony
between the natural and human worlds is her dream. Ecological preservation with no
human intervention isn't the only way to build a sustainable future. For example,
when she was studying the Texas frosted elfin butterfly during her undergrad to determine
if it should be put on the endangered species list, she realized that they had adapted
to transportation development and were, in fact, thriving.
“[I am interested in] ways to advance, simultaneously, biodiversity conservation and
human welfare around the world,” she said.
Crenshaw said what started out as a potentially sad story, that development on prairie
land into pasture had displaced the butterfly, actually ended up being positive because
the host plant, the native wild indigo, started growing in rights-of-way, railroad
tracks and other manmade areas, which then sustained the butterfly population.
She uses that lens in her research now to find common ground between natural conservation
and human development, including in her time at the University of Northern Colorado.
Recently, Crenshaw was awarded the prestigious National Science Foundation Graduate
Research Fellowship Program (NSFGRFP), which she will use at Cornell University as she pursues her doctorate. The GRFP recognizes and supports outstanding graduating
students who are pursuing research-based master’s and doctoral degrees in NSF-supported
science, technology, engineering and mathematics fields. According to the NSF website, thousands of former fellowship recipients have gone on to become leaders in their
field, including several Nobel Laureates and members of the National Academies.
“My dissertation has the potential to meet those goals of advancing both human and
socioeconomic interests and avian conservation,” Crenshaw said.
She came to UNC to pursue her master's degree in ecology, and, specifically, to study
ornithology under Professor Lauryn Benedict, Ph.D., a bird behavioral and animal communication specialist.
Benedict, a biology professor in the College of Natural and Health Sciences (NHS)
is part of a global team working to document and describe the songs of female birds.
In North America, many observers assume that every singing bird is a male, but recent
research suggests that females sing too. With the help of citizen scientists, Benedict
and her colleagues are working to collect samples of female bird songs from around
the world. In her own backyard, she and UNC students are tackling this question by
examining when and why canyon wren females sing.
Crenshaw came to learn from Benedict, as she is particularly interested in studying
female birds, which have been understudied, historically, she said.
At UNC, she studied the western meadowlark, a yellow prairie bird that sounds likeR2-D2 and can be found along the Poudre River Trail. Crenshaw also led a team of undergraduate
student researchers through the summer, for which she won a mentorship award.

“As a mentor, she is thoughtful and detail oriented. She trained students through
all phases of the research process, from initial literature exploration to a polished
final presentation,” Benedict said. “Additionally, Leah’s research activity led to
teaching improvements in courses at UNC, as she incorporated her expertise into our
Crenshaw credits UNC for placing a much stronger emphasis on teaching for graduate
students than most other universities. During her time here she took advantage of
learning opportunities, including a Center for Enhancement of Teaching & Learning
(CETL) workshop and NHS DEI day.
Along with the mentorship award, she received a Dean’s Citation, Academic Scholar
Award, Graduate Student Excellence in Mentorship Award and a School of Biological
Sciences Graduate Assistantship.
Benedict said that in the world of ornithology, Cornell is the place to be.
“Cornell is the epicenter for bird research in the United States, so she’ll be in
a very prestigious program,” Benedict said.
