Interested in assisting in these or other research projects?
I am interested in a variety of topics related to birds -
phylogenetics, population genetics, morphology, behavior, and sexual
selection among them. My current research focuses on island
adaptations and the ability/willingness to fly over large water bodies.
I am working towards a masters thesis in the Department of
Zoology, University of Florida, advised by Dr. Dave Steadman, studying the birds of Trinidad and
Tobago. These two islands are land-bridge islands (as opposed to
oceanic islands) - they were connected to the South American continent
11,000 and 14,000 years ago, respectively, and thus the species present
are likely remnant populations rather than populations of colonists.
This provides a unique opportunity to tease apart island
adaptations from traits important in the ability to colonize an island.
I have also integrated a genetic component to this project - I am
interested in knowing which of my study species have diverged
genetically as well as morphologically between the islands. This
has direct conservation implications, because species whose populations
have diverged genetically are not likely to be dispersing between the
islands. Thus, the extirpation of one of these species from
Tobago, for example, would not only represent a loss of a
morphologically and genetically distinct group, but the species would
not be re-established on Tobago from neighboring populations.
Stay tuned for results, which I hope will be coming soon.
I am conducting my molecular work in the lab of one of my very generous
committee members, Dr. Rebecca Kimball.
An outstanding zoology
undergraduate, Erica Egan, helped me with the genetic
work as part of her senior thesis. She presented her senior
thesis at the Zoology Undergraduate Research Symposium this April and
graduated from the University of Florida with high honors. I am
very proud of her accomplishments!
Other research projects I am currently working on include analyzing
data from the Florida Museum of Natural History bird collection.
We have found trends in the sizes of flight muscles in columbids
(pigeons and doves) on Pacific islands. The percentage of total
body mass contributed by flight muscles in a variety of columbids is
smaller on smaller, more remote islands than on larger islands close to
continents. We are currently increasing our samples of other
groups of birds in other areas of the world to examine whether these
trends are universal or limited to columbids in the Pacific.
I am also currently identifying bird bones from an archaeological site
in Guatemala. By integrating paleontology, archaeology, and
modern surveys, we can develop an understanding of how humans have
affected avian communities over time.
Some of the species I am studying on Trinidad and Tobago include:
Copper-rumped Hummingbird, Amazilia tobaci Barred Antshrike, Thamnophilus doliatus


Bananaquit, Coereba
flaveola
Bare-eyed Thrush, Turdus nudigenis


Rufous-breasted Hermit, Glaucis hirsuta
