Project abstract:
A species' ability to adapt to a changing environment relies on the diversity within its members. What is the basis of diversity across genetic, phenotypic, and behavioral levels? How is this diversity maintained in populations despite selection? We study the sexual phenotypes of hummingbirds as a pathway to researching these questions. The females of several hummingbird species have have multiple color "morphs". For example, in the white-necked jacobin hummingbird, females appear at first to look different from their male counterparts, yet closer examination reveals a surprise -- 20% of females are nearly identical to males in their feather coloration, and are nearly impossible to distinguish from males in the field. We use a variety of techniques, from behavioral observation, genomic sequencing, metabolic measurements, and hormone analysis to understand how and why evolution maintains multiple types of females. More recently we have also begun to investigate hummingbird vocalizations and their social contexts.
Individuals will have the opportunity to:
- Learn how to handle and observe hummingbirds in the wild,
- Develop and implement an independent project with a group of international scientists
- Develop strong skills in hypothesis-driven inquiry.
Skills:
Ability and willingness work with people from diverse backgrounds. Willingness to engage with and develop public outreach activities. Ability to work in hot, humid conditions on a daily basis. Experience working with and handling small animals preferred but not required.
