Hummingbird Health Program

Dr. Holly Ernest and UW Ecology PhD student Braden Godwin launched the Hummingbird Health Program summer 2015 in Wyoming and Colorado.  Dr. Ernest started the Hummingbird Health Program in California in 2008 at University of California, Davis, and has now brought this examination of hummingbird diseases, population genetics, and ecology to the Rocky Mountain West.

Hummingbirds provide vital functions to natural areas, including pollination and insectivory. As ecosystem sentinels, they travel rapidly and widely from flower to flower and prey on thousands of tiny insects. Even more special is that they are stunningly beautiful birds, with bright iridescent colors. We need to learn their population numbers, biology, and health status in order to better conserve them. There are currently very few data on diseases, population health, genetic diversity and population structure for the hummingbird species breeding and migrating through Wyoming, Colorado, and the Rocky Mountain region, and the Hummingbird Health Program is helping to change that.

We developed genomic population genetic markers (SNPs, single nucleotide polymorphism loci) that can now differentiate the hummingbird species that breed and travel through Wyoming. Identification of “populations and species at risk” is vital for disease analyses. The genetics work helps identify what a functional “population” is within each of the species, and is vital to disease monitoring and assessment work.

Collaborators include Dr. Lisa Tell (UC Davis), Dr. Ravinder Sehgal (San Francisco State University), Andy Engilis (UC Davis), Dr. Bob Poppenga (UC Davis), the Hummingbird Monitoring Program, and others.

Conservation Genomics and Development of New DNA Tools

Using next-generation DNA sequencing and genomic research techniques, geographic information systems (GIS) to map locations, field identifications and health exams of individual birds, we are examining population biology and hummingbird health. So little is known about hummingbird ecology, diseases, and population numbers, this information is vital to determine which hummingbird species or populations are declining.

Braden Godwin (Brady) is focusing his PhD research on two species (Allen’s Hummingbird along Pacific coastal California, and Broad-tailed Hummingbird in the Rocky Mountain West).  Brady is using conservation genomic tools as well as field work and studies of environmental contaminants to determine population health and identify key problems important to hummingbird conservation.

Get involved with hummingbird field research

Do you have busy hummingbird feeders? We’re looking for sites to study hummingbirds in Wyoming and Colorado and would love to hear from you. Email us at hernest@uwyo.edu.

If you see any abnormal or sick hummingbirds, send in a picture and any information you have.

More opportunities coming soon, including hummingbird feeder watch.
