WHP Advisory Committee Grows
As the WHP says farewell and many thanks to long-term Advisory Committee member Barb Bresson, we also welcome several new participants. Jamie Ratliff, Kelli van Norman, Chelsea Waddell, and Deanna Williams bring their expertise to our committee with their backgrounds in research, monitoring, restoration, and conservation. We appreciate their joining our team!
Hummingbirds Reveal Evidence of Insecticide Exposure
Lisa Tell is an avian veterinarian at the UC Davis School of Veterinary Medicine and Director of the Hummingbird Health and Conservation Program.

With support from WHP, University of California at Davis researcher Lisa Tell and her colleagues developed a method to detect the presence of pesticides in hummingbirds. They then used their technique to test for as many 150 drugs, pesticides, and other products in Black-chinned and Anna's Hummingbirds in California.

The results of their work demonstrate that over 68% of their specimens were exposed to insecticides and that the chemicals were found mostly on feathers, rather than in internal organs. This result raises the question about whether or not hummingbirds ingest insecticides or are exposed to them in other ways. The use of synthetic chemicals has increased rapidly, despite Rachel Carson's cautionary words in Silent Spring. Dr. Tell hopes that her work will contribute to our understanding of how chemicals impact birds, especially small species such as hummingbirds, and to their conservation.
WHP Presents at the International 
Bird  Observatory Conference
Climate assessments predict that western wildfires could increase as much as 600% by 2050. In early April, WHP Advisory Committee members John Alexander and Susan Bonfield headed to the "IBOC" (International Bird Observatory Conference) hosted in Eilat, Israel to share information about our work examining ways to study habitats after fire to improve restoration efforts. 

Our work on the Angeles National Forest in Los Angeles, California includes a focused study of hummingbird use in a burn site, where we are examining the plants that  Costa's, Rufous, Allen's and Anna's Hummingbirds use and at what elevations. Our early analysis shows that 50% of their diet consisted of two plants, Yerba Santa (Eriodyction californicumand Black Sage (Salvia melliflora). Black Sage seeds, stored in the soil, are quick to emerge after a fire. Similarly, Yerba Santa  seeds may remain dormant for as many as ten years and germinate in the first year after a fire. While this species may benefit hummingbirds, it is not preferred by animals that browse. Current forest management considers removing species, such as Yerba Santa, with the use of herbicides. 

Understanding how plant species are used by different animals is critical to the conservation of diverse species, including hummingbirds. This spring, surveyors are back on the ground in the Angeles to gather more information about hummingbirds and their preferred forage species.
