The Wildlife Care Center collects and maintains a huge repository of data on the problems affecting urban wildlife populations, based on the 3-4,000 animals we treat each year.
The Care Center also conducts its own internal research efforts and provides biological samples and statistical information to local, state and federal institutions that conduct wildlife research.
Ongoing Projects and Research
- Long-billed Hawk Syndrome: In April 2006, an adult Red-tailed Hawk with a severely overgrown, rotten beak was brought to the Wildlife Care Center – our first known case of Long-billed Hawk Syndrome. Staff continue to collect information about the condition and have presented findings at wildlife conferences.
- Banded Birds: The Wildlife Care Center occasionally receives banded birds. Leg bands allow scientists to track individual birds throughout their lives, a process that provides valuable information about birds’ migration, behavior and life spans.
- Parasite Analysis: The care center runs fecals (parasite checks) on all hospitalized animals and then tracks results and response to therapy.
- Lead and Injury Incidence in Raptors: X-rays are run on raptors to determine incidence of gunshot, heavy metal ingestion or other conditions diagnosed by x-ray. With funding from the Oregon Zoo, the care center also runs blood lead levelson all raptors, as well as Turkey Vultures and Ravens. The results are compared to clinical signs and radiographic evidence of metal exposure.
- Window Strike Data: The care center compiles data of window-strike birds brought to our facility to augment field research.
- Phone Call Database: Staff and volunteers are in the process of accumulating and analyzing phone call data to look for trends in wildlife conflicts and to determine where we are helping or not helping people live well with wildlife.
