2024 Autumn Peregrine Surveys Complete
Bill Seegar and Mike Yates conducted the 54th annual autumn Peregrine Falcon Survey at Assateague Island, MD and Gregg Doney the 47th annual autumn Survey at Padre Island, TX. 2024 Assateague numbers were poor overall but even more so when viewed by unit effort: Sightings were our 7th lowest and captures our 3rd lowest among the 54 survey years. Among sightings, confirmed adults were only 30% of our 54-year average and juveniles 53%. We captured no full adults, only second-years. Three of our 27 captures were not tundra peregrines at all but eastern peregrines banded as nestlings, and a...

Read MoreEarthspan Studies Avian Influenza with Utah State
We began a collaboration in December 2022 with Arnaud Van Wettere (DVM, MS, PhD, DACVP) at the School of Veterinary Medicine, Utah State University. We are providing plasma samples from hundreds of peregrines captured at Assateague and Padre Islands. Entitled Prevalence of Avian Influenza A Virus Antibodies in Migrating North American Peregrine Falcons, the investigation is summarized thus: An outbreak of highly pathogenic avian influenza (HPAI) virus H5N1 started in the fall of 2021. The scale of this outbreak is unprecedented; it is the largest and most prolonged to date in the USA....

2021 saw a return to the field for Earthspan biologists after a 2020 field season lost to COVID. A spring survey was conducted at Padre Island and fall surveys at Assateague and Padre Islands. Please see the Research tab for result summaries and full reports on the surveys.
Read MorePadre Surveys Resume
As life slowly returns to normal, vaccinated Earthspan biologists returned to Padre Island in April. Gregg Doney, Chris Pfister, and Sam Voss ably conducted the surveys. We were honored and encouraged by the interest and enthusiasm of Olive Hershey and Kent Burnett during a survey visit that Geoff Pampush of The Peregrine Fund organized. Full surveys at both Assateague and Padre Islands are planned for the fall.
Read MoreFall Peregrine Surveys Canceled
It is with great regret that we have decided to stand down from the fall 2020 peregrine surveys at both Assateague and Padre Islands. The continued prevalence of COVID-19 makes the travel and interactions necessary to properly conduct the surveys a risk we cannot accept. We will continue to respond appropriately to this deadly virus, hope all our fellow citizens will finally do so, and plan to survive and resume this important work in 2021. The long-term nature of our studies will minimize the effects of our first such absence since the surveys were begun in 1970 and 1977. In the meantime,...
Read MoreCOVID-19 Prompts Cancellation of Spring Padre Island Survey
We’ve been keeping up with the latest developments on COVID-19 and consulting with colleagues in the medical and research communities. We’ve also watched the dominoes fall through travel bans, cancellations of gatherings and sporting events, suspension of classes at schools and universities, and work-at-home transitions among workplaces. It is with great reluctance and regret that we’ve decided to cancel the spring survey for the first time since its inception in 1979. We cannot justify placing our biologists at risk for the sake of the 50-60 falcons we could capture. The...

The FOM (Field Operations Manager, as he was affectionately called by many of us) has left the building. A founding member of Earthspan, Bill Mattox mentored us in Greenland and was a touchstone in the lives and careers of countless biologists. He has our eternal thanks, and will forever be missed.
