Bad News and Good…Along With Sincere Thanks

Posted

Personal and professional demands have made it necessary that Gregg Doney (left in photo) step down as Earthspan Director and Program Director of our autumn Padre Island Peregrine Falcon Survey. A long-time collaborator, Gregg has done a tremendous job since 2006 of maintaining the Survey’s scientific integrity, improving data collection methods and digitally archiving decades of field notes and band records.  He leaves the Survey in good order, and we will continue to rely on his advice regarding the direction of all Earthspan initiatives. We sincerely thank Gregg for his innumerable...

Government Shutdown Endangers Peregrine Surveys

Posted

The October 1 partial shutdown of the U.S Government closed all National Parks, Seashores and Refuges. At Assateague Island National Seashore (MD) Earthspan researchers were forbidden to enter the study area just three days after beginning our 44th annual survey. We are in place and poised to resume the survey if Congress so allows, but the migration waits for no one and our window of opportunity is rapidly passing. At Padre Island (TX) Earthspan researchers can no longer access portions of the study area on Laguna Atascosa National Wildlife Refuge, but the beachfront and State lands are...

Results in from 2012 Peregrine Surveys

Posted

Results from Earthspan’s 2012 peregrine falcon surveys have been incorporated into our annual reports for both the Assateague and Padre Island surveys. A summary of results and both reports may be found under the Research tab on this site. The life of our colleague and friend Scott Francis was celebrated at the onset of our autumn Padre survey. An immature female was captured and released at Deer Island. She was dusted with some of Scott’s ashes and released by his wife Karen to carry them along on her southward journey. The rest of Scott’s mortal remains were scattered...

Fall peregrine surveys begin in September

Posted

Scott Francis (1954-2010) As surely as summer turns to fall, Earthspan biologists gravitate to the East and Gulf Coasts to continue our four decades-plus of research on migrating tundra peregrine falcons. In Texas Gregg Doney will again lead a talented and experienced group of volunteers; in Maryland Bill Seegar and Mike Yates will add to their combined totals of 66 yearly Assateague Island surveys. They will also present a program on Earthspan’s peregrine studies to the Assateague Island Alliance on October 14. The first order of business in fall 2012, however, will be a gathering...

Polycyclic Aromatic Hydrocarbon Monitoring in Migratory Peregrines

Posted

The Deepwater Horizon Oil Spill (DWH) released an estimated 5 million barrels of oil into the Gulf of Mexico during April through July 2010. Earthspan and its partners, The Peregrine Fund and the University of Connecticut,  collected and analyzed blood samples from migrating Peregrine Falcons at South Padre Island (TX) and Assateague Island (MD) to measure pre and post-spill concentrations of polycyclic aromatic hydrocarbons (PAH) from 2009-2011.  PAHs are known to cause a variety of adverse eco-toxicological impacts that include acute toxicity, reproductive failures, DNA adducts, and...

Spring Peregrine Survey at Padre Island Begins in April

Posted

Conducted annually since 1979, our 2012 spring survey of peregrine falcons on northward migration will begin April 10. Padre Island, TX is the only known Western Hemisphere staging area for migrating peregrines in the spring, and these individuals are en route to nesting areas that encompass the entire North American Arctic. We will again be collecting blood samples for ongoing contaminant and genetic...

Fall Peregrine Surveys Under Way

Earthspan biologists are again in the field conducting our long-term Peregrine Falcon surveys (see Research). In Maryland Bill Seegar and Mike Yates embarked upon the 42nd annual Assateague Island Peregrine Falcon Survey; In Texas Gregg Doney led a team conducting the 35th annual Padre Island Peregrine Falcon Survey. Over the course of these surveys we have captured almost 14,000 Peregrines. In addition to banding and population monitoring we will be collecting blood samples for archival as well as for contaminant, infectious disease and genetic studies.
