florida gators... never threatened!

If you ain't a Gator, you should be! Alligators (and endangered crocs) are important indicator species atop their food chains, with sensitivity to pollution and pesticides akin to humans. See ESA blawg. Gator blood could be our pharmaceutical future, too. See ESA musing.


Follow the truth.

"This institution will be based on the illimitable freedom of the human mind. For here we are not afraid to follow truth wherever it may lead, nor to tolerate any error so long as reason is left free to combat it." -- Thomas Jefferson to William Roscoe, December 27, 1820.

75 Fed. Reg. 15454 / Vol. 75, No. 59 / Monday, March 29, 2009 / Notices
DEPARTMENT OF THE INTERIOR / Fish and Wildlife Service
FWS–R2–ES–2010–N028; 20124–11130000–C4
Endangered and Threatened Wildlife and Plants; 5-Year Status Reviews of 14 Southwestern Species
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of initiation of review; request for information.

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), are initiating 5-year status reviews of 14 southwestern species listed under the Endangered Species Act of 1973 (Act). We conduct these reviews to ensure that our classification of each species on the Lists of Endangered and Threatened Wildlife and Plants as threatened or endangered is accurate. A 5-year review assesses the best scientific and commercial data available at the time of the review. We are requesting the public send us any information that has become available since our original listing of each of these species. Based on review results, we will determine whether we should change the listing status of any of these species. DATES: To ensure consideration in this status review, please send your written information by June 28, 2010.

Aplomado Falcons are most often seen in pairs. They do not build their own nests, but use stick nests built by other birds. Pairs work together to find prey and flush it from cover. Aplomados are fast fliers, and often chase prey animals as they try to escape into dense grass. Parents make 25-30 hunting attempts per day in order to feed their young. Chicks are fed 6 or more times each day. Aplomado Falcons are endangered because their grassland habitat has been altered by overgrazing and brush invasion. Changing rangeland into farmland has destroyed large areas of habitat. Contamination from pesticides entering the food chain has also reduced the number of Aplomado Falcons.
