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.

74 Fed. Reg. 40649-40683 (August 12, 2009) / Volume 74, Number 154 / Proposed Rules
DEPARTMENT OF THE INTERIOR Fish and Wildlife Service / 50 CFR Part 17 / Endangered and Threatened Wildlife and Plants; Listing Seven Brazilian Bird Species as Endangered Throughout Their Range; Proposed Rule
ACTION: Proposed rule.

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), propose to list the following seven Brazilian bird species and subspecies (collectively referred to as ``species'' for purposes of this proposed rule) as endangered under the Endangered Species Act of 1973, as amended (Act) (16 U.S.C. 1531 et seq.): black-hooded antwren (Formicivora erythronotos), Brazilian merganser (Mergus octosetaceus), cherry-throated tanager (Nemosia rourei), fringe-backed fire-eye (Pyriglena atra), Kaempfer's tody-tyrant (Hemitriccus kaempferi), Margaretta's hermit (Phaethornis malaris margarettae), and southeastern rufous-vented ground-cuckoo (Neomorphus geoffroyi dulcis). This proposal, if made final, would extend the Act's protection to these species. The Service seeks data and comments from the public on this proposed rule.
DATES: We will accept comments received or postmarked on or before October 13, 2009. We must receive requests for public hearings, in writing, at the address shown in the FOR FURTHER INFORMATION CONTACT section by September 28, 2009.

The Brazilian merganser occurs in a few fragmented locations in south-central Brazil, including the upper-tributaries of rivers within the Atlantic Forest biome and to the east in the Cerrado (savanna) biome. The species is a diving duck that occurred historically in riverine habitats throughout southeastern Brazil, northeastern Argentina, and eastern Paraguay.  Currently, the species is found in extremely low numbers at six highly disjunct localities, and its largest subpopulation is estimated to contain fewer than 50 individuals.
