The final aspect <strong>of</strong><strong>Spectacled</strong> <strong>Eider</strong> recovery will involve <strong>the</strong> formulation <strong>and</strong> testing <strong>of</strong><br />
specific hypo<strong>the</strong>ses about <strong>the</strong> cause(s) <strong>of</strong> <strong>the</strong> eiders’ decline <strong>and</strong> <strong>the</strong> importance <strong>of</strong> specific<br />
obstacles to recovery. To date, several hypo<strong>the</strong>ses have been suggested to account for <strong>the</strong><br />
decline <strong>of</strong> this species, <strong>and</strong> <strong>the</strong> <strong>Service</strong>’s prioritization <strong>of</strong> <strong>the</strong>se preliminary hypo<strong>the</strong>ses has<br />
guided much <strong>of</strong> <strong>the</strong> ongoing exploratory data collection. At present, however, data are<br />
inadequate for rigorously developing <strong>and</strong> quantitatively testing most <strong>of</strong> <strong>the</strong>m. In addition, <strong>the</strong><br />
relatively few data pertaining to <strong>the</strong>se hypo<strong>the</strong>ses have yet to be comprehensively summarized<br />
<strong>and</strong> evaluated.<br />
To make substantial progress toward recovery, it is imperative that all research be designed<br />
<strong>and</strong> implemented within a hypo<strong>the</strong>sis-testing framework. The current lack <strong>of</strong>data, however,<br />
should not be construed as an excuse for unfocused data collection during <strong>the</strong> exploratory<br />
phase, nor should all hypo<strong>the</strong>sis refinement be postponed until <strong>the</strong> end <strong>of</strong>exploratory<br />
investigation. As data become available incrementally, <strong>the</strong> hypo<strong>the</strong>ses should be increasingly<br />
fine-tuned. Whenever possible, <strong>the</strong> <strong>Service</strong> should evaluate hypo<strong>the</strong>ses on <strong>the</strong> basis <strong>of</strong> existing<br />
data <strong>and</strong> summarize <strong>the</strong>se evaluations in <strong>the</strong> form <strong>of</strong> <strong>of</strong>ficial position papers. These summaries<br />
will be essential for prioritizing work plans to ensure that scarce dollars <strong>and</strong> human resources<br />
are consistently applied to <strong>the</strong> most viable <strong>and</strong>/or most easily-tested hypo<strong>the</strong>ses. Exploratory<br />
data collection <strong>and</strong> hypo<strong>the</strong>sis-testing are concurrent processes, with improvements,<br />
refinements, <strong>and</strong> evaluations <strong>of</strong> <strong>the</strong> latter task ultimately being contingent upon successful<br />
completion <strong>of</strong> <strong>the</strong> former one.<br />
Over <strong>the</strong> next several years, recovery efforts should focus on <strong>the</strong> following topics:<br />
a. Management Actions--Although limited in scope, a suite <strong>of</strong> management actions is<br />
available that could reduce <strong>the</strong> rate <strong>of</strong> <strong>the</strong> <strong>Spectacled</strong> <strong>Eider</strong>’s population decline <strong>and</strong> pave<br />
<strong>the</strong> way for recovery once <strong>the</strong> obstacles have been identified. Most specific tasks fall into<br />
four broad categories: (1) reduction <strong>of</strong> eider mortality; (2) development <strong>of</strong> ownership in<br />
recovery through increased dialogue <strong>and</strong> Memor<strong>and</strong>a <strong>of</strong> Agreement; (3) Section 7<br />
consultations <strong>and</strong> permitting; <strong>and</strong> (4) development <strong>of</strong> captive flocks.<br />
Confirmed sources <strong>of</strong> eider mortality include lead poisoning, predation, human harvest,<br />
injury, <strong>and</strong> researcher impact. Since <strong>the</strong>se sources <strong>of</strong> <strong>Spectacled</strong> <strong>Eider</strong> mortality operate<br />
on <strong>the</strong> breeding grounds, <strong>the</strong> people who share <strong>the</strong> l<strong>and</strong> with <strong>the</strong> eiders must be intimately<br />
involved in <strong>the</strong> recovery process. Current dialogue must be exp<strong>and</strong>ed to develop a<br />
common underst<strong>and</strong>ing <strong>and</strong> cooperation essential to effect recovery. Through Memor<strong>and</strong>a<br />
<strong>of</strong> Agreement, <strong>the</strong> <strong>Service</strong> involves in <strong>the</strong> decision making process local governments,<br />
Native organizations <strong>and</strong> villages, <strong>the</strong> ADF&G, <strong>and</strong> <strong>the</strong> National Biological <strong>Service</strong> in<br />
developing <strong>the</strong> most effective strategies to achieve reductions in eider mortality. If<br />
appropriate, <strong>the</strong> Memor<strong>and</strong>a <strong>of</strong>Agreement for managing marine mammals <strong>and</strong> <strong>the</strong> Yukon-<br />
Kuskokwim Delta Goose Management Plan could serve as models for eider agreements.<br />
