HABITAT USE AND MOVEMENT PATTERNS OF INCUBATING WOOD DUCKS (AIX SPONSA
) AT EUFAULA NATIONAL WILDLIFE REFUGE, ALABAMA.
Immediately after the spill, biologists observed dead fish, macroinvertebrates, mussels, turtles, frogs, snakes, muskrats (Ondatra zibethicus), wood ducks (Aix sponsa
), and belted kingfishers (Ceryle alcyon).
To determine susceptibility and immune response, we challenged 7-week-old wood ducks (Aix sponsa
) with a 1999 American crow (Corvus brachyrhynchos) isolate of WNV.
Although wood ducks (Aix sponsa
) are members of the Anatidae, their behavior differs from most other species in this family, which could affect the transmission of IAVs and APMVs.
