Distribution and Movement (Migration etc.) |
|
| Normal | Amazonetta
brasiliensis brasiliensis Eastern Columbia, northern and eastern Venezuela,
Guyana, northern and central Brazil Movements: Amazonetta brasiliensis brasiliensis sedentary, but southern Amazonetta brasiliensis ipecutira birds move north in winters, into the range of Amazonetta brasiliensis brasiliensis |
| Occasional and Accidental | -- |
| Introduced | -- |
| Inland, pools, streams, marshes and small lakes in dense woodland, also flooded fields, rarely in brackish or saline waters (coastal lagoons and mangroves) (B1, B8, B19, B25, B26) |
Intraspecific variation |
| Amazonetta brasiliensis brasiliensis
from Eastern Columbia, northern and eastern Venezuela, Guyana, northern and central Brazil
is smaller and non-migratory; Amazonetta brasiliensis ipecutira from eastern Bolivia and southern Brazil to northern Argentina and Uruguay is larger and southernmost birds migrate north in the winter. (B1, B3, B6, B8, B25, B26) |
