WOOD DUCK

The Wood Duck is a common statewide breeder. This cavity nester prefers marshes with dead trees, wooded ponds, and flooded bottomland woods. This once rare species has rebounded considerably during the past eighty years. Data on this species is poor, but BCN trends show a significant increase. This species is under-sampled by the BCN Survey which does not concentrate on marshland areas. Photo: Dave Menke / USFWS
