Birds & Wildlife

Sussex County, NJ hosts several recognized Important Bird Areas and Natural Heritage Priority Sites.

The fields, meadows, ridge tops and hillsides of the Sussex Skylands provide excellent habitat for Yellow-bellied Sapsuckers, Red-shouldered Hawks,  Great Horned Owls and Bald Eagles.

Important Bird Areas (IBA) are sites, identified by the National Audubon Society, that provide essential habitat for one or more bird species that are either threatened, endangered, or vulnerable due to a restricted range, restricted habitat type/biome, or high densities due to their "congregatory behavior." An IBA's significance is prioritized as either global, continental, or state.
