The Department of Energy & Environmental Protection (DEEP) is monitoring for H5N1 in wild birds. The information we currently have about H5N1 indicates that outbreaks usually involve the death of a large number of waterfowl or shore birds, and so they are particularly interested in situations where five or more dead birds are observed. Groups or individual dead birds can be reported to them online. Individual deceased birds will not be collected or tested. You can find their recommendation for appropriate disposal and more information about Avian Flu on the DEEP website.
