The absence of recent records is paralleled both on the East and West Coasts, but it is possible that populations are persisting at low levels of abundance. For now, we will treat the population as established. The latest record that we have for the Hudson River was in, 7/18/2014, at Norrie Point, State Park, at Norrie Point State Park/NY/Indian Kill (7/18/2014, Hudson River Alamanac https://content.govdelivery.com/accounts/NYSDEC/bulletins/c7a56b, 41.840248 -73.930992)
