With all its beaches and wetlands, New Jersey is a haven for shore birds of many kinds, ranging from the smallest of Sandpipers to the largest of Godwits. Some are here year round, others pass through on their way from the Arctic to South America and back. Yet others, notably Sanderlings, spend most of the year here while making a quick trip to the Arctic for the breeding season. American Oystercatchers breed here in pairs but gather in large flocks for the winter.
