Two Mississippi kites flew by Mass Audubon's Pilgrim Heights Hawk Watch last week. The passage of a few of these aerially insectivorous southern hawks has become a regular spring event at Pilgrim Heights.
Another southern visitor, a summer tanager, was seen in a yard in Harwichport, and a red-headed woodpecker was reported from Wellfleet.
The previously reported tricolored heron was still at South Cape Beach as of May 10th.

Common and least terns have returned this week, ready to provide the ambient beach sounds for another summer on Cape Cod.
