Wilfred J. Caron was a quizzical man. He owned a Christmas tree farm in Old Mystic, Conn., right on U.S. Route 1. His ramshackle house was painted pink, with green signs out front, an old cemetery nearby, and new housing development crowding the land on all sides. When I met Mr. Caron, his Christmas trees had grown beyond the reach of his shear and were fast becoming a forest.

The question all the people that are sharing the Baltimore orioles on Lambert’s Cove Road, and now one in Oak Bluffs, are asking is, why are they still on Island? There are two answers, and they both have to do with genetics. Unlike many of the waterfowl that learn how to migrate from their parents, passerines or dickie birds are programmed by the genes of their parents. Therefore orioles, which are passerines, can innately navigate to their wintering grounds in Mexico and Central America. However sometimes there is a glitch in these inherited programs and either the young birds remain in their summer digs or, more commonly, a youngster makes a 180-degree turn and reverse migrates. So the Baltimore orioles here on the Vineyard were either born here and didn’t leave this fall, or came from points south. Unfortunately most of these birds will not survive the winter — although some do. The crew on Lambert’s Cove seems bent on keeping the young male alive with oranges and jelly! Good luck.

If skies are clear, stargazing will be great into next week. Tonight will be moonless; the moon is in the New Moon phase and too close to the sun to be seen. The moon won’t interfere until late in the week.

Curious, it is, that while some trees evoke only a shrug, others inspire speculation, and exploration, and great trans-Atlantic expeditions, and stir the very highest of hopes. Consider the sassafras.
