 A friend of mine has a summer home in one of the 

 more secluded valleys of the Catskills, and every 

 June for three years a pair of catbirds have nested 

 near the house; and every day, many times, one or

 tail, with its bands of black and orange, is as active in 

 opening and shutting as a lady's fan at the opera signal-
