THE BARROW GOLDEN-EYE. 609 



from the water, and as they rise in rapid circles to gain a view of some 

 distant goal, they sow the air with vibrant whistling sounds. Owing to a 

 difference in wing-beats between male and female, the brief moment when the 

 wings strike in unison with the effect of a single bird, is followed by an ever- 

 changing syncopation which challenges the waiting ear to tell if it does not 

 hear a dozen birds instead of only two. Again, in the dim twilight of early 

 morning, while the birds are moving from a remote and secure lodging place, 

 to feed in some favorite stretch of wild water, one guesses at their early industry 

 from the sound of multitudinous wings above contending with the cold ether. 

 The Golden-eye is a rather rare winter resident, but is better known as 

 an early spring and late fall migrant. It moves north with the Mallard and 

 the Green-winged Teal, and frequently does not retire in the fall until driven 

 down by closed waters. It is found chiefly about the most retired stretches 

 of open water or upon Lake Erie, and is exceedingly wary. The bird loves 

 chilly waters and dashing spray, and very much prefers the rock-bound shores 

 of mountain lochs, or the crunch and roar of icebergs tO' the milder com- 

 panionship of sighing sycamores and waving sedge.
