In The Auk for 1892, pp. 330-337, Mr. George II. Miickay gives a 

 capital account of the habits of this .species in our waters. lie speaks 

 of them as the swiftest flying as well as the noisiest (in the spring) of 

 ail the sea fowl which tarry with us, and gives their curious scolding or 

 talking notes as o-onc-o-onc-oiigh, egh-ough-egh. Their flight is gen- 

 erally near the water, and when shot at while flying they sometimes 

 dive from the wing. He also mentions their habit of towering, " usually 

 in the afternoon, collecting in mild weather in large flocks if undis- 

 turbed, and going up in circles so high as to be scarcely discernible, 

 often coming down with a rush and great velocity, a portion of the 

 flock scattering and coming down in a zigzag coarse similar to the 

 Scoters when whistled down."
