 breeding duties, leave the further care of the offspring to the females. 



The Knots arrive in Greenland in full summer plumage. The 

 feathers on the back and the crown of the head by wear and tear 

 in summer alter their colour to some degree as the pale edges of

June 8"» and 9"' 1908 I visited a large moor far inland — N. of 

 the mountain Trekroner — and observed here 30 to 40 couples 

 of Dunhns. The localities here were as attractive to the bird as
