September 12 
{^esterday was an off day for birds. We saw very 
few of them anywhere. Evidently the heavy flights of the 
9th and 10th passed quiclly on. Another and rather con¬ 
siderable wave arrived last night. It was composed almost 
wholly of Black-polls. We saw or heard them nearly every¬ 
where, In the morning they were scattered and exceedingly 
restless. We repeatedly saw them rise high in air and 
fly off over the woods towards the south as if starting 
on migration. Migrants of other kinds were noted moving 
south. About 9 A, M, IhreB Chimney Swifts and a Barn Swallow 
passed over the farm-house with a dozen or more Black-polls 
streaming after them. 
Just before noon as H. W. Henshaw and I were 
standing in the garden at the rear of the farm-house, we 
heard tvdce, at first rather faintly but the second time 
loud amd clear, and apparently coming from directly over¬ 
head, the unmistakable flight call of a Golden Plover — 
the double, rolling note, falsetto in tone yet distinctly 
musical or, at least, very pleasing to the ear, especially 
of an old sportsman. It may be written cru- e. The bird 
seemed to be flying southward and at no great height, 
but we could not see it. The sky was filled with low- 
scudding, billowy clouds at the time. 
In the early afternoon we found about fifty Warblers 
among the gray birches in Birch Field. All that we iden¬ 
tified save two were Black-polls. One of the exceptions 
was a Chestnut-sided Warbler, the other an Oven-bird,^
