Peetweets make quite a noise calling to their young with alarm.

June 21.

Saw a white lily in Everett’s Pond. 

Sparrow’s nest, four eggs, deep in the moist bank beyond cherry-bird’s nest (have three), of peculiar color. She deserted the nest after one was taken. Outside of stubble, scantily lined with fibrous roots.

Clams abundant within three feet of shore, and bream-nests. 

The early grass is ripe or browned, and clover is drying. 

Peetweets make quite a noise calling to their young with alarm. 

On an apple at R.W.E.’s a small pewee’s nest, on a horizontal branch, seven feet high, almost wholly of hair, cotton without, not incurved at edge; four eggs, pale cream-color.

H. D. Thoreau, Journal, June 21, 1855

Peetweets ... calling to their young... See July 2, 1860 ("Nowadays hear from my window the constant tittering of young golden robins, and by the river fields the alarm note of the peetweets, concerned about their young"); July 2, 1853  ("The peetweets are quite noisy about the rocks in Merrick's pasture when I approach; have eggs or young there, which they are anxious about").
