Yellowbird building a nest.

May 31.

Another windy, washing day, but warm. 

See a yellowbird building a nest on a white oak on the Island. She goes to a fern for the wool. 

In evening hear distinctly a tree-toad.

H. D. Thoreau, Journal, May 31, 1855

A yellowbird building a nest on a white oak on the Island. See May 31, 1858 ("A yellowbird’s nest of that grayish milkweed fibre, one egg, in alder by wall west of Indian burying(?)-ground. “) See also  January 19, 1856 ("Knocked down the bottom of that summer yellow bird’s nest made on the oak at the Island last summer. It is chiefly of fern wool and also, apparently, some sheep’s wool (?), with a fine green moss (apparently that which grows on button-bushes) inmixed, and some milkweed fibre, and all very firmly agglutinated together.").and  A Book of the Seasons,  by Henry Thoreau, the Summer Yellowbird
