446 Sherman, Brewster's Warbler in Massachusetts. [oct' 



Arboretum Brewster's of 1908. They were white, speckled with 

 irregular patches of brown ; more heavily on the larger end. Each 

 egg lay with its smaller end towards the center of the nest. 



June 21. I visited the nest from which the mother bird flew. 

 Knowing incubation must be nearly completed I went away as 

 quickly as possible. 



June 22. After supper I went to the nest and found the four 

 eggs hatched, and such helpless mites. Too helpless to move. 



June 24. The female flew from the nest on my going to it. The 

 young were nearly twice the size as last seen. The male Golden- 

 wing was busy carrying green caterpillars to them. 



June 25. The female was still brooding. The young had wing- 

 feathers one quarter of an inch long, and the general development 

 was very marked. 



June 26. I found both parents away. This afforded me an 

 excellent opportunity to look at the nestlings closely. Both 

 parents soon returned bringing two green caterpillars each. These 

 the babies soon devoured. Their eyes had opened and their 

 daily increase in size was very noticeable. 



June 29. The young were covered with an olive down above, 

 and so crowded in the nest that only their heads and backs were 

 visible. I put my hand over the nest. Not a sound came from 

 it and none attempted to leave it. The mother bird was away but 

 returned without food. 



Early Thursday morning, June 30, the nest was empty. I could 

 not imagine those helpless looking nestlings of the night before, 

 winging their way out into the world, and feared some accident 

 had befallen them. Although there were no signs of either of the 

 parents about I determined to wait a while. Soon I was rewarded. 

 The mother bird came, bringing two green caterpillars which, 

 on seeing me, she swallowed; and leaving the tree, on which she 

 first perched, she flew unconcernedly about for some time. 



Finally she went into a tree with intervening trees between us. 

 Closely watching her vicinity, I saw her drop into the tall grass 

 for a second and fly up onto the tree again. Twice she did this, 

 but so quickly that I could not see whether she had food or not. 



Going to the places where she dropped I found two fledglings. 

 From further watching, I concluded the other two were in a clump 

 of blackberry bushes growing in a rock heap.
