(555) Jan. 6th. Male is more enthusiastic "nester" About 9 A.M. both thrashers came to me at the dormitory tree. After having a few worms, both began collecting anything that looked like nesting material, Greenie to drop it almost immediately and wander off and Brownie to carry it up through the glass house to his night roost, where, in attempting to arrange it properly, all of it fell to the ground. I left him there looking as blank as the space where the "nest" ought to be and went to the glade, where Greenie was unusually tame and friendly, eating from one hand, the wren from the other. After Brownie had stared at vacancy long enough he joined the others and sat on my knee where he could get the first crack at the worms. In this respect he is very practical, but in the matter of determining when a nest ought to be built, I judge from his actions now and in the past, that he considers the proper time to be any time when there are two thrashers occupying the same territory, whereas Greenie, possibly due to the fact that the basic structure of the egg is a product of her own manufacturing plant, is less enthusiastic in off season because she does not hear the wheels revolving around inside until they start of their own accord. While Greenie does, as frequently recorded, carry twigs about at any time, the impulse is less persistent than with her mate. Brownie seems to act on the simple theory that if there are trees and bushes and another thrasher around and nesting material, the latter should be carried up into the trees. Sooner or later eggs will happen and these should be sat on for an indeterminate period of time. Jan. 7th. B clowns it. About 9:30 A.M., there being a strong north wind, nearly all of the birds were on the warm south slope. In response to call Brownie appeared at the fence below the glade and at the top of the bank. He spent five or ten minutes in futile efforts to get through the fence
