589 At intervals during the forenoon, I visited the nest, each time finding Brownie either working in it or getting material, very friendly and hungry. He has abandoned the cramped corner and adopted my sub-structure, apparently with enthusiasm. The nest is growing rapidly and, in ground plan, is like a figure eight with one loop about four times the diameter of the other. The small loop is Brownie's work antedating the acceptance of my plans. 1:25 P.M., as I approached the nest, Brownie flew up to my hand while I was still in the road. When he had had all the worms he wanted, he took three in his bill to the nest, where I was just in time to see him give them to his mate. A few minutes later, when he again returned to the nest, I handed him three twigs in succession, each of which he took from my hand and incorporated into the structure. This is the beginning of the second observed annual nesting cycle of this same pair. The first actually observed work on Nest No. 1 last year was on Feb. 19th. I am inclined to think that work actually began earlier. Notes of Feb. 12th., 1932, singularly enough, show material being carried up into this same tree for the first time. Indications to date tend to show that: (1) This pair is probably mated for life, and (2) February is their normal time to begin nesting in earnest So far the male has done nearly all of the building on this nest. There is very little singing at present. During the last three days, Brownie has shown a little intolerance at times, toward birds eating from the dishes in the glade or in that part of the tree where the nest is located--perhaps 5 or 6 times. He has been very mild about it, however. B working faithfully. Present form B takes twigs from hand and uses. Feeds G. Second annual nesting cycle. Generalizations. Defense of nest?
