The usual early morning full song and calls. About 8:30 A.M. the duck-like flutings first noted on were heard issuing from amongst the rhododendrons near the tool house. Brownie was soon seen and came for worms, continuing to make this call as he sat on my hand. He was being answered in exactly the same phrases from an oak and it was seen that Nova (?) at any rate another adult, was sitting in plain view about 20 feet away watching the performance. A conversation between B and Greenie was noted last year which, like this one, contained no other theme. I am not certain now, in my identification of Nova at all times, and the thought occurs that it might possibly have been another bird, even Greenie. When B had finished he ran to the dormitory tree and was followed by this other bird promptly. Reference to last year's notes at this same period will show that happenings in the dormitory tree now are paralleling closely, both in kind and date, those of last year which finally resulted in the Oct- obr-November brood. That nest last year was No.5, two being failures If one is built this year, it will be NO. 4 for this year, one being a failure. This would make it look as if Brownie plans to have three broods per year. Checking recollection of pitch. In looking over last year's notes of Sept.-Oct I found where I had endeavored to check my recollection of the pitch C3. I tried it again just now and found that I was between C3 and C3#, there being a slight beat with either. About 11:30 Brownie was chasing Bb through the upper branches of the trees, but being easily avoided. Bb scolded and kept about 10 feet off, stopping when B stopped and watching him in no friendly manner. If B would only let him alone, he would be just as tame. About 11:45 B was actually making additions to his platform and Nova was scrapping from the old oak. It looks like a serious effort at another nesting cycle.
