2:40. First observation since the preceding. Greenie, as later identified, in the nest. While the immediately following notes were know taken, I did not know which birds was in the nest. The behavior is different from that previously observed when there are eggs in the nest. G's new call from nest. At 1:58 I was sitting by the nest. Greenie called loudly and in staccato: Pittick- yer, pittick-yer, pittick-yer--pittick! Nobody came or answered. Another call. Getting impatient. At 2:15 she called again from the nest: Yerp, pityee, pityork, york, york, pityee, pityer, pityee, and left the nest, but was back in about a minute, having called again in the meantime. Calls again. At 2:18 she called again from the nest: Yerp, pityee, yerp, yerp. At 2:22 again: Pit-it-chee-ee, yerrick, twice, strongly accented the ee. Once more. At 2:22 1/2, in low tones: Tseep-perfect. Approves own call. Leaves nest. At 2:24 1/2 she left, there still being no signs of the other bird and climbed up the old oak scrapping loudly. She was back in the nest again in 3 minutes. 2 minutes after I could see Brownie coming quietly. When G saw him she made an inarticulate sound, dived out of the nest, paused by B's side without comment. B said h-a-1-h at her and went to the nest without volunteering any explanation of his failure to respond to any of the calls. G, in leaving the nest, was clearly looking for her mate and plainly showed anxiety. This is the longest time I have seen the eggs exposed in any of the five nests. Perhaps the temperature (88) has something to do with their leaving the eggs uncovered longer. Calls imperatively. B comes G was anxious. Longest exposure of eggs.
