in the open street rapidly toward home; so they both were over there. At the entrance they separated, Nova to the oaks at the east end and B to the glade, where he immediately began digging. In a few minutes he started up the old oak, but instead of going to the top and singing loudly as expected, he went up only about 7 feet and sat in a dense clump of foliage and sang very softly. This, however, brought Nova (notwithstanding my nearness) who joined him, whereupon he began shaking the twigs with his bill and stopped singing.
