Two eggs. A little later, when the shift was changing, it was noted that there were two eggs in the nest. Since the first egg was laid the nest has been continuously occupied by one or the other of the birds. 7:15 P.M. Everything proceeded according to schedule during the rest of the day, as far as witnessed. There has been little singing of any kind since the eggs were laid. March 3rd. At 8:15 Greenie was in the glade and relieved B after she had had a few worms. B came to me at once, but shortly climbed into the oak behind me, where he sat looking off over the country. During this time B uttered not one syllable, but G notified him that she was the going to take over by sounding "bluebird" call as she approached the nest. At 9 B was in the nest, and as I stood watching him and giving him an occasional worm, the wren came and demanded his share. The wrens have elected to build their nest in the tool house where they will be disturbed every time anybody enters, which is often, and a door or a window will have to be left open for them. The nest is only about 2 feet above the floor, between two studs, on top of a cleaning cloth which is kept there, and behind the strainer (hang- ing on the wall) that was used as a substitute for Thrasher nest used every day, NO.5. The garden tools, are all about it. One of the birds is very wild and dashes against the windows when anybody enters; the other is the tame one. There are also numerous mice about. Although a very comfortable location, it is unfortunate in many respects, and I am surprised at their choice. They examined all the houses, holes in stone walls and in banks and even the astronomical telescope mounting in the tower (where they were seen to carry feathers). Sev- eral of the locations had been used by them (or their predecessors) in previous years. Wren's nest.
