Busy, busy, busy in Bowerville lately. Seems the apprentices have been let loose on a few local structures. But the boss is missing. Jobs get started at one end of the main building. Some trainees work at one entrance. Others at the other. One pops up atop the walls. All squabble. All go off huffily. One hops back. Two. Three. Four. Busy, busy, busy Great Bowerbirds.
