getting the worms down the throats of the chicks. In fact I have not seen them make one failure on the first attempt, whereas at nest 5, Greenie often made many failures. (15 to 20 in succession. See p. 501) Brownie, when feeding alone from the worm box, works with machine- like speed and precision, at the rate of a worm to 1½ to 2 seconds, ramming them down hard and far. The young birds seem much more vigor- ous than those in 5 at the same age and this helps, as they can keep their necks stiff.
