are approximate only, but serve to show that the present youngsters are not safe from further attack, by any means). Observations from 10:30 A.M. to 11:10 A.M.(Misplaced due to appearance of thrashers while writing the notes).

In this song, for the first time, he introduced a couple of phrases from the Black-billed Magpies in the cage. At the end he came to me and said:"Stick to it". From the preceding note it will be seen that he must have followed me to the house and, in some way, have gathered the retinue therein commented upon, and continued the stick-to-it motive which he had just announced in the glade for the first time today.
