Jan.25th. to 28th. incl. During this period Brownie's full song has increased in frequency, beginning about sunrise and being heard at fairly fre- quent intervals up to about 3 P.M. Its character is somewhat fragmentary and imperative with a tendency toward harsh phrases.

When I talked to him he would whine, but he would not come down for meat, though plainly considering the matter. Several times I walked off about 50 feet and each time I returned he would
