PM Johnston 1948 Raven 21 July Petersburg Alaska Ame's Fish Farm, Petersburg Creek A conifer near the fish house is a favorite spot for ravens to perch. Today two were per- ched on the top of the tree both rehearsing their repertoire of sounds. On other days there has been only one. There does not seem to be any significance attached to their "singing". They make these sounds while flying as well as when perched. They alight in this lone tree more than others because it affords an easy place for them to land on. One is just as likely to hear them singing anywhere in the wood as here. They have been singing in this fashion ever since I came in April. Perhaps this singing is merely the expression of an intrinsic behavior pattern. Perhaps their singing behavior is compara- able to the dropping behavior of Cal Jays or Water Owls.
