[[circle]] 223 [[/circle]] [[underline]] scoresbii [[/underline]], Dec, 31, 1955, II. Another L.C. performance, by adult in complete or almost complete winter plumage. HD (notes harsher than those previously described, more or less "Keeearr Keeearr" [[image-arrow pointing to the right]] O (very brief, only one note) [[image-arrow pointing to the right]] T with T note [[image-arrow pointing to the right]] T with T note. The fact that HD may occur without, or with very little O, might suggest that the difference between HD and O is something more than a pure "intensity" difference. I have seen several very slight R's of mantle feathers after attack. By birds in semi-V or continuing feeding, (adults of all stages and juvenals). Only in the case of one juvenal, however, was this R at all conspicuous. December 31, 1955, Porvenir Bay. [[underline]] maculipennis [[/underline]] A lot of miscellaneous stuff seen today. A flying bird, with food in its bill, chased by Kelp Gull. Much twisting and turning, finally forced to drop food. Then flies away, uttering long-drawn LCN notes "Keeeeaar keeeeeaar." These sounded very high intensity; rather less quavering, however, than the notes I called PCC notes yesterday. (Actually, I doubt if anything like real PCC notes should be distinguished in this species. [[underline]] The notes I have been calling PCC notes, although almost certainly homologous with the PCC notes of other species, are probably nothing more than high-intensity LCN's in this species [[/underline]]). The interesting thing about this performance, however, was that [[underline]] the first 2 long notes were delivered from an extreme aerial O posture [[/underline]]!!! [[image-drawing of bird with beak open and head at upward angle]] Accompanied by beating wings. Merged smoothly into a series of 3 progressively shorter notes, progressively deeper in pitch, as the bird circled and landed (Thus the whole series of notes can hardly be called a complete aerial Long Call - the last half was a Landing Call).
