JPMeyers 1943 1974 1973 02 1974 01 Hudonian Godwit Estancia Medeland, 35 km Saf Junncho by road, Pcia de Buenos Aires, Argentina 11 November in short grass field-one where I found first big flock of traffic - where I solve # godwit plus a nearly flock of 7. Disturbed them before I could see what they were doing. Arroyo Chico, Estancia Medeland, 35 Km S of Juvancho by road, Pcia de B.A., Argentina 23 November godwits spread sparsely along Arroyo, foraging above (1) water line. 3 birds circling in a circle around a cow pie, tearing it apart. Now we know why H godwit have such long bills - to keep their heads above the sluit. Found a cowpie up in the field completely torn apart - maybe Godwit work. Tower Llanos, Estancia Medeland, 35 Km S of Juvancho by road, Ptdo de Madariaga, Pcia de Buenos Aires, Argentina 22 January went to tower at 1800, found flock of 7 H.G. on grid 4. While placing stakes in area for Grid 10, at base of tower, found several cowpie with 1/8 - 1/4 inch holes. Up to 30 such holes in a pie (former). Remarkable work of Godwit 23 January 0700 (ADST) H.G. flew onto Grid 10, began foraging in cowpie 0705 H.G. chasing Golden flower away from a cow pie on Grid 4. Several godwits on 4; all of them are feeding in cowpie, working them over for several minutes at a time. Bill entering as far as to the base of the culmen, although much of the tissue it goes in lies far. Only one godwit / cowpie - chase each other off. In fact it looks as if one godwit protects second cowpie within 1/4 its vicinity. Trivial? 0920 - godwits on many pieces of cow pies. 1 bird sticks bill in one spot, dips continuously in a style similar to that used in 1960. Angle of bill varies from almost horizontal to almost vertical. More vertical angle = less of the bill immersed. But right now a bird is going in vertical w/ bill up to nostrils! This particular bird worked on one pie for 3 mins, now moving to an adjacent one. 1440 - seen a considerably amount of its aggression today - affect the form of which strongly suggests territoriality (I am sure that it is because of the consistency with which individuals defend particular areas. The behaviors of approaching H.G.'s is intriguing; just now,
