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,
