Magellanic Plover - Pluvianellus socialis - Chorlo de Magallanes
On November 14 the plovers present at Tierra del Fuego's Laguna Verde were alternating between the lake's edge and the higher gravel flats above the water line. Up among the dry pebbles, they were constantly kicking at the ground with their big pink feet, sending up a shower of debris, and then poking at the area of disturbance. On one occasion a plover used its bill to flip over a small rock, in the manner of a Ruddy Turnstone.
Speculating, it's possible that in the harsh Magellanic climate the environment is not rich enough to sustain the birds by usual sandpiper peck and grab approaches to foraging. Hence the evolution of more invasive food-gathering techniques. Whatever the case, if was wonderful to spend time watching these beautiful and fascinating birds.
