When cattle egrets have no cattle
Today we tackle the thorny question of what cattle egrets do when there are no cattle (or horses, or sheep, or goats, or lawn mowers) around. They accompany these various animals and machines to feast on insects and small animals disturbed by the grazing.
When they don’t have others to stir up these things, they do it themselves. This group of cattle egrets methodically combed a scrubby field, eating as they went. As they moved across the field, birds from the back would fly forward and take up their position at the front. By the time a line of birds ended up at the back of the bunch, they’d probably scoured their section of field of easy pickings, so they leapfrogged to the front again.
When they reached the fence at the end of the field, they moved higher on the hill and began the whole process again. Finally, they reached the top of the hill and, after a while took off, first in ones and twos, and then in greater numbers until they had all gone.
