Never thought they'd eat these. It was collecting Milbert's Tortoiseshell larvae on the wall of the Stone Hut. I have watch the colony of Milbert's here since 1994. There were thousands of caterpillars on the stinging nettles that grows outside the hut where they throw all the old coals from the fireplace. Also, presumably feeding chicks or recent fledglings on this late date is interesting too.

The Bicknell's Thrush (Catharus bicknelli) is a medium-sized thrush, at 17.5 cm (6.9 in) and 28 g (1 oz). It was named after Eugene Bicknell, an American amateur ornithologist, who discovered the species on Slide Mountain in the Catskills in the late 19th century.
