Ornithologist: This bird species is widely thought to subsist primarily on vegetation, but my research shows that this belief is erroneous
While concealed in a well-camouflaged blind, I have observed hundreds of these birds every morning over a period of months, and I estimate that over half of what they ate consisted of insects and other animal food sources
assumes, without providing justification, that the feeding behavior of the birds observed was not affected by the ornithologist's act of observation
