Over a ten-day visit to Guadalupe in the early summer of 1897, members of the US Commission of Fur Seal Investigations encountered a single Guadalupe Towhee, which they collected. It seems unlikely that that bird was the final survivor of its subspecies, but it was the last ever seen by scientists. Even by island standards, Guadalupe suffered dramatically as a result of the introduction of goats and house cats, and by the middle of the twentieth century, observers were no longer as much surprised by the towhees\u2019 extinction as by the fact that the bird had ever been able to exist on a piece of land now so thoroughly devoid of \u201cshrubs or understory of any kind.\u201d Whether the last towhee fell to habitat loss or the claws of a feral cat will never be known, but it is certain that the Guadalupe Towhee has been extinct for a century or more.\u00a0<\/strong><\/p>\n\n\n\n

Behavior:\u00a0<\/strong>Palmer found this \u201cnot abundant\u201d bird around \u201cbrushwood, fallen logs, fences, etc., rather than trees,\u201d where they fed on both insects and seeds. Like other large sparrows, he noted, “Their method of scratching among fallen leaves is curious: they make a jump forward, at the same instant strike back with both feet.”<\/p>\n\n\n\n
