| Comments: The Texas Henslow’s
Sparrow has been extinct since 1983. It was found only on a 105 acre field
near Houston, Texas. It nested in weedy fields or pastures, preferring
moist areas. It built it’s nest in tall grass, often with a partial roof,
which offers some seclusion. It lived primarily on insects, including
slugs and spiders and seeds from grasses and sedges. It found most of it’s
food sources while foraging on the ground.
Preservation of the species was complicated by the
dispute on whether it was a "true" subspecies of the Henslow’s Sparrow
found 750 miles away in the southern Missouri in 1973. While the debate
continued the subspecies fell into extinction, it’s habitat encroached
upon and was finally declared a "true" subspecies in 1983 and "Federally
Endangered— presumed extinct". The question whether the Texas Henslow’s
Sparrow is a true subspecies is still somewhat controversial because of
the difference in distinguishing characteristics between the sub and
parent species. Today, the Henslow’s Sparrow is approaching the endangered
list and hopefully more care will be given in saving the parent species. |
