It has lost most of its tail feathers.
Only two remain. Glenn Coady summarized its Toronto occurrences on
Facebook's Ontario Birds: "it
is the 23rd record for the Greater Toronto Area (including breeding
birds at High Park in the late 19th century) - and only the third
record of one into December. Yes, this species bred much more widely
throughout the northeast in the mid to late 19th century prior to
urbanization and reforestation reducing the available habitat. It
bred in the Black Oak Savannah at High Park in the 1890s between
1892 and 1899, probably every year." David Hussell in the First
Ontario Breeding Bird Atlas 1981-1985 pointed out other areas in
Ontario where Lark Sparrows formally bred: near London, Long Point
and near Sudbury. During the first atlas the only record was a pair
near Thunder Bay, which was suspected of breeding. However, the area
near Long Point where it formerly bred had no sightings.
