The rare mustached sparrow.

House sparrow, Oct 18, 2020, Rondeau Provincial Park, Ontario, Canada.




Maybe this is its halloween costume.
Passer domesticus
The House Sparrow was introduced into Brooklyn, New York, in 1851. By 1900 it had spread to the Rocky Mountains. Two more introductions in the early 1870s, in San Francisco and Salt Lake City, aided the bird’s spread throughout the West. House Sparrows are now common across all of North America except Alaska and far northern Canada.
