Horned lark.

Not much variety in bird species in the yard these days. Went out looking for snow buntings and horned larks but nothing came close enough to photograph. This one is from the archives. January 14, 2015, Kent county, Ontario, Canada. Eremophila alpestris. Female Horned Larks often collect “pavings”—pebbles, clods, corncobs, dung—which they place beside their nests, covering soil excavated from the nest cavity. The “paved” area resembles a sort of walkway, though the birds don’t seem to use it that way. While nobody fully understands the function of these pavings, they may help prevent collected nesting material from blowing away while the nest is under construction.
