Lincoln's sparrow.



Lincoln's Sparrow, Rondeau Provincial Park, Ontario, Canada, October 28, 2023.

A semi-regular fall visitor to the yard and water.

Sometimes, singing a beautiful song might not be enough to win over a female. In a laboratory study, female Lincoln's Sparrows were more attracted to males that sang during colder mornings more than those singing during warmer mornings. This may be because males singing in the cold showed off more than just their song; singing in the cold requires more energy and could mean that males singing in the cold would make better mates.

Sam seemed quite upset over the blow to feline superiority.
