Field sparrow, Rondeau Provincial Park, Oct 15, 2018.
Not as colourful as some of the birds that come to the pond but still a nice sight.
Field Sparrows often breed more than once a season. They build a new nest each time, building them higher and higher off the ground as the season progresses. Early spring nests are often on the ground, where they’re less visible. As leaves and groundcover grow the birds build their nests in bushes and trees, where they’re safer from snakes and other predators.
