On June 15th of this year, I found a field sparrow nest with four eggs, tucked neatly into a small gray dogwood bush. This nest was located where we might predict given the time of year, based on how close to the ground it was and the relatively sparse vegetation surrounding the nest.
Beyond nesting, field sparrows have developed an interesting trick to produce more offspring. Male field sparrows will often sing at night, and researchers sought to understand why a mostly diurnal bird might belt out song in the middle of the night. In fact, these birds were meeting extra-pair mates. Females responded to these songs mostly when they were reproductively ready and fertile. Wrapped in the dim light of the strawberry moon, field sparrows break their largely monogamous ways.
You can find field sparrows throughout Faville Grove Sanctuary, though the best spot to see the birds is east of North Shore Road. Arriving in early April and leaving sometime in October, these birds actually grace the landscape for a majority of the year with their white eye ring and distinctive pink bills. Right now you might be able to find recently fledged young, perhaps a second brood, foraging through shrublands and brush.
