Birds of the Week # 31

Field Sparrow

The Field Sparrow (Spizella pusilla) is a small New World sparrow in the family Passerellidae. The field sparrow is distributed across eastern Canada and the eastern United States, with northern populations migrating southwards to southern United States and Mexico in the fall. The typical habitat of this bird is bushy country with shrubs and grassland. The nest is a cup-shaped construction built on the ground and hidden beneath a bush or clump of grass. The birds forage on the ground or in low vegetation, feeding mainly on seeds and insects. The population is thought to be in slow decline, but it is a common species with a wide range, and the International Union for Conservation of Nature has assessed its conservation status as being of “least concern”.

White-throated Sparrow

The White-throated Sparrow (Zonotrichia albicollis) is a passerine bird of the New World sparrow family Passerellidae. In winter, this species migrates to the southern and eastern United States. They are differential migrants with females migrating farther, increasing the proportion of females at lower latitudes in the Atlantic flyway. Females are smaller so they would not perform as optimally at colder, higher latitudes, and females avoid competition with the dominant males of the winter hierarchies by migrating farther. There is also no benefit for females to be among the first to return after winter, so migrating farther allows the males to return and establish territory a few weeks before their arrival. It stays year round in the Atlantic provinces of Canada. This bird is a rare vagrant to western Europe. Alongside some other species such as the cardinal, dark-eyed junco, song sparrow and chickadees, this species ranks among the most abundant native birds during winter in eastern North America.

  1. I was recently viewing a field sparrow online at the Cornell site so this is a treat, I love the song of the White throated Sparrow. I think stateside it is “Tom Peabody” whereas here It is “Oh sweet Canada, Canada, Canada.” Either way, it is pretty. It is as if the sparrows are playing “Peek -a-boo” with you.

    • Field Sparrows like to play around and have fun between them, as always the like to bunch together. They do things, everyday things with energy and enjoying themselves. They have no fears when while being together. Thank you, Jane. 🙂
