A familiar sparrow that can be found throughout North America, song sparrows are often seen singing cheerfully while perched on a tree branch or telephone wire.  The species is present in most of their range year-round, although northern populations migrate to the southern United States and Mexico for the winter.

Physical Description

Overall, song sparrows are medium-sized, plump songbirds with rounded heads and long, rounded tails. Plumage varies based on geographical region. However, adults in many subpopulations have upper parts of their body that are chestnut brown or russet brown, with pale gray or creamy white chests and streaked breast with a characteristic dark breast spot.  

Size

Among adults, length can range from 4.3-7.1 inches (11 to 18 centimeters), with a wingspan between 7.1 and 10 inches (18 to 25.4 centimeters) from tip to tip. 

Native Habitat

Nesting grounds include open woodlands, shrubby fields and wet areas with dense foliage. They are also commonly found in areas with human development, like suburban parks or backyards.

Communication

Male song sparrows sing to attract females and to establish their territory, which they will defend against other males who intrude. They have a wide variety of vocalizations they use in their songs, which are a combination of repeated notes mixed with chips, trills and buzzes. Their songs differ based on their geographical region. 

Food/Eating Habits

Song sparrows forage for food on the ground or among vegetation, pecking and hopping while looking for small insects and seeds to eat. Their eating habits also vary based on geography. For example, populations that live among wetlands and coastal areas will search in very shallow water for small crustaceans, and sometimes fish, to eat. 

Social Structure

Male song sparrows establish territory during the nesting season, and do not like sharing with other males. However, these territories are relatively small so a resource-rich habitat will often contain many song sparrows living near one another.

Reproduction and Development

Nests are usually constructed on the ground among shrubs or in a clump of weeds, although they will sometimes build nests higher off the ground.  Their nests are cup-shaped and are lined with twigs, grasses, leaves, and animal hair. Females lay clutches of between three and five eggs that are light colored with brown to red-brown spots. 

Females incubate the eggs for about 12-14 days. Both parents help with care and feeding for the nestlings, who are ready to leave the nest for the first time about 10 days after hatching, although they will remain with their parents for two to three more weeks before they are ready to live on their own.

Song sparrows are known to re-nest in the same location for multiple years.

Conservation Efforts

Populations in North America appear to have declined since the 1960's, although they are still quite abundant. In addition to habitat loss, song sparrows are vulnerable to common threats like window strikes and predation from other animals, such as hawks and domestic cats.

Help this Species

  • Reduce, reuse and recycle — in that order! Cut back on single-use goods, and find creative ways to reuse products at the end of their life cycle. Choose recycling over trash when possible.
  • Be a smart consumer. Choose products made with sustainable ingredients, such as Smithsonian certified Bird Friendly coffees, which support farmers striving to limit their impact on wildlife and habitat.
  • Avoid single-use plastics, such as plastic bottles, bags and utensils. Choosing reusable options instead can help reduce plastic pollution.
  • Plant native flowers in your garden to help feed resident and migrating pollinators. You'll make your lawn beautiful and help wildlife at the same time!
  • Less is more. Cut down on the demand for resources by consuming less. Buy only what you need, and look for pre-owned or repurposed items before purchasing something brand new.
