Fun Nelson's Sparrow Facts For Kids

Nelson's sparrow (Ammospiza nelsoni; Ammodramus nelsoni) is a small bird that belongs to the order Passeriformes, family Passerellidae. These birds were known as Nelson's sharp-tailed sparrow along with the Saltmarsh sparrow before they were separated into two different species. They are divided into three subspecies which can be found all over America, Mexico, and Canada, which they use as a migration spot. Due to this, Nelson's sharp-tailed sparrow range is vast in nature.

These small birds forage in marshy swampland and dense vegetation whey they forage for food such as aquatic insects, small invertebrates, and amphipods. As of now, these birds are listed as a Least Concern species on the IUCN Red List but are facing a steep decline in population due to a loss of environment that is caused by deforestation and other factors such as human settlements which have led to them being displaced. Hopefully, with proper conservation efforts, these birds will get back to thriving in their natural habitat range.

Even though Nelson's sparrow is a species of birds of North America, a large breeding population is found in Canada because of the wide distribution of freshwater marshes and coastal regions.

Due to these sparrows being divided into three different subcategories their population distribution is fragmented throughout North America and Canadian provinces. Various observations have noted that these birds are migratory and will migrate to the southern Atlantic coastal regions during the winter season in search of a breeding ground and in the search for food. Due to this vast migratory range, the population of this bird is vastly distributed in both the North American and Canadian regions.

Where does a Nelson's sparrow live?

Once lumped under the same species name of sharp-tailed sparrow with the saltmarsh sparrow, these species have a wide distribution range and often go through the process of migration during the winter season as they leave their summer homes to search for a new breeding range or for newer foraging grounds. These sparrow species are often found in the southern range of Hudson Bay, all the way to the Atlantic Coast.

During the summer these sparrows migrate to northern Plains and south-central Canada. In winter, the sparrows fly along the Atlantic and coastal regions of the Gulf coast. In North American regions these birds can be found in South Dakota, Minnesota, New York, and winters from Delaware to Texas as they cross into the Canadian regions of Manitoba, southern Quebec, New Brunswick, and Maine. In South Dakota, these sparrows are often found during the breeding season and are a rare migrant species that make the state their habitat.

Who do Nelson's sparrows live with?

Nelson's sparrow is a solitary bird species and males and females come together during the breeding season. These North American birds are well-known for their vast migration range which covers large parts of North America including South Dakota, New York, Minnesota, and the Canadian region of Hudson Bay. They often fly south to the large marsh habitats crossing the Gulf Coast and the southern Atlantic coast.

Males are non-territorial and have overlapping habitats as they share a common foraging ground with other sparrows. During this migration period, these sparrows can be seen in the search for food in groups of 20-40 birds but can reach a large number of at least 100 birds in a large foraging ground.

How do they reproduce?

The sexual maturity of these birds is currently unknown. These birds have a breeding period that takes place during the spring and summer months. The males take no part in the creation of a nest and it is usually the female that makes a nest alone. The nest of these birds is located several feet above ground level to protect the nest from water fluctuations by the females.

Nelson's sparrows are polygynous in nature and have a competition to mate with each other. Males will hover over an area in the search for female companions. After finding a suitable female, the male will attempt to mate with her in a forceful way. The females, if unreceptive, will shrug the males off and fly away. Since they are polygamous, several males will try to mate with a female in a short period. Even though the mating is somewhat forced, receptive females will crouch and prepare herself for copulation if she is receptive of a male. After copulation, the females will lay two to six eggs in early summer. The incubation period for the eggs is 10-11 days and after a further 11-12 days, the young can leave the nest.

What is their conservation status?

Currently, Nelson's sparrows have a status of a Least Concern species on the IUCN Red List because of the vast habitat range that makes up a large population of these birds of North America. However, even though they are estimated at a stable population range, they are slowly losing their numbers due to human interference which leads to habitat loss. The conversion of marsh and grassland for domestic and agricultural purposes has led to them being displaced from their marsh habitats.

As a migratory species of birds, Nelson's sparrows are protected under the United States Migratory Bird Act.
