NAME: ‘Sparrow’ derives from Anglo-Saxon ‘Spearwa’, which means ‘flutterer’, and it has been applied to many small birds (Choate). ‘Lark’ was given to this bird likely because of its song. Latin genus name ‘Chondestes’ would mean ‘seed eater’. Latin species name ‘grammacus’ would mean ‘streaked’.
HABITAT: Open areas such as fields, prairies, often with bare ground.
DIET: Insects and seeds.
NESTING: Nest is built on the ground or in a shrub. Sometimes this sparrow will use another species nest. Around three to five whitish eggs are laid, incubated by female. Chicks fed by both parents.
DISTRIBUTION: Breeds in south central Canada and western half of USA. Winters in Mexico. Year-round resident in Texas, northern Mexico and coastal part of south California.

ON PEI: Does not breed on Prince Edward Island, sightings listed as ‘accidental’ so far. See note below on bird vagrancy.
CONSERVATION: Numbers healthy in most of its range. However in British Columbia it is on the Red List due to loss of habitat and prey (due to use of pesticides).
NOTES: This sparrow is a ‘walker’ rather than a ‘hopper’.
Vagrancy: In biology this means an animal going way outside its normal range. For birds, this can happen when there are storms and they get blown off course. On other times, the bird simply wanders in a different direction than usual. Here’s an article about vagrancy in birds.
