Demography and Populations


Populations appear to be relatively large (66), and the species is reported to be locally common to fairly common (4). There are no long-term survey data, but the population is believed to be in small decline (66).

Disease and Body Parasites

In Nevado de Toluca and Valle de Bravo, Mexico (67) (n = 6):

  • 1 individual infected with Haemoproteus spp. with a "medium intensity infection."
  • 1 individual infected with Leucocytozoon spp. with a "medium intensity infection."

Causes of Mortality

No information.

Population Spatial Metrics

Individual Distance

No information.

Territory Size

Marshall (52: 118) suggested that the species "did not seem to have territorial boundaries." See Home Range Size.

Home Range Size

May be loosely colonial (4). Marshall (52: 118) suggested that home ranges overlapped and described a meadow, ~1.2 km in diameter, as occupied by a "colony" of 24 adults.

Population Status


There are no estimates of population size based on survey data, but populations are reported to be relatively large (66). Reported to be locally common to fairly common (4).

During 25–26 June 1952 in Upper Rio Gavilan, Chihuahua, Marshall (52) reported a density of "4.8 pairs of Striped Sparrow per km in the sampled habitat" (a meadow of 1-km diameter with a colony of about 24 adults). During spring and summer 2016 in Playa Cebolletas, a small montane grassland in Aguascalientes, 7 individuals were recorded in 4.9 ha (~140 individuals per km2) (DACM).


There are no long-term survey data, but the population is believed to be in small decline (66).

Population Regulation

No information.
