Sierra Madre Sparrow

The perching bird

Published measurements include mass about 17.

Range and habitat

The species is endemic to some mountain ranges in and near the Sierra Madre Occidental, Mexico. It is restricted to bunchgrass and marshland habitat (zacatonal) in volcanic mountain ranges, at elevations of 2,300–3,050 metres (7,550–10,010 ft). The lower part of the range is occupied by the northern, and the higher part by the southern population. Habitat information for the northern population is scant, with pine, oak, and Arbutus (probably Arizona Madrone, A. Arizonica) trees being mentioned.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Habits

Perching birds hold with three toes forward and one back. A named island starling or leafbird in this catalog is a wild population, not a cage type.

In crisis

The Sierra Madre sparrow, also known as Bailey's sparrow, is an endangered, range-restricted, enigmatic American sparrow. It is endemic to Mexico and is threatened with extinction through habitat loss. It is highly threatened due to clearance of its habitat for creating pastures.

Its conservation status on the IUCN Red List is Endangered. This is because the species occurs in less than 5000 km², and its range, available habitat, and population size are shrinking (BirdLife International 2004).

Sierra Madre Sparrow is Endangered on this catalog because that is the IUCN category stored on Wikidata. Confirm the official criteria and any later count on iucnredlist.org.
