Endangered
Greater long-nosed bat
Leptonycteris nivalis
Greater long-nosed bat is a bat in the family Phyllostomidae (order Chiroptera) — Leptonycteris nivalis, recorded as Endangered.
Appearance
Individual hairs are white at the base, and silver at the tips.
Their forearms are 54–59 mm (2.1–2.3 in) long.
Range and habitat
The species is found in southern Texas, Arizona, and New Mexico from June through August. It is found in central Mexico throughout the rest of the year. While it has been alleged that the bats are found as far south as Guatemala, the IUCN disputes this notion, and lists its southernmost occurrence as central Guerrero.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Because male testes are significantly larger during the mating season and females mate with multiple males, there is likely sperm competition between males. It is thought that they are monoestrous. Therefore they only breed once per year.
Birth likely occurs during May, during female migration to northern Mexico or the southwestern United States. Males are likely non-migratory, and adult males are rarely encountered in the United States.
In crisis
Its habitat includes desert scrub and open woodlands, even so, it is threatened by habitat loss. Population numbers of this species have likely been in decline for several decades. In 1988, the United States Fish and Wildlife Service listed it as endangered.
The species is listed as threatened in Mexico. There is evidence that the population in the United States has increased since 1984, with the population in Arizona one hundred times greater in 2000 than it was in 1984.
