Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-08-08
Assessor(s): Miller, B. & Rodriguez, B.
Reviewer(s): Solari, S.
This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species can be found in coniferous and broadleaf forest and dry thorn scrub (Reid 2009). It roosts in Spanish moss, under dead palm leaves or dry corn stalks. This species appears to be more social than other Lasiurus species, and may form nursery colonies. It usually forages 3 to 4 m above ground over open, grassy areas, and 100 or more bats may aggregate when feeding (Barbour and Davis 1969). Northern populations reproduce in May to June, and litter size is 2 to 4 (Reid 2009). Northern yellow bats rarely roost in buildings or other human-made structures. Foraging habitat is primarily open areas such as fields, pastures, airports, golf courses, marshes, lake borders, and the open savanna-like habitat of sandhills, also forest edges and spaces above trees.

Threats [top]

Major Threat(s): No major threats are known. Locally, populations may be negatively affected by reduction of available roosting habitat. Relatively low numbers of this species have been found dead near turbines at wind energy facilities.

Conservation Actions [top]

Conservation Actions: It is found in some protected areas. Research actions are needed as many aspects of its biology are unknown.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
