The big free-tailed bat (Nyctinomops macrotis) is a bat species found in the Americas.
Taxonomy
It was described as a new species in 1839 by British zoologist John Edward Gray. Gray placed it in the now-defunct genus Nyctinomus, with a binomial of Nyctinomus macrotis. The holotype had been collected in Cuba by William Sharp Macleay.[2]
Description
It is the largest member of Nyctinomops,[3] with an average forearm length of 60 mm (2.4 in).[4] Individuals weigh approximately 20.6 g (0.73 oz). It has a wingspan of 417–436 mm (16.4–17.2 in). Its fur is glossy and variable in color, ranging from pale, reddish brown to dark brown or blackish.[4] Its dental formula is 1.1.2.32.1.2.3 for a total of 30 teeth.[3]
Biology and ecology
Based on its wing morphology, it likely has a rapid flight. Its flight speed could exceed 40 km/h (25 mph).[4]
Range and habitat
Its range includes many countries in North, Central, and South America, including: Argentina , Brazil , Canada , Colombia, Cuba, the Dominican Republic, Ecuador, French Guiana, Guyana, Haiti, Jamaica, Mexico, Suriname, the United States , and Venezuela. It is possibly also found in Uruguay.[1] The individuals documented in Canada and the U.S. states of Iowa and Kansas are considered vagrants or extralimital records. However, the species occurs as a non-vagrant in the U.S. states of Texas , California , Nevada, and Utah.[4] It has been documented at a range of elevations from sea level to 2,600 m (8,500 ft) above sea level.[1]
Conservation
As of 2015, it is evaluated as a least-concern species by the IUCN, which is its lowest conservation priority.[1]
