Big free-tailed bat

The big free-tailed bat ("Nyctinomops macrotis") is a bat species found in South, North and Central America, as well as the Caribbean.
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.
Description.
It is the largest member of "Nyctinomops", with an average forearm length of .
Individuals weigh approximately .
It has a wingspan of .
Its fur is glossy and variable in color, ranging from pale, reddish brown to dark brown or blackish.
Its dental formula is for a total of 30 teeth.
Biology and ecology.
Based on its wing morphology, it likely has a rapid flight.
Its flight speed could exceed .
Range and habitat.
Its range includes many countries in North, Central, and South America.
Specific countries that it inhabits include: 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.
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.
It has been documented at a range of elevations from sea level to above sea level.
Conservation.
As of 2015, it is evaluated as a least-concern species by the IUCN, which is its lowest conservation priority.
It meets the criteria for this assessment because it has a large geographic range; it is unlikely to be experiencing rapid population decline; and its population is presumably large.
