According to the locals who work on the caye, the bats are thought to roost in the coconut trees during the day. ''Rhogeessa'' spp. on the keys and southern BZE are likely ''R. tumida'', not ''R. aeneus''. Surveys on the Yucatan Peninsula in BZE (Ambergris Key) suggest ''R. tumida'' is the local species.

Yucatán Peninsula
The Yucatán Peninsula (, also , ; es, Península de Yucatán ) is a large peninsula in southeastern Mexico and adjacent portions of Belize and Guatemala. The peninsula extends towards the northeast, separating the Gulf of Mexico to the north and west of the peninsula from the Caribbean Sea to the east. The Yucatán Channel, between the northeastern corner of the peninsula and Cuba, connects the two bodies of water. The peninsula is approximately in area. It has low relief, and is almost entirely composed of porous limestone. The peninsula lies east of the Isthmus of Tehuantepec, the narrowest point in Mexico separating the Atlantic Ocean, including the Gulf of Mexico and Caribbean Sea, from the Pacific Ocean. Some consider the isthmus to be the geographic boundary between Central America and the rest of North America, placing the peninsula in Central America. Politically all of Mexico, including the Yucatán, is generally considered part of North America, while Guatemala an ...

Belize
Belize (; bzj, Bileez) is a Caribbean and Central American country on the northeastern coast of Central America. It is bordered by Mexico to the north, the Caribbean Sea to the east, and Guatemala to the west and south. It also shares a water boundary with Honduras to the southeast. It has an area of and a population of 441,471 (2022). Its mainland is about long and wide. It is the least populated and population density, least densely populated country in Central America. Its population growth rate of 1.87% per year (2018 estimate) is the second-highest in the region and one of the List of countries by population growth rate, highest in the Western Hemisphere. Its Capital city, capital is Belmopan, and its largest city is the namesake city of Belize City. Belize is often thought of as a Caribbean country in Central America because it has a history similar to that of English-speaking Caribbean nations. Indeed, Belize’s institutions and official language reflect its histor ...

Guatemala
Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America. It is bordered to the north and west by Mexico; to the northeast by Belize and the Caribbean; to the east by Honduras; to the southeast by El Salvador and to the south by the Pacific Ocean. With an estimated population of around million, Guatemala is the most populous country in Central America and the 11th most populous country in the Americas. It is a representative democracy with its capital and largest city being Nueva Guatemala de la Asunción, also known as Guatemala City, the most populous city in Central America. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica. In the 16th century, most of this area was conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence in 1821 from Spain and Mexico. In 1823, it became part of the Fe ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering t ...

Black-winged Little Yellow Bat
The black-winged little yellow bat (''Rhogeessa tumida'') is a species of Vespertilionidae, vesper bat native to Central America. Description The black-winged little yellow bat is a small bat, with a total length of between , and no significant difference in size between the sexes. The fur is buff or yellowish, ticked with near-black or cinnamon, and is paler on the bat's underside. The flight membranes are hairless, and unusually thick for a bat of its size. The ears are smaller than in many closely related species, and have a prominent scent gland on their upper surface in males that is absent in females. Biology Little is known of the habits of biology of the species. Individuals have commonly been caught near streams or rivers, and roost in hollow trees or artificial structures. They are nocturnal, being most active shortly after sunset and just before dawn, and feed on small, flying insects. They have diploid chromosome numbers of 30, 32, 34, and 52. Males produce the most s ...

Caye
A cay ( ), also spelled caye or key, is a small, low-elevation, sandy island on the surface of a coral reef. Cays occur in tropical environments throughout the Pacific, Atlantic, and Indian Oceans, including in the Caribbean and on the Great Barrier Reef and Belize Barrier Reef. Etymology The 1492 indigenous people of the Bahamas were called " Lucayan", an Anglicization of the Spanish ''Lucayos'', derived in turn from the Taíno ''Lukku-Cairi'' (which the people used for themselves), meaning "people of the islands". The Taíno word for "island", ''cairi'', became ''cayo'' in Spanish and "cay" in English (spelled "key" in American English, "caye" in Belizean English). Formation and composition A cay forms when ocean currents transport loose sediment across the surface of a reef to where the current slows or converges with another current, releasing its sediment load. Gradually, layers of deposited sediment build up on the reef surface – a '' depositional node''. Such n ...

Rhogeessa
''Rhogeessa'' is a genus of bats within the vesper bats family, Vespertilionidae. Species *Yucatan yellow bat (''R. aeneus'') *Allen's yellow bat (''R. alleni'') * Bickham's little yellow bat (''Rhogeessa bickhami'') * Genoways's yellow bat (''R. genowaysi'') *Slender yellow bat (''R. gracilis'') *Husson's yellow bat (''R. hussoni'') * Thomas's yellow bat (''R. io'') * Menchu's little yellow bat (''R. menchuae'') * Tiny yellow bat (''R. minutilla'') *Least yellow bat (''R. mira'') * Little yellow bat (''R. parvula'') *Black-winged little yellow bat (''R. tumida'') * Ecuadorian little yellow bat (''R. velilla'') Taxonomy debate This genus is systematically complex and sometimes controversial. One reason that the genus is complex is because of the species' variable karyotypes:Baird, A. B., Hillis, D. M., Patton, J. C., & Bickham, J. W.

Bats Of Central America
Bats are mammals of the order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochiro ...
