Schlieffen's serotine (Nycticeinops schlieffeni), also known as Schlieffen's bat or Schlieffen's twilight bat, is a species of vesper bat found in Africa. It has been placed in numerous genera since its first description in 1859, but morphological and genetic studies have confirmed it as the only species in the genus Nycticeinops. [2] [3] It is named for the collector of the original specimen, Wilhelm von Schlieffen-Schlieffiennburg. [4]

Description

Schlieffen's serotine is an unusually small bat, measuring 4 to 5 centimetres (1.6 to 2.0 in) in head-body length, and weighing only 3.7 to 5 grams (0.13 to 0.18 oz). Although there is some variation on coat colour across its range, in general, the bat is brown with pale grey or white underparts. It has a broad, flattened skull, with a short, wide, sparsely haired snout. The ears are rounded, with a blunt, convex, tragus. There is a prominent calcar extending about half the way along the uropatagial border, and a proportionately long tail of approximately 3 centimetres (1.2 in). [4]

In many respects, Schlieffen's serotines resemble the more familiar evening bats of North America; they can most readily be distinguished by the shorter snout, and by the detailed shape of the baculum. [4]

Distribution and subspecies

Schlieffen's serotine is found widely across Africa outside the equatorial rainforest. It inhabits a broad band of territory from Mauritania and Senegal in the west across to Namibia, South Africa, Angola and Mozambique in Southern Africa, to Kenya and Tanzania in the African Great Lakes region, to Ethiopia, Somalia, Djibouti and Eritrea in the Horn of Africa, to Sudan and Egypt in the Nile Valley. It is also found in the south-western Arabian peninsula. [4]

Several subspecies of Schlieffen's serotine have been identified. However, there has been little agreement on their status or range. The most recent analysis, as reported in the 2005 edition of Mammal Species of the World , concluded that there is insufficient evidence for the retention of any of these subspecies, and Schlieffen's bat should therefore be considered monotypic. [5]

Behaviour and biology

Schlieffen's serotines forage over fresh water, such as marshes, rivers, and lakes, and are found in a wide range of riparian forest and savannah environments. Like many bats, they are nocturnal, and they spend the day roosting in crevices in rocks and trees, and may take up residence in man-made buildings or cellars. They appear to be generally solitary, but may roost in small groups of three or so individuals. [4]

The echolocation calls of Schlieffen's serotines have been reported to be narrow band with steep frequency modulation, and to range from 39 to 47 kHz. They feed primarily on beetles and caddisflies, and a smaller proportion of moths, bugs, and flies. [6] Their predators are known to include bat hawks. [7]

Schlieffen's bats mate in June, but carry the sperm in their uterus until August, when ovulation and fertilisation occur. [8] They typically give birth to a litter of three young. [9]

Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus Vespertilio, which takes its name from a word for bat, vespertilio, derived from the Latin term vesper meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds".

Compared to other microbats, the big brown bat is relatively large, weighing 15–26 g (0.53–0.92 oz) and possessing a wingspan of 32.5–35 cm (12.8–13.8 in).

The common vampire bat is a small, leaf-nosed bat native to the Neotropics. It is one of three extant species of vampire bat, the other two being the hairy-legged and the white-winged vampire bats. The common vampire bat practices hematophagy, mainly feeding on the blood of livestock. The bat usually approaches its prey at night while they are sleeping. It then uses its razor-sharp teeth to cut open the skin of its hosts and lap up their blood with its long tongue.

After the first specimen was caught in 1967, it was described as a subspecies of Eptesicus somalicus in 1995. After four more specimens were collected in 2002 and 2003, it was recognized as a separate species. Because of its small distribution and the threat of habitat destruction, it is considered "vulnerable" in the IUCN Red List.

A maternity colony refers to a temporary association of reproductive female bats for giving birth to, nursing, and weaning their pups. The colonies are initiated by pregnant bats. After giving birth, the colony consists of the lactating females and their offspring. After weaning, juveniles will leave the maternity colony, and the colony itself will break apart. The size of a maternity colony is highly variable by species, with some species forming colonies consisting of ten or fewer individuals, while the largest maternity colony in the world in Bracken Cave is estimated to have over 15 million bats.
