The Cape horseshoe bat (Rhinolophus capensis) is a species of bat in the family Rhinolophidae. It is endemic to South Africa, and is potentially threatened by habitat loss and disturbance of its roosting sites, although it is present in large enough numbers to be considered of least concern by the IUCN. [1]

Contents

It is a member of the Rhinolophus capensis species group, together with the Bushveld, Dent's and Swinny's horseshoe bats, and is monotypic, with no subspecies. [2]

Description

The Cape horseshoe bat is a typically sized member of its family, with a head-body length of 5.8 to 6.2 centimetres (2.3 to 2.4 in) and a tail 2.4 to 3.2 centimetres (0.94 to 1.26 in) long. They weigh between 10 and 16 grams (0.35 and 0.56 oz). The fur is dark or pale brown over most of the body, with paler, fawn-grey, underparts. The ears are large and somewhat rounded, and are capable of independent movement. The nose-leaf is horseshoe-shaped, and does not reach the upper parts of the muzzle. A rounded, sparsely-haired, process runs from the upper mid-surface of the nose-leaf to a projecting spear-shaped lancet above and between the eyes. [2]

The wings have a low wing loading and a high aspect ratio, indicating that the bat is capable of only slow flight, but is highly manoeuvrable in the air. This allows it to forage effectively among dense vegetation. [2] [3]

Biology

Cape horseshoe bats are endemic to Cape Province in South Africa, where they inhabit shrubby coastal environments. They are nocturnal, spending the day roosting in large colonies in coastal caves or mine adits. They are often found together with other species of bat, including Geoffroy's horseshoe bat and Schreibers' long-fingered bat. They are ambush hunters, hiding among vegetation and preying mainly on beetles and moths. Their echolocation calls are relatively long, lasting from 28 to 42 milliseconds, with only short pauses between pulses. The peak frequency varies between different individuals, ranging from 82 to 86 kHz. This type of call enables them to quickly locate rapidly moving insects in cluttered environments with plentiful vegetation. [2]

The breeding season lasts from August to September, shortly after the bats awake from winter hibernation. However, spermatogenesis in the males occurs between October and May, with the sperm being stored in the epididymis until the start of the breeding season. [4] Gestation lasts three or four months, so that the mother gives birth to a single young in November or December, shortly before the rainy season, when insects are at their most abundant. [5] The young are weaned by the end of January, and reach sexual maturity in their second year. [4]

Horseshoe bats are bats in the family Rhinolophidae. In addition to the single living genus, Rhinolophus, which has about 106 species, the extinct genus Palaeonycteris has been recognized. Horseshoe bats are closely related to the Old World leaf-nosed bats, family Hipposideridae, which have sometimes been included in Rhinolophidae. The horseshoe bats are divided into six subgenera and many species groups. The most recent common ancestor of all horseshoe bats lived 34–40 million years ago, though it is unclear where the geographic roots of the family are, and attempts to determine its biogeography have been indecisive. Their taxonomy is complex, as genetic evidence shows the likely existence of many cryptic species, as well as species recognized as distinct that may have little genetic divergence from previously recognized taxa. They are found in the Old World, mostly in tropical or subtropical areas, including Africa, Asia, Europe, and Oceania.

<span class="mw-page-title-main">Greater horseshoe bat</span> Species of bat

The greater horseshoe bat is an insectivorous bat of the genus Rhinolophus. Its distribution covers Europe, Northern Africa, Central Asia and Eastern Asia. It is the largest of the horseshoe bats in Europe and is thus easily distinguished from other species. The species is sedentary, typically travelling up to 30 kilometres (19 mi) between the winter and summer roosts, with the longest recorded movement being 180 km (110 mi). The frequencies used by this bat species for echolocation lie between 69–83 kHz, have most energy at 81 kHz and have an average duration of 37.4 ms.
