Distribution

Range Description

It is mainly a Palaearctic species, although the south-eastern edge of its range extends into the Indomalayan region. It is well known in the Mediterranean basin, occuring from Portugal, Spain eastwards through southern Europe to the Balkans, Turkey, Israel, Palestine and Jordan. In North Africa it has been recorded from Morocco, Algeria, Tunisa, Libya and Egypt. It is possibly present on Madeira (to Portugal) as there was a supposed old record, but it has not been recorded from there again. It occurs on all the Canary Islands (to Spain) except for Fuerteventura and Lanzarote. It is also recorded from a number of Mediterranean islands (Hutson 1999, Simmons 2005).

Populations in Japan, Taiwan and Korea are now considered to be a separate species, T. insignis (Simmons 2005). It occurs from sea level to 3,100 m.

Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
It usually forages at 10 to 50 m above the ground over temperate to semi-desert habitats, although it also occurs in humid habitats in some areas (e.g., Turkey: A. Altiparmak pers. comm. 2005). It feeds on aerial drifts of insects including moths and neuropterans. Summer and winter roosts: fissures and hollows in rock outcrops, quarries and cliffs. Common in some urban areas, roosts also in artificial structures including bridges and buildings. In North Africa it prefers rocky habitats and is not found in caves. The species is probably sedentary in Europe (Hutterer et al. 2005), although it may be a partial migrant in North Africa (GMA Africa Workshop 2004).

Habitat

This species favours open habitats, such as grasslands and shrublands, from sea level up to 2,300 metres. It roosts in fissures and hollows in rocky outcrops, quarries and sea cliffs. It is fairly common in some urban areas and sometimes roosts in artificial structures such as bridges, water towers, cathedrals and other tall buildings.

Life History and Behavior

Behavior

Behaviour

A nocturnal species, the European free-tailed bat emerges from its roost at night to feed primarily on flying insects, such as moths. Flying high and fast, it uses low frequency echolocation calls to detect its prey. The heavily-built European free-tailed bat is capable of reaching speeds of over 50 km/h and possesses the stamina to hunt for food for up to ten hours without a resting period. It is not clear whether this species, like many other bats, hibernates during winter.

The European free-tailed bat is typically found roosting in colonies containing between 5 and 50 individuals; although colonies of up to 400 individuals have also been recorded. Female European free-tailed bats typically give birth to a single young each year, in the summer months. It is thought to have a life span of over ten years.

Reviewer/s
Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Temple, H. (Global Mammal Assessment Team)

Justification
The species is widely distributed over a large extent of occurrence. let occurs in urban areas and forages in other modified habitats. Population trends are not known, but are not believed to approach the threshold for the population decline criterion of the IUCN Red List. Consequently it is assessed as Least Concern.

Population

Population
It is a common species in suitable habitats. Summer and winter colonies typically number 5-100 individuals, although colonies of up to 300-400 animals have been recorded. It is probably sedentary, although seasonal in some areas (e.g., Malta). It is not abundant in the Caucasus, nor is it highly gregarious - large colonies are not known in this region (K. Tsytsulina pers. comm. 2005) There are only six records for Iran, however, there have not been extensive survey efforts there (M. Sharifi pers. comm. 2005).

Threats

Threats

Major Threats
It is negatively affected by disturbance and loss of roosts in buildings, and by use of pesticides. It is also potentially threatened by wind farms (GMA Europe Workshop 2006), and deforestation affects the species in some parts of its range (Z. Amr pers. comm. 2005). However, none of these are considered to be major threats at present.

European Free-tailed Bat

The European Free-tailed Bat. (Tadarida teniotis, sometimes given as Tadarida insignis) is a species of free-tailed bat found across the Old World. An adult European Free-tailed Bat has a body length of 8.4-9.4 cm, a tail of 4.8-5.6 cm, and a wing length of 5.7-6.5 cm. This species had been reported from Korea in 1931, but has not been sighted on the Korean Peninsula since that time.
