VespertilionidaeConservation

RANGE DESCRIPTION:

To the Philippines, it has been recorded from the islands of Biliran, Leyte, Luzon (Camarines Sur Province), Mindanao (Bukidnon Province), Palawan, and Samar (Taylor 1934; Heaney et al. 1998). Over its range, it has been recorded between 60 and 2,100 m asl.

HABITAT:

On Palawan Island, there are records from a bamboo thicket at 60 m and primary lowland forest at 650 m (Esselstyn et al. 2004).

MAJOR THREATS:

There appear to be no major threats to this somewhat adaptable species.

RANGE DESCRIPTION:

In the Philippines, there are records from Jolo (Taylor 1934), Mindanao (Davao del Norte Province) and Palawan (Heaney et al. 1998).

HABITAT:

There are records of two groups roosting in dead leaves on small shrubs in lowland forest in the Philippines (Taylor 1934; Heaney et al. 1998). On Palawan Island, there are records from secondary lowland forest at 80 m asl (Esselstyn et al. 2004).

MAJOR THREAT:

This species is dependent on primary forest which is being lost due to logging, plantations, conversion to agriculture and forest fires.

Least Concern

Whitehead’s Woolly Batfound in Brunei, Indonesia,Malaysia, the

Philippines, and Thailand.forearms, 30-31 mm.

Page 7: Bats of the Phillipines: Family Vespertilionidae

RANGE DESCRIPTION:

In the Philippines, records are from Luzon Mindanao (Davao del Norte, Davao del Sur, Davao Oriental, and Zamboanga del Norte Provinces), Palawan, and Panay (Heaney et al. 1998; Taylor 1934) and Polillo (Alviola 1999).

HABITAT:

In the Philippines, the species has been found in disturbed forest and agricultural areas (Sanborn 1952). On Palawan island, it has been reported from cogon grassland at around 60 m asl (Esselstyn et al. 2004) and in secondary forest beside a creek at 450 m asl on Mt. Makiling (Laguna, Luzon) (Heaney et al. 1998; Sedlock 2001).

MAJOR THREAT:

There are no major threats to this species throughout its range. In the Philippines, the species is locally threatened at higher elevations in montane forest on ultramafic soils through activities associated with mining (D. Balete pers. comm. 2006).

RANGE DESCRIPTION:

 It occurs throughout the Philippines except Babuyan/Batanes group with specimens recorded from Bongao, Bohol, Capiz, Catanduanes, Guimaras, Leyte, Luzon (Bulacan, Kalinga (Heaney et al. 2004), and Rizal provinces), Mindanao (Davao del Norte, Davao del Sur, Maguindanao, and Zamboanga del Norte provinces), Negros, Panay, Polillo, and Siquijor (Heaney et al. 1998) being found from sea level to about 925 m asl (Heaney et al. 1998; Esselstyn et al. 2004; Heaney et al. 2004). The species has also been recorded from Samar (J. C. Gonzales pers. comm. 2006), Cebu (Paguntalan pers. comm. 2006) and on Isarog at 1,450 m asl (Sedlock unpubl. data).

HABITAT:

In the Philippines, the species is often dependent on caves (Heaney et al. 1998, Esselstyn et al. 2004) where it forages over the canopy in secondary and primary lowland areas, including agricultural areas (Heaney et al. 1991; Lepiten 1995; Rickart et al. 1993; Sanborn 1952; Taylor 1934). It has also been documented in montane forest on Luzon (Heaney et al. 2004).

MAJOR THREAT:

There are no major threats to this species, although it is presumably locally threatened by disturbance of maternity caves. In the Philippines, limestone quarrying is destroying roosting habitat and it is also threatened by disturbance caused by guano mining there, however, individuals reoccupy caves once the disturbance ceases.

forearms, 42-46 mm.average size for a vesper bat.slightly bigger than the Miniopterus australis.

RANGE DESCRIPTION:

Occurs from south-western Europe and north and west Africa through Anatolia and the Middle East to the Caucasus. In Africa it is known from records in North Africa (Morocco, Algeria, Tunisia, Libya), and west Africa (Guinea, Sierra Leone, Liberia, Nigeria, Cameroon). It is patchily distributed over its range in some huge and vulnerable colonies.

HABITAT:

It forages in a variety of open and semi-open natural and artificial habitats, including suburban areas. It feeds mainly on moths, and occasionally on flies. It is a colonial species that roosts mostly in caves and mines (although it can also be found in man made tunnels, ruins and other buildings), often in large mixed colonies with other cave-dwelling bat species.

MAJOR THREAT:

The disturbance and loss of underground habitats and pesticide use may threaten this species. In the Caucasus, disturbance caused by tourism in caves is a problem (K. Tsytsulina pers. comm. 2005).

RANGE DESCRIPTION:

It is found throughout the Philippines with records from Bohol, Cebu, Guimaras, Leyte, Lubang, Luzon, Palawan, Mindanao (Maguindanao, and Zamboanga del Norte provinces), Mindoro, Negros, Samar, and Tablas (Hollister 1912; Lawrence 1939; Peterson 1981; Taylor 1934; Heaney et al. 1998; Esselstyn et al. 2004) where it occurs from sea level up to 430 m asl (Heaney et al. 1998; Esselstyn et al. 2004). It has been recorded between sea level and 1,600 m over its entire range.

HABITAT:

On Palawan it has been recorded in old growth forest (Esselstyn et al. 2004). It is an aerial insectivore that catches insects above the forest canopy, in open areas, in disturbed forest and in some agricultural areas.

MAJOR THREAT:

There are no major threats to this species throughout its range, however, locally it is affected by disturbance of caves.

HABITAT:

In the Philippines, this species is found in primary lowland forest, lightly disturbed lowland and lower montane forest (Heaney et al. 1991; Lepiten 1995, Rickart et al. 1991, Ruedas et al. 1994). It has also been recorded from secondary forest elsewhere (G. Csorba pers. comm. 2006).

MAJOR THREAT:

The threats to this species are not well known, although it is unlikely to be threatened throughout its range.

RANGE DESCRIPTION:

In the Philippines, it has been recorded from sea level to 800 m asl (Heaney et al. 1998) although there is a record from 1,450 m asl on mount Isarog Camarines Sur Province, in the southeastern portion of Luzon Island.

HABITAT:

In the Philippines, it has been recorded near to streams in lowland forest, disturbed forest and agricultural areas. In the Philippines, it sometimes roosts in caves and in tunnels and has been reported roosting beneath a large rock over a stream (Taylor, 1934).

MAJOR THREAT:

There appear to be no major threats to this species as a whole.
