Spring habitat selection by the Mediterranean Horseshoe Bat (Rhinolophus euryale) in the Urdaibai Biosphere Reserve (Basque Country)

Spring habitat selection by the Mediterranean Horseshoe Bat (Rhinolophus euryale) in the Urdaibai... INTRODUCTION Rhinolophus euryale is one of the most endangered bat species in Europe (Stebbings 1988 ; Council of the European Communities 1992; Ibanez 1999 ; Hutson et al 2001 ; Urcun 2002). Some authors have reported a strong population decline, for example in Slovakia, France or the Basque Country (Rybar 1981 in Stebbings and Griffith 1986 ; Brosset et al 1988 ; Aihartza 2001). Disturbance and loss of roost places, uncontrolled ringing, intensive use of organochlorine insecticides, and transformation of natural habitats have been stressed as the most important causes of decline (Benzal et al 1988 ; Brosset etal 1988 ; Makin 1989 ; Palmeirim and Rodrigues 1992). Little is known about its ecology and only few works dealt with its roosting requirements (Brosset and Caubere 1959 ; Dulic 1963), activity pattern (Masson 1990) or roosting behaviour (Masson 1999). Recent diet analyses show that R. euryale feed predominantly on Lepidoptera, Diptera (mainly Tipulidae) and Neuroptera (Koselj and Krystufek 1999 ; but see Grabovac et al. 1999). Brosset et al.
