In some phyllostomids visual acuity and sensitivity are remarkably well developed (Manske and Schmidt, 1976; Bell and Fenton, 1986); these bats are even capable of distinguishing simple visual patterns (Manske and Schmidt, 1979; Suthers et al., 1969). Thus, it is not surprising that in many orientation situations vision is involved. E.g., bats searching for an exit attend to light and disregard echolocation (Chase, 1983); obstacle avoidance as well is aided by vision (Chase and Suthers, 1969; Rother and Schmidt, 1982). Macrotus californicus uses vision to find prey on the ground (Bell, 1985).
