description: 155. Davis’s Tent-making Bat <i>Uroderma davisi</i> <b>French:</b> Uroderme de Davis / <b>German:</b> Davis-Zeltfledermaus / <b>Spanish:</b> Urodermo de Davis <b>Taxonomy.</b> Uroderma bilobatum davis R. J. Baker &amp; McDaniel, 1972, “ 3 mi. [= 4-8 km] NW La Herradura, La Paz, El Salvador, elevation about 20 meters.” Uroderma davisi was diagnosed by its karyotypic distinction from U. bilobatum, as well as being slightly smaller. Monotypic. <b>Distribution.</b> Known from Pacific side of Central America from E Oaxaca, Mexico, S to El Salvador; possibly also in adjacent Honduras. <b>Descriptive notes.</b> Head—body 57-66 mm (tailless), ear 12-17, hindfoot 9-12, forearm 40-43 mm; weight 13-16 g. Dorsal fur of Davis’s Tent-making Bat is dark gray to graybrown; hairs are bicolored, with pale bases and brownish tips. White, narrow, median dorsal stripe extends from back of head or neck to rump. Conspicuous white facial stripes occur above and below eyes, with entirely white hairs. Supraocularstripes extend over head to back of ears. Ears and noseleaf are blackish brown, prominently edged with white/yellow margins. Tragus is usually tinged with yellow for almost one-half its length. Muzzle is relatively long and broad, and forehead is almost indistinguishable. Uropatagium is well developed (13-15 mm) and relatively naked, with notch near level of knees. Calcaris smaller than foot. Proximal one-half of forearm is hairy. Skull has relatively long rostrum, slightly concave in profile view. Palate is relatively broad, long, and U-shaped posteriorly. I' are bilobed and parallel to each other. Small gap occurs between P° and P*. Chromosomal complement has 2n = 44 and FN = 48. <b>Habitat.</b> Tropical forests of Pacific slope of Central America, including moist evergreen forests, deciduous lowland forests, dry tropical forests, fruit groves, and stretches of riparian forests along streams, from sea level to elevations of ¢. 1000 m (most common below 600 m). Davis's Tent-making Bat is present in human-disturbed areas, mostly close to banana plantations. <b>Food and Feeding.</b> Diet of Davis's Tent-making Bat consists mainly offruits, including Cecropia (Urticaceae), Ficus (Moraceae), and Solanum (Solanaceae). When foraging, it carries fruits (some as large as 6: 6 g or 30% of its body weight) to feeding roosts or consumes them on the fruiting tree. It is commonly netted on edges of fruit and banana plantations. <b>Breeding.</b> Davis's Tent-Making Bat has a polygynous mating system. Peaks in numbers of pregnant and lactating females were recorded in July-September in south-western Guatemala. One young is born per pregnancy. <b>Activity patterns.</b> Davis’s Tent-making Bat is an understory frugivore and forages in cluttered and open spaces.It roosts exclusively in foliage. Day roosts include unmodified foliage and leaves modified into tents. Tents are made from leaves of bananas, pinnate palms, and palmate palms. <b>Movements, Home range and Social organization.</b> Palm leaf tents frequently had 1-7 individuals (harems), but nursing females were usually found alone or with juveniles. Davis’s Tent-making Bats can be locally abundant where availabilities of food and roost sites are high. Broad contact zone between two chromosomal races—now Davis's Tent-Making Bat to the north and the Pacific Tent-making Bat (U. convexum) to the south— occurs in the Pacific lowlands of north-western Nicaragua, south-western Honduras, and southern El Salvador. <b>Status and Conservation.</b> Not assessed on The IUCN Red List. Davis's Tent-making Bat was previously considered part of the Common Tent-making Bat (U. bilobatum), which is classified as Least Concern. A proper assessment of the recently recognized Davis’s Tent-making Bat is required to fully understand its conservation status. <b>Bibliography.</b> Baker &amp; Clark (1987), Baker &amp; McDaniel (1972), Baker et al.
