TL;DR: Small groups of the tent-making bat, Ectophylla alba, were found roosting in Heliconia (Musaceae) tents in old secondary-growth forest in north-eastern Costa Rica, where tents were used either as night feeding roosts or as day-roosts for as long as 45 days.
Abstract: Small groups of the tent-making bat, Ectophylla alba, were found roosting in Heliconia (Musaceae) tents in old secondary-growth forest in north-eastern Costa Rica. The choice of specific Heliconia leaves for tents was predicted on the basis of leaf size and age. Additionally, tents in shrubs, saplings and epiphytic plants were found scattered throughout both primary- and secondary-growth forest. Tents were used either as night feeding roosts or as day-roosts for as long as 45 days. Groups of bats remained together when they moved to newly cut tents. After parturition, tent groups divided into all-male colonies and maternity colonies with females, non-volant young and a single adult male.
TL;DR: The Honduran white bat was found to alter the leaves of five species of Heliconia for use as diurnal roosts, and an hypothesis of leaf size selection, tent utilization, and evolution of tent construction is presented.
Abstract: Ectophylla alba H. Allen (Chiroptera: Phyllostomatidae), the Honduran white bat, was found to alter the leaves of five species of Heliconia (H. imbricate, H. latispatha, H. pogonantlia, H. tortuosa, and an undescribed species) for use as diurnal roosts. By cutting the side veins extending out from the midrib, the bats cause the two sides of the leaf to fold down around the midrib forming a tent. More tents were found on H. imbricate and H. tortuosa than on the other three species, but these were the most abundant species at the Costa Rican locality. The bats appeared to be selecting a specific size-class of leaves for tent construction rather than leaves of a particular species of Heliconia. Honduran white bats were found roosting in groups of 1-6 individuals. It appeared that a colony of bats roosts in a number of tents scattered within the forest. An hypothesis of leaf size selection, tent utilization, and evolution of tent construction is presented.
TL;DR: Investigating tent construction is presented for the first time information on tent construction by a phyllostomid bat in the field, and a female Ectophylla modifying Heliconia leaves into a tent is observed, the first direct Tent building by female ECTophylla alba in Costa Rica.
TL;DR: Three new specimens of Ectophylla alba and 2 of Vampyrum spectrum are reported from Costa Rica, and the Central American records for the 2 species are discussed.
Abstract: Three new specimens of Ectophylla alba and 2 of Vampyrum spectrum are reported from Costa Rica. The Central American records for the 2 species are discussed. Measurements, color notes and remarks on the natural history of the new specimens are included.
TL;DR: The first genomic resource for Ectophylla alba is presented in this article, which consists of 13 protein coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA genes (tRNAs), and a putative Control Region (CR) 1,232-bp in length.
