“…We obtained a total of 81 free-ight sequences of echolocation calls coming from 81 individuals from the family Vespertilionidae (Myotis albescens (10), M. keaysi (10), M. riparius (10) and Lasiurus blossevillii ( 10)), Molossidae (Molossus molossus (10), Tadarida brasiliensis (10) and Promops centralis (11)) and Emballonuridae (Saccopteryx bilineata (10)). For the ight room recordings, we obtained a total of 80 sequences coming from 31 individuals from all species except P. centralis since it was not recorded in ight room considering the evidence of the ight room consequences on high variation in their pulses and recommendations to avoid using these methods in species adapted to open areas (see Mora et al 2004; Martinez-Medina et al 2021; Table 2).…”

“…To get a rst view of the bat diversity in the area, we identi ed at the species level all the captured individuals. Then, we released some individuals (M. albescens (5), M. keaysi (1), L. blossevillii (1), M. riparius (2), M. molossus (10), T. brasiliensis (2) and S. bilineata (3) inside of a closed ight room (2 m long x 2 m wide x 2 m high, covered with mesh) and made focal recordings of their echolocation pulses while they were ying. We were not able to collect all the individuals captured, additionally, we take recordings in ying free (M. albescens (10), M. keaysi (10), L. blossevillii (10), M. riparius (10), M. molossus (10), T. brasiliensis (10), P. centralis (11), and S. bilineata (10)).…”

Diversity surveys may be performed by different sampling methods. In the case of bats, the use of traditional methods such as mist nets, harp traps, and roost detection have limitations in widely covering the diversity in a landscape. Most registered species are restricted to species that forage at the undergrowth or in enclosed spaces. However, acoustic monitoring is complementary to conventional methods and can help obtain more complete bat inventories while avoiding alterations in usual foraging activities and disruption in their life cycles. This study describes the acoustic parameters (spectral and temporal variables) of the echolocation pulses of insectivorous bats to characterise acoustically different species of bats present in southwest Colombia. We recorded echolocation calls between December 2017 and May 2020 in the Andean and Pacific regions of the department of Nariño. A total of 81 sequences from free-flying bats were analysed from eight species belonging to three families: Vespertilionidae, Molossidae and Emballonuridae. Myotis riparius and Lasiurus blossevillii were registered for the first time in Nariño Department. The species M. albescens, M. keaysi, M. riparius and L. blossevillii (Vespertilionidae) had pulses of frequency modulated with a quasi-constant ending; Molossus molossus, Tadarida brasiliensis and Promops centralis (Molossidae) had pulses with constant and quasi-constant frequencies; and Saccopteryx bilineata (Emballonuridae) had pulses with quasi-constant frequencies. This study enriches the efforts to solve acoustic species classification issues of insectivorous bats in the Neotropics.

Despite the high diversity of bats in neotropics, traditional methods such as mist nets, harp traps and roost detection have limitations in capturing that diversity in a landscape, with most detected species restricted to those that forage in the undergrowth or enclosed spaces. Therefore, acoustic records become a tool that complements and enhances the efforts to get more complete bat inventories while avoiding alterations in usual foraging activities and disruption in their life cycles. This study describes the acoustic parameters (spectral and temporal variables) of the echolocation pulses of insectivorous bats to characterise different species of bats in Southwest Colombia acoustically. We recorded echolocation calls between December 2017 and May 2020 in the Andean and Pacific regions of the Department of Nariño. We analysed 81 sequences of echolocation calls from eight bat species belonging to three families: Vespertilionidae, Molossidae and Emballonuridae. We perform recordings on free-flying bats with identity corroboration by capture for recording in flight rooms and examination in the hand. Myotis riparius and Lasiurus blossevillii were recorded for the first time in the Nariño Department. M. albescens, M. keaysi, M. riparius and L. blossevillii (Vespertilionidae) had pulses of frequency modulated (FM) with a quasi-constant frequency (QCF) ending; Molossus molossus, Tadarida brasiliensis and Promops centralis (Molossidae) had pulses with constant frequency (CF) and QCF; and Saccopteryx bilineata (Emballonuridae) had pulses with QCF. This study contributes to the efforts to facilitate the identification of insectivorous bats of the Neotropics using the acoustic monitoring approaches, represents a reference to compare the acoustic studies in Southwestern Colombia and contributes to increasing our knowledge of the bat diversity in the region.
