Eli Kalko had a tremendous impact on our passion for bat research. She left us 15 years ago, but we work to keep her dream of studying and protecting bat species alive

So happy to share a new species record for our site: MacConnell’s Bat (Mesophylla macconnelli). It is the only species within the genus Mesophylla. Super cute, and tiny bat species! Remember, bats need friends!

Bats are everywere!

We wish this new year we will be more compassionate and empathetic towards them and all living beings, including ourselves…

We are thrilled to announce a new species record! For the very first time, Caracciolo's Stripe-faced Bat (Vampyrodes caraccioli). According to IUCN, its population trend is unknown. Food production and high biodiversity is possible!

The bicolor is back! We recorded Micronycteris tresamici (minuta), the Northern Big-eared Bat, for the second time. It belongs to a group of bats that are difficult to identify (tresamici vs minuta). According to Siles and Baker (2019), there are two possibilities:

a) both species are sympatric in Central America, or b) they are allopatric, with M. tresamici distributed from Guatemala to Costa Rica and M. minuta from Panama to southern Brazil.

More good news coming soon...

He did it again! Since 2022, the Velvety Fruit-eating Bat [Enchistenes hartii] has only visited us in June/July. This year we recorded it on July 31st, and it had Güitite [Wild tree to***co, Acnistus arborescens] seeds on its fur. Thanks for providing food and habitat for this and many other bat species!

Los murciélagos tienen un papel fundamental en la polinización, aunque este proceso está asociado generalmente con los colibríes y las abejas, este grupo de animales nocturnos son importantes polinizadores de las cactáceas columnares y también son importantes dispersores de sus semillas.💚

✅La selección de hojas para la construcción de tiendas por parte de algunas especies de murciélagos frugívoros de la familia Phyllstomidae es uno de los ejemplos más interesantes de la relación entre planta y animal

We have no words! It is not a just a new species for our study site, it is the holy grail of bats!
