“…Unlike D. watsoni , female E. alba are known to participate in the tent-making process [34]), suggesting that females may aggregate at tents for reasons other than access to a male-controlled resource. Further, stable groups exhibit high roost fidelity, suggesting that returning to the same location repeatedly may generally be an effective method for maintaining group cohesion.…”

“…Tent lifespan ranges from a few days up to eight weeks [33]. E. alba is most commonly found in mixed-sex groups [30], [31] and females have been observed participating in the tent construction process [34]. Caribbean white tent bats maintain long-term associations with specific individuals, and groups have even been documented switching to new tent roosts together [31].…”

Social Calls Produced within and near the Roost in Two Species of Tent-Making Bats, Dermanura watsoni and Ectophylla alba

Social animals regularly face the problem of relocating conspecifics when separated. Communication is one of the most important mechanisms facilitating group formation and cohesion. Known as contact calls, signals exchanged between conspecifics that permit group maintenance are widespread across many taxa. Foliage-roosting bats are an excellent model system for studying the evolution of contact calling, as there are opportunities to compare closely related species that exhibit major differences in ecology and behavior. Further, foliage-roosting bats rely on relatively ephemeral roosts, which leads to major challenges in maintaining group cohesion. Here, we report findings on the communication signals produced by two tent-making bats, Dermanura watsoni and Ectophylla alba. We found that both species produced calls in the early morning near the roost that were associated with roostmate recruitment. Calling often ended once other bats arrived at the tent, suggesting that calls may be involved in roostmate recruitment and group formation. The structure and function of these calls are described and future research directions are discussed.

“…Roost construction appears to be under sexual selection because shelters are typically constructed by single males [31,35] and occupied by them and one or more females [36]. However, females also make tents in some species [37]. Whether or not their construction costs are reduced through cooperative tent-building is unknown.…”

One contribution of 18 to a theme issue 'The evolution of cooperation based on direct fitness benefits'. Many bats are extremely social. In some cases, individuals remain together for years or even decades and engage in mutually beneficial behaviours among non-related individuals. Here, we summarize ways in which unrelated bats cooperate while roosting, foraging, feeding or caring for offspring. For each situation, we ask if cooperation involves an investment, and if so, what mechanisms might ensure a return. While some cooperative outcomes are likely a by-product of selfish behaviour as they are in many other vertebrates, we explain how cooperative investments can occur in several situations and are particularly evident in food sharing among common vampire bats (Desmodus rotundus) and alloparental care by greater spear-nosed bats (Phyllostomus hastatus). Fieldwork and experiments on vampire bats indicate that sharing blood with non-kin expands the number of possible donors beyond kin and promotes reciprocal help by strengthening long-term social bonds. Similarly, more than 25 years of recapture data and field observations of greater spearnosed bats reveal multiple cooperative investments occurring within stable groups of non-kin. These studies illustrate how bats can serve as models for understanding how cooperation is regulated in social vertebrates.

“…Female Ectophylla alba in Costa Rica have been observed building (Rodríguez‐Herrera et al . ), but it is possible that tent‐building by male bats may function to attract females (Hodgkison et al . , Kunz & Lumsden , Chaverri & Kunz ).…”

The dynamics of tent‐roosts in the palm Sabal mauritiiformis and their use by bats in a montane dry forest

et al. 2018

Tent‐making bats modify leaves to build refuges. Leaf modification involves energetic and defense costs that should be balanced by the benefits of tent‐roosting. The alteration of the leaf's vascular system reduces the tent's life expectancy, so to obtain a benefit, bats are expected to use tents regularly as long as they remain functional and not modify more leaves than necessary. Over 2 yr, we documented the dynamics of tent construction and use by Uroderma convexum and other bat species in the palm Sabal mauritiiformis in a Colombian transitional dry forest. We also assessed tent condition and compared it to nonmodified leaves of approximately the same age in focal palms. Probability of tent use by U. convexum varied between 57 percent during a reproductive period and 4 percent outside of this period. Bats cut the main vein of folioles, partially affecting water transport in the leaf. However, there were no differences between tents and nonmodified leaves in deterioration scores or deterioration rates over 1 yr. During 2 yr, 48 tents were lost for different causes, but this loss was balanced by the construction of 51 new tents. Thus, bats maintained an excess of usable tents. Palm leaves are long‐lived and seem preadapted to sustain damage and remain viable, particularly in species growing in dry environments. We present several hypotheses to explain the advantage of maintaining a tent surplus.
