Godman's Long-tailed Bat

Godman's Long-tailed Bat is a small nectarivorous bat belonging to the leaf-nosed bat family, found from Mexico through Central America into northern South America. It is remarkable for its elongated rostrum and long extensible tongue, adaptations for feeding on nectar from tubular flowers. This species plays an important ecological role as a pollinator of night-blooming plants such as certain cacti and Bombacaceae. It is generally uncommon but widespread across lowland tropical forests.

Mexico, Central America, and northern South America (Colombia, Venezuela)

Ranges from southern Mexico (Oaxaca, Veracruz, Chiapas) through Central America (Belize, Guatemala, Honduras, Nicaragua, Costa Rica, Panama) into northern Colombia and Venezuela.

Altitude and depth

Typically found from sea level up to about 1,500 meters elevation.

Seasonal movements

No long-distance migration is documented, but local movements may track seasonal flowering of preferred nectar plants.

Primarily found in lowland tropical dry and moist forests, gallery forests, and forest edges, often near caves or rocky crevices used as roosts. It also occurs in secondary growth and disturbed habitats where nectar-producing plants are available.

Adaptations to its environment

Possesses an elongated snout and a long, brush-tipped tongue for extracting nectar deep within flowers, along with reduced dentition suited to a liquid diet. Its small size and maneuverable flight allow it to hover briefly while feeding.

Listed as Least Concern by the IUCN due to its wide distribution and presumed large population, though it is patchily recorded and considered uncommon in many areas.

Estimated population

No precise global population estimate exists; the population trend is presumed stable, though local declines may occur due to habitat degradation.

Habitat loss from deforestation, agricultural expansion, and disturbance of roosting caves are the primary threats. Pesticide use may also reduce availability of nectar and insect food sources.

Diseases and parasites

Like many bats, it may host ectoparasites such as mites and bat flies, as well as being a potential reservoir for certain bat-associated viruses, though specific studies on this species are limited.

The species benefits indirectly from protected areas and forest reserves within its range in Mexico, Central America, and Colombia. No species-specific conservation programs are currently in place.

Recommended actions

Recommended actions include protecting roosting caves, maintaining forest connectivity, and further research into population status and ecological requirements.

It has soft brownish-gray fur, a long narrow muzzle, small eyes, and a reduced tail that is largely enclosed within the interfemoral membrane. The nose leaf is small and simple, typical of nectar-feeding phyllostomids.

Size

Body length approximately 5-7 cm, with a forearm length of about 32-37 mm.

Weight

Typically weighs between 7 and 10 grams.

Distinctive features

Distinguished from related Choeroniscus species by subtle differences in skull shape, tooth structure, and forearm length; overall it is very similar in appearance to its congeners, requiring careful measurement for identification.

Differences between males and females

Sexual dimorphism is minimal, with males and females similar in size and coloration.

Generally roosts in small groups or solitarily in caves, hollow trees, or rock crevices, though larger aggregations may occur at favorable roost sites.

When it is active

Nocturnal, becoming active after dusk to forage for nectar and return to roosts before dawn.

Diet

Primarily feeds on nectar and pollen from a variety of night-blooming flowers, supplementing its diet with some fruit and insects.

How it feeds and hunts

Uses hovering flight and its long tongue to probe deep into tubular flowers, extracting nectar while inadvertently transferring pollen between plants.

Communication

Communicates through echolocation calls for navigation and social vocalizations within roosts; body contact and olfactory cues may also play a role in social interactions.

Interactions with other species

Interacts with various nectar-producing plants as a key pollinator and may share roosts with other bat species. Predators likely include owls, snakes, and small carnivorous mammals.

Role in its ecosystem

Serves as an important pollinator for various tropical plants, particularly those with bat-pollination syndromes (chiropterophily), contributing to forest regeneration and plant diversity.

Breeding details are not fully documented, but as with related species, gestation likely lasts around 3-4 months, with females typically giving birth to a single pup per litter.

Raising the young

Females carry and nurse a single pup, which clings to the mother during early development until capable of independent flight and foraging.

Maturity and lifespan

Sexual maturity is reached within the first year of life; lifespan in the wild is estimated at several years, though exact data are scarce.

Classification

Mammalia > Chiroptera > Phyllostomidae > Choeroniscus > Choeroniscus godmani

Scientific synonyms

Hylonycteris godmani; Choeronycteris godmani

Recent studies

Recent taxonomic and phylogenetic studies have refined the classification of Choeroniscus species using molecular data, helping distinguish it from closely related nectar-feeding bats.

Genome and DNA

Specific genomic studies on Choeroniscus godmani are limited, though phylogenetic analyses have helped clarify its placement within the Glossophaginae subfamily.

Compared with similar species

Similar to other members of the genus Choeroniscus, such as Choeroniscus minor, but can be differentiated through cranial measurements and geographic range; it is also ecologically similar to other glossophagine nectar bats like Glossophaga species.

Its tongue can extend far beyond its snout to reach deep into flowers, functioning much like a hummingbird's. Despite its small size, it plays an outsized role in pollinating night-blooming tropical plants.

Where and how to see it

Best observed at dusk near flowering plants such as Bombacaceae or columnar cacti in tropical lowland forests of Mexico or Central America; using a bat detector can help identify its echolocation calls.

Risks to humans

No notable risk to humans; it does not bite defensively and poses minimal direct threat.
