Soman Ragavan :

Hello. I live in Mauritius, an island in the Indian Ocean. I will post some information I know about BATS and will ask you to comment on them, as well as to say what you find out about them during research you will make. Bats hibernate for half a year, during winter. They come out at night to search for food. There are many things special about them. Their eyesight is specifically developed, enabling them to see well at night or in the dark. They cannot stand light, by and large, although there might be some light while they come out at the start of the night and at the time they return to their caves in the early morning. They feed on fruits. In the caves, they hang by their feet. Though their heads remain down during the night and even for many months during hibernation, this does not affect them.

It is said that they each go back to their specific spots in the cave. Their droppings accumulate in the caves and possibly there are many infections in them. They breed at a high rate. It is said that Covid started at a bats market in China.

As they cannot stand light, they go back to the caves in the early hours of the morning. Once I saw a bunch of them hanging on a tree. They had remained back for too long while looking for food. As they could not stand sunlight, they slept on the tree during the day. Perhaps light adversely affects their eyes. I will write more as this chat proceeds. You can start commenting now.

Bats fly without making much noise. They have a terrific memory. They remember where the fruit trees are and navigate straight to them when they leave the caves. After feeding, they slug along heavily, because of the weight of the fruits they ate. I have seen some bats going in search of fruits early in the morning : those guys suddenly felt hungry again.

Certainly, let\'s analyze the information you\'ve provided about bats:

Observations:

• Hibernation: You\'re correct that many bat species hibernate during winter, reducing their metabolic rate to conserve energy.
• Nocturnal Activity: Bats are indeed primarily nocturnal, with most species emerging at dusk and returning to roosts at dawn.
• Vision: While bats do have some vision, it\'s not their primary sense. Many species rely heavily on echolocation to navigate and locate prey.
• Light Sensitivity: Some bat species are sensitive to light, but not all. The extent of their sensitivity varies.
• Diet: Fruit bats (megabats) are primarily frugivorous, while other bat species consume insects, nectar, blood, or even fish.
• Roosting Behavior: Hanging upside down is a common resting posture for bats, allowing them to quickly take flight.
• Droppings: Bat guano (droppings) can accumulate in caves and contain various microorganisms, some of which can be harmful.
• Reproduction: Bat reproduction rates vary depending on the species.
• COVID-19 Origin: While the exact origin of COVID-19 is still under investigation, it\'s believed to have originated in bats.

Points to Consider:

• Hibernation Duration: The duration of hibernation varies significantly among bat species.
• Light Sensitivity: The impact of light on bat vision needs further research. Some species may be more sensitive than others.
• Roosting Specificity: While some bat species exhibit roost fidelity (returning to the same roosting site), others may be more flexible.
• Disease Transmission: The risk of disease transmission from bats to humans is a complex issue.
• COVID-19 Origin: It\'s important to note that the link between bats and COVID-19 is still under scientific investigation.

I\'m ready to continue the discussion and delve deeper into specific aspects of bat biology as you provide more information.

I look forward to learning more about your observations!

Soman Ragavan :

Though they are largely quiet, it sometimes happens that they fight among themselves for fruits on the tree. Only when they fight do you hear them. With litchis and loganberries, they peel off the fruits and eat what’s inside.  In one night, they can devastate an entire loganberry tree. Fruit tree buyers hate them, as they finish off a lot of fruits in a single night. Fruit buyers can set up nets covering the tree, but bats will find a small gap, enter it and eat the fruits.

Google Gemini :  

This is fascinating! Your observations about fruit-eating bats causing significant damage to fruit crops are quite common. Here\'s a breakdown of your points and some additional insights:

Observations:

• Vocalizations: Fruit bats are generally quiet, but they can become vocal during feeding competitions or territorial disputes.
• Feeding Habits: They efficiently peel and consume the flesh of fruits like litchis and loganberries.
• Impact on Crops: A large colony of fruit bats can decimate a fruit tree in a single night, causing substantial economic losses for fruit farmers.
• Evasion of Deterrents: Nets and other physical barriers are often ineffective as bats can exploit small openings to access the fruit.

Additional Considerations:

• Ecological Role: While fruit bats can be a nuisance to farmers, they also play a crucial role in seed dispersal, contributing to the regeneration of forests and maintaining biodiversity.
• Human-Wildlife Conflict: The conflict between fruit farmers and fruit bats highlights the challenges of coexisting with wildlife.
• Sustainable Solutions: Research is ongoing to develop more effective and humane methods for deterring fruit bats from crops, such as acoustic deterrents or modifying fruit tree planting patterns.

Do you have any other interesting observations about the behavior of fruit bats in Mauritius? I\'d love to hear more about their interactions with other animals or their impact on the local ecosystem.

Soman Ragavan :

They avoid interaction with other animals. They come out at nightfall in groups for feeding. They keep themselves to themselves.

They have two front feet and two rear ones. With the rear feet, they hold on to a branch and with their front feet they grab the fruit and eat it. As mangoes are heavy for them to hold and their feet are small, quite often the fruit falls off. Frequently they won’t bother to come down to the ground to finish off eating. They will reach out for other mangoes. Thus, in the morning you will see many partly-eaten mangoes on the ground.

Google Gemini :

These observations provide further valuable insights into the behavior and feeding habits of fruit bats:

• Social Behavior: While they may form groups for feeding, your observation that they \"keep themselves to themselves\" suggests that fruit bats may not exhibit strong social interactions beyond basic group foraging.
• Feeding Mechanics: The description of their feeding technique, using their rear feet for support and their front feet for manipulating fruit, is accurate.
• Challenges with Large Fruit: Your observation that mangoes often fall during their feeding attempts due to their weight and the bats\' small size is quite interesting. It demonstrates the limitations of their feeding strategy and highlights the challenges they face when dealing with larger fruit.

These observations contribute to a better understanding of the ecological role of fruit bats in the Mauritian ecosystem.

Do you have any other interesting observations about these fascinating creatures? I\'m particularly interested in their roosting sites and any potential interactions you may have observed with other wildlife in Mauritius.

Soman Ragavan :  

They roost in mountain caves, at high places where predators have difficulty to get at them. Near my home (Stanley, Rose Hill, Mauritius) there is the Corps de Garde Mountain, which is about 2000 feet high. They stay in caves on the mountain.

As they finish off one tree after another, they fly farther and farther away in search of fruits. They have a very good memory about where to find fruits. Once they start with a tree, they come back to it the following night. When they have nearly eaten all the fruits on a particular tree, they won’t waste time to come back to it. They know how to avoid it.

Google Gemini :

Your observations about the roosting habits and foraging strategies of fruit bats are quite insightful:

• Roosting Sites: Choosing mountain caves as roosting sites provides several advantages for bats, including protection from predators and access to cooler temperatures.
• Foraging Strategies: Your description of their foraging behavior, including their tendency to return to productive fruit trees and their ability to quickly move on to new sources of food, demonstrates their adaptability and efficiency in locating food resources.

These observations provide valuable information about the ecological role of fruit bats in the Mauritian environment.

Do you have any other interesting observations about their behavior, such as their interactions with other animals, their role in seed dispersal, or any unique adaptations you\'ve noticed?

(11)

Soman Ragavan :

I heard that they give birth while still hanging with their feet from the cracks/rocks in the caves. Indeed, there is a clip on the Internet about this. At the time of giving birth, they spread out their wings and catch the young one in time. If they fail to do so, it will fall on the droppings on the floor. The young ones cling to the mother for a long time, until they can hang by themselves.

Most creatures are bound to feel bad effects by remaining with their heads down for a long time, as blood will accumulate in the head. But, bats appear to be designed to cope with this. Perhaps one result of hanging by the feet with the head down enables a large bunch of them to huddle together in a cave.

Google Gemini : 

These observations provide some fascinating insights into the reproductive behavior and unique adaptations of bats:

• Birth in Flight: The idea of bats giving birth while hanging upside down is quite remarkable. The ability to spread their wings and catch their young in mid-air demonstrates an incredible level of coordination and adaptation.
• Head-Down Posture: Your observation about the potential physiological adaptations that allow bats to tolerate hanging upside down for extended periods is intriguing. It highlights the remarkable evolutionary adaptations of these creatures.
• Social Behavior: Your suggestion that the ability to hang upside down may facilitate close proximity within the roost is a plausible hypothesis. This close grouping could provide benefits such as thermoregulation, social interaction, and protection.

These observations further emphasize the unique and fascinating biology of bats.

Do you have any other interesting observations or questions about bats in Mauritius? I\'m always eager to learn more about these fascinating creatures.

Soman Ragavan :

They operate in groups and avoid mingling with other creatures. They reproduce at a high rate. You rarely see very young bats. They remain in the caves until they can fly to far places.

Please make concluding remarks and make comparisons with other creatures that show similar skills.
