Cane Toads: Daytime Hideouts And Sleep Patterns

Cane toads are native to Central and South America and are members of the 'true toads' family Bufonidae. They are mostly nocturnal, but recent research has shown that they are becoming diurnal in response to novel conditions in their Australian invasion. During the day, cane toads sleep in burrows they dig into the earth and emerge after sunset to hunt for food. They prefer to sleep in cool, moist places during the day and can often be found under damp, rotting wood or large stones.

Where do cane toads sleep during the dry season?

During the dry season, cane toads tend to seek refuge in moist areas and forage for food. They are highly adaptable and can survive in a variety of habitats, including human-modified environments such as yards, golf courses, and agricultural areas. While they prefer warm, moist environments, cane toads can also survive in physiologically stressful conditions like droughts.

Cane toads are nomadic and do not have a defined home range, often moving more than 200 meters in a single night. They tend to move further during the wet season, especially on warm, wet, and windy nights. However, they can remain relatively active during the dry season by seeking shelter in burrows or other refugia.

During the day, cane toads typically hide in cool, moist places to avoid the sun, and they may excavate depressions beneath logs, rocks, and debris to shelter from the dry conditions. They are mostly nocturnal, but recent research has shown that they can switch to diurnal activity in response to novel habitat types or when facing nutritional stress, thermal extremes, or intraspecific competition for food.

In their native range, cane toads are found in greater densities in human-modified habitats than in natural settings. They are commonly found in open areas with permanent water sources nearby, such as temporary pools, ponds, and canals. While they are adaptable and can survive in various conditions, cane toads need access to water to survive and will seek out open dams or other water sources during the dry season.

What are the ideal sleeping conditions for cane toads?

The ideal sleeping conditions for cane toads are during the day, in cool, moist places out of the sun. They tend to shelter under leaf litter, rubble, or scraps of iron, and sometimes dig burrows. They also sleep in burrows during the cold winter months.

Cane toads are nocturnal, so they sleep during the day and emerge after sunset to hunt for food. However, they may occasionally pop out of their burrows during the day, especially during the breeding season.

Cane toads prefer to sleep in moist, warm environments, but they can survive in physiologically stressful conditions, such as droughts, by seeking refuge and foraging in moist areas. They are also able to survive a wide range of temperatures, from 5–37°C.

They do not have a defined home range and are nomadic, moving more than 200 meters in a single night. They tend to move further during the wet season on warm, wet, and windy nights.

Cane toads need access to water to survive and can be found near open dams, as they require water to cool down and hydrate in hot, dry conditions. They can spread out to waterless areas when it rains but cannot survive more than a couple of days without water.

Do adult cane toads sleep during the day?

Adult cane toads are generally nocturnal, meaning they are active at night and sleep during the day. However, recent studies have shown that some adult cane toads have shifted to diurnal activity, particularly in response to novel environmental conditions or food scarcity. This shift in activity patterns allows them to adapt to new habitats and exploit different food sources.

During the day, adult cane toads typically hide in cool, moist places, such as burrows they dig into the ground, or under damp logs, rocks, or debris. They prefer to stay in moist, warm environments, but can also survive in drier conditions by seeking refuge in moist areas. This behaviour is especially important in arid climates, where they need to visit water sources every few days to survive.

In their native range, adult cane toads are found in greater densities in human-modified habitats, such as yards, golf courses, and agricultural areas. They are highly adaptable and can be found in a variety of habitats, including savannas and open forests.

While adult cane toads are mostly nocturnal, tadpoles and younger toads are more active during the day. This difference in activity periods helps to prevent cannibalism by larger cane toads.

How does the weather impact cane toad sleeping patterns?

The weather has a significant impact on the sleeping patterns of cane toads. While adult cane toads are generally nocturnal, they have been observed to shift towards diurnal behaviour in response to specific weather conditions. This shift in activity is more common in hotter climates, where higher temperatures increase their metabolic rates and, consequently, their maintenance energy requirements.

In their native range, cane toads are typically found in tropical environments with high temperatures and humidity. They prefer warm, moist environments and tend to be more active during the warm months of spring, summer, and early fall. During the day, they seek shelter in cool, moist places, such as burrows, under leaf litter, or in crevices to avoid dehydration from direct sunlight.

However, in arid climates, cane toads have been observed to engage in a phenomenon called "phase shifting." They adapt to the dry conditions by becoming active during the day to hydrate and cool down, allowing them to survive in extreme temperatures. This behaviour is particularly noticeable in the Tanami Desert of Australia, where ground temperatures often exceed 40 degrees Celsius.

Additionally, cane toads are known to be opportunistic and adaptable. They can survive a wide range of temperatures, from 5 to 37 degrees Celsius, and are nomadic, moving more than 200 meters in a single night. They are more active during wet seasons and on warm, wet, and windy nights but can remain active during dry seasons by seeking moist areas.

In summary, the weather plays a crucial role in shaping the sleeping patterns of cane toads. While they typically prefer to be active at night, they demonstrate behavioural flexibility by adjusting their activity times based on weather conditions, particularly temperature and humidity, to ensure their survival in diverse environments.

What are the dangers of cane toad sleeping spots?

The dangers of cane toad sleeping spots are varied and depend on the location. In their native range, cane toads are found in greater densities in human-modified habitats than in natural settings. They are common in yards, golf courses, agricultural areas, and similar habitats. Their ability to exploit human-altered habitats is a common trait among invasive species, and cane toads have proliferated in these environments.

One of the main dangers cane toads pose is to native species, particularly predators, due to their toxicity. In Australia, for example, death rates are high among native animals that attempt to eat cane toads, including monitor lizards, freshwater crocodiles, and various snake species. The introduction of cane toads has led to a decline in native predator populations in affected areas.

Cane toads also pose a danger to domestic animals and pets. Dogs, in particular, are at risk of cane toad poisoning if they attack or try to eat one. Cats are also susceptible, though they are less likely to do so than dogs. The toxins in cane toads can cause severe symptoms in pets, including seizures and cardiac arrest, and can even be fatal.

In addition, cane toads can impact human well-being. Their loud calling can cause sleep disturbances in residential areas. The toxins secreted by cane toads can also irritate human eyes and skin, so they should be handled with care and gloves.

Furthermore, cane toads can negatively affect the abundance of bush foods, such as goannas, for Indigenous people in remote communities. Their presence may also lead to the unintentional destruction of native frog species, as people may have difficulty distinguishing them from cane toads.
