What You'll Learn
Australian crows' diet
The Torresian Crow, also known as the Australian Crow, is a large, glossy black crow with short throat hackles (feathers). It is found across northern Australia and in Western Australia, commonly in coastal and tropical areas. It is also found in Papua New Guinea, the Moluccas, and New Britain.
The Australian Crow has a varied diet that primarily consists of insects, small animals, seeds, fruits, and carrion. They are opportunistic and adaptable feeders, often changing their foraging habits in response to the presence of human settlements and food sources. In urban environments, they scavenge for food scraps, picnic leftovers, pet food, and insects in grassy areas and gardens.
The diet of the Australian Crow outside urban areas primarily consists of invertebrates, berries, and carrion. They have also been known to eat stranded fish on the seashore, roadkill, grain, smaller birds, and rodents. In Northern Australia, they have developed a technique to kill and eat the introduced poisonous cane toad by flipping it onto its back and consuming only the intestines and parts of the thighs, avoiding the poison.
The adaptability of Australian Crows to different environments and food sources highlights their intelligence and survival skills, making them a fascinating subject for ornithologists and nature enthusiasts.

Australian tarantulas' diet
Australian tarantulas are often referred to as 'bird-eating spiders', but this is a misleading moniker as they rarely eat birds. Instead, their diet primarily consists of insects, lizards, frogs, and other spiders. They are ground-dwelling nocturnal spiders and are known to feed on invertebrates, including insects and other spiders. Small vertebrates such as geckos, skinks, and frogs are also part of their diet.
Australian tarantulas have large, heavy bodies that vary in colour from dark chocolate-brown to reddish-brown or pale fawn, often with a silvery sheen. They are capable of producing a hissing noise when provoked, a trait shared with other Australian theraphosids. This hissing sound is produced by the spider stridulating a patch of setae associated with its chelicerae.
The diet of Australian tarantulas can be influenced by their habitat and the availability of food sources. The species Selenocosmia stirlingi, for instance, is found in a range of habitats from rainforest to desert, and its diet may vary accordingly.
Female Australian tarantulas spend most of their lives in their burrows, which are web-lined and located underground. The burrows provide a constant temperature, with the minimum temperature for activity being 20 degrees Celsius. The feeding and growth season for these spiders occurs when the temperature exceeds this minimum threshold, which is during the months of September to May. During the colder months and the hottest parts of summer, the burrows may be plugged.
Australian tarantulas have a slower metabolism compared to other pets, so they require less food. As ectotherms, their need for food is also temperature-dependent, and they can go for extended periods without eating.

Australian crows' eating habits
Australian crows are highly adaptable and intelligent birds with diverse diets. They are skilled hunters and opportunistic feeders, consuming a wide range of food sources depending on their environment. In natural habitats, their diet primarily consists of fruits, seeds, insects, small animals, and
Australian crows are known to feed on various insects, including grasshoppers, caterpillars, beetles, and spiders. They play an essential role in controlling insect populations by preying on both beneficial and troublesome species. Their diet also includes small animals, such as lizards, frogs, snakes, and birds, showcasing their versatility as predators.
In urban areas, Australian crows have adapted their foraging habits to include human-generated food sources. They scavenge for food scraps, leftover pet food, and picnic leftovers in cities and residential areas. Their ability to exploit human-generated food has led to changes in their traditional diet and reflects their intelligence and resourcefulness.
The Torresian Crow, also known as the Australian Crow, is a large, glossy black crow found in northern Australia and Western Australia. It has a varied diet, consuming fruits, insects, other invertebrates, eggs, garbage, and carrion (dead animals). This particular species of Australian crow is known for eating the most grain compared to other corvids.
While information specifically about Australian crows eating Australian tarantulas is scarce, it is likely that they do so opportunistically, given their diverse diet and the fact that tarantulas are arachnids that can be found in Australia.

Australian tarantulas' appearance
Australian tarantulas are large spiders with a body length ranging from 2 to 11 cm, and a leg span of up to 20 cm. They are often referred to as "bird-eating spiders", but this is a misnomer as they rarely eat birds. The name may come from their large size, with some sources stating that they can have a leg span of up to 22 cm and a body length of 6 to 9 cm. They have powerful, venomous fangs that can grow up to 1 cm long. Their body colour ranges from dark brown to reddish-brown or pale fawn, often with a silvery sheen.
The seven species of Australian tarantula are the Queensland whistling spider (*Selenocosmia crassipes*), barking spider (*Selenocosmia stirlingi*), brush tarantula (*Coremiocnemis tropix*), *Selenocosmia strenua*, *Selenocosmia subvulpina*, *Selenotholus foelschei*, and *Selenotypus plumipes*. The genus *Selenocosmia* can be found in New South Wales, Queensland, South and Western Australia, with *Selenocosmia stirlingi* being the most widely distributed species, also found in north-western Victoria.
The Queensland whistling spider is so named because it can produce a hissing noise when provoked, a trait shared with other Australian theraphosids. The barking spider is likely named for the same reason, as it can create a barking noise that mimics a dog. These noises are a defensive mechanism used to deter predators.
Australian tarantulas live in silk or web-lined burrows in the ground, which act as a safe place for the female to hide her egg sac. The burrows are permanent homes and can be identified by a flange of grass or leftover soil around the outer rim, with some having a thin film of web across the entrance. The depth of the burrow varies from 40 to 100 cm, with no relation to the size of the occupant.

Australian crows vs. tarantulas' intelligence
Australian crows, or corvids, are considered some of the most intelligent birds in the world. They have the largest brains in proportion to their body size and are often compared to primates in terms of intelligence. Crows have been observed to perform a range of complex tasks, such as using tools, "talking" to each other, stealing and hiding things, and even teasing other species. They also possess an innate sense of numbers and an understanding of recursion, a key feature of human language. Additionally, they are highly social, curious, and opportunistic, with exceptional long-term memory. Their intelligence is evident in their ability to adapt to different environments, especially urban areas, where they scavenge for food and exploit human-generated food sources.
On the other hand, Australian tarantulas, while not as widely studied as crows, are also fascinating creatures. They are known for their ability to produce whistling or barking sounds by rubbing modified spines on their front limbs. While they are called "bird-eating spiders," they rarely eat birds and mostly feed on insects, lizards, frogs, and other spiders. Australian tarantulas are skilled hunters and can even swim and coat themselves in air bubbles during the wet season. They are highly adaptable, with the ability to live in a variety of habitats ranging from rainforests to deserts.
In terms of intelligence, crows have been extensively studied for their remarkable cognitive abilities, social behaviour, and problem-solving skills. They have been known to use complex tools and exhibit behaviours similar to those of humans. While tarantulas may not possess the same level of intelligence as crows, they do have their own set of adaptations and survival strategies. For example, they can produce defensive poses and sounds to deter predators and have excellent grip and climbing abilities.
Overall, while both Australian crows and tarantulas are intelligent in their own right, crows are widely recognised as being exceptionally intelligent among the bird species. Their ability to adapt, problem-solve, and exhibit behaviours similar to primates sets them apart. Australian crows have demonstrated a remarkable ability to exploit urban environments and take advantage of human-generated food sources, further showcasing their intelligence and resourcefulness.
In the battle of wits, Australian crows would likely outsmart Australian tarantulas due to their higher cognitive abilities, complex social behaviour, and ability to utilise tools and language-like communication. However, tarantulas should not be underestimated, as they have their own unique adaptations and survival strategies that make them successful predators in their own right.
