Frogs and tadpoles
The green tree snake is a diurnal species, meaning it is active during the day and rests at night. This behaviour aligns with the habits of many frog species, which are also active during the day, making them readily available prey for the green tree snake. The snake's large eyes and excellent eyesight allow it to spot frogs and tadpoles from a distance, giving it an advantage when hunting.
The consumption of frogs and tadpoles by green tree snakes plays a crucial role in maintaining the balance of ecosystems in Australia. By preying on these amphibians, the snakes help regulate their populations, preventing overpopulation and ensuring a healthy ecosystem. This relationship between predator and prey contributes to the overall biodiversity and ecological stability of the regions inhabited by green tree snakes.

Fish
Australian green tree snakes, or common tree snakes, are native to many parts of Australia, especially in the northern and eastern coastal areas, and to Papua New Guinea. They are slender, agile snakes with large eyes and keen eyesight. They are active during the day and sleep at night in hollow trees, logs, foliage, rock crevices, narrow caves, or abandoned buildings.
As for their diet, fish is one of the food items that Australian green tree snakes consume. They are opportunistic feeders and will occasionally prey on animals outside their normal diets. In the wild, they are known to eat small fish, in addition to their more typical diet of frogs, tadpoles, lizards, geckos, skinks, and small mammals.
In captivity, the feeding habits of green tree snakes can vary. Some individuals may readily accept fish as food, while others may be more reluctant to do so. It is important to note that there have been concerns about the potential for Thiaminase deficiency when feeding certain types of fish, such as goldfish, to green tree snakes. However, some snake owners have reported successfully feeding their pet snakes wild-caught mosquito fish, captive-bred guppies, and goldfish without any issues.
The preference for fish as a food source may also depend on the individual snake's tastes and previous feeding experiences. Some snakes may develop a preference for certain types of prey, while others may be more open to trying new food items. It is always important to provide a varied and nutritious diet for captive green tree snakes, and fish can be a part of that diet when supplemented with other food sources.
In addition to fish, captive green tree snakes are often fed a variety of other food items, including pinky rats, mice, lizards, geckos, and frogs. It is important for snake owners to ensure that their pet snakes are getting a healthy and balanced diet, and to consult with reptile experts or veterinarians if they have any questions or concerns about their snake's feeding habits.

Small mammals
The Australian green tree snake, or common tree snake, is a slender, diurnal, non-venomous snake species native to many parts of Australia, especially in the northern and eastern coastal areas, and to Papua New Guinea. It is one of the most commonly sighted snakes in suburban backyards, parks, and even inner-city gardens.
The green tree snake is an agile and active hunter during the day, preying on small animals such as frogs, water skinks, small reptiles and their eggs, small fish, geckos, and turtle hatchlings. While small mammals are not their primary source of food, they do form a part of their diet.
The green tree snake is a species of the Dendrelaphis punctulatus family, characterised by its slender body and tail, and large eyes with golden-coloured irises. Its colour can vary from golden yellow, bright green, olive-green, or dark brown to black, and even blue in some rare cases.
The small mammals that the green tree snake may prey on can include rodents such as mice, rats, and small possums, depending on the size of the snake. The green tree snake typically grows to between 1 and 1.5 metres in length, but some have been recorded at over 2 metres, and females tend to be larger than males.
These snakes are often found in trees, gardens, and near water sources, such as the well-vegetated banks of rivers, creeks, and streams. They are known to be reluctant to bite and will usually try to escape when threatened, only defending themselves by producing an odour from their cloaca and inflating their bodies to appear larger if they feel cornered.

Lizards and geckos
Green tree snakes are also known to eat small reptiles and their eggs. They are not picky eaters and will also consume tadpoles, frogs, locusts, small skinks, and even fish and small mammals. They are carnivorous and will prey on a variety of aquatic animals.
The diet of the green tree snake is influenced by its habitat, which includes grasslands, eucalyptus forests, and dense rainforests across northern and eastern Australia. They are commonly found in suburban backyards, parks, and inner-city gardens, where they can easily access their preferred food sources.

Birds and their eggs
The Australian green tree snake, also known as the common tree snake, is a slender, diurnal, non-venomous snake species with large eyes and excellent eyesight. It is native to many parts of Australia, especially the northern and eastern coastal areas, and can also be found in Papua New Guinea and some surrounding islands.
Regarding their diet, birds and their eggs are a significant food source for these snakes. The green tree snake's agility, speed, and keen eyesight make it well-suited for hunting birds. They can be found in a variety of habitats, including grasslands, eucalyptus forests, and dense rainforests, which provide ample opportunities for ambushing avian prey.
The green tree snake's diet consists of a variety of bird species, ranging from small songbirds to larger birds such as pigeons or doves. They typically target adult birds, but they may also prey on bird eggs, especially those that are easily accessible in nests located within their hunting range.
The hunting strategy of the green tree snake involves stealth and precision. They often hide in long grass or shrubs near water sources, waiting for their prey to come to nearby rocks or banks to drink or bathe. With their well-camouflaged bodies and excellent eyesight, they can remain motionless until the right moment to strike, using their speed and agility to capture their bird prey.
The consumption of bird eggs by green tree snakes is an important aspect of their diet, especially during the breeding season of their avian prey. The snakes may locate nests by chance or through their ability to sense chemical cues in the environment. Once a nest is located, they may consume the eggs, providing them with a rich source of protein and other nutrients.
Overall, birds and their eggs are an essential component of the Australian green tree snake's diet. Their hunting strategies and physical adaptations make them efficient predators of avian species, contributing to their ecological role in the diverse Australian habitats they inhabit.

They often hunt near water, hiding in long grass and waiting for prey to come to nearby rocks or banks.
Green tree snakes are non-venomous and rely on their agility, speed, and keen eyesight to catch their prey. They are diurnal, meaning they are active during the day and sleep at night.
Australian green tree snakes are oviparous, meaning they lay eggs. A typical clutch contains 5-12 elongated eggs. When they hatch, the snakes are a little over 10 inches (26 cm) long.
