It can use a twig, stick or cactus spine to dislodge invertebrates from trees. It has a curved beak that is short. The other three tree-dwellers are the greater tree finch (Camarhyncus psittacula), the medium tree finch (C. pauper) and the small tree finch (C. parvulus). Large tree finch (Geospiza psittacula). They live in temperate forest, dry savannah and may also be found in dry forest and mangrove habitats in the tropical regions. Finch Information... Index of Finch Species.

There is also considerable evidence that some other finches, for example the American goldfinch ( Carduelis tristis ), will on occasions 'switch' to eating aphids. A Darwin Finch, Crucial to Idea of Evolution, Fights for Survival. DarwinвЂ™s Finches - Generalities. The finches that use tools, like the mangrove and woodpecker finches have adapted their behavior based on finding their food, which implies that they have higher foraging skills and that they have a higher intelligence, even though when scientists tested all finches, they were found to have the same level of cognitive understanding. A finch needs the nutrients found in nuts, seeds and birdseed. What are mangroves? The mangrove finch is named after the mangrove, the tree where it lives. A finch can eat a wide variety of fruits and vegetables. They inhabit grasslands, open forests, deserts, and the edges of rivers and ponds, but they also live in more urban areas.

This type of bird only lives and breeds in mangrove stands that are only found miles away from the sea. Then have students explore different mangrove ecosystems and construct an explanation for how developing a Marine Protected Area for a mangrove ecosystem could help preserve biodiversity. The Mangrove Finch loves to eat insects and often uses its sharp beak to find insects, such as larva and grubs, which often hide in pieces of dead wood. Finches do a lot of flying within their cage so make sure you get a large enough cage, at least 30x18x18 inches (Length x Width x High) for a pair. Woodpecker finch (Geospiza pallida).
