extinction trees food corvids
Corvids are located throughout most of the world. They are found on all continents except Antarctica.
Members of this large family live in habitats ranging from treeless tundras where land is flat to mountain forests. Birds live in deciduous forests, where trees shed their leaves, and coniferous forests, with cone-bearing evergreen trees. Corvids range in deserts, grassland steppes where there are few trees, and on the edge of rainforests, where heavy rain produces much growth. In addition, corvids live in cities and small villages.
Corvids mainly eat seeds and nuts. However, they are omnivores, eat animals and plants. These birds are scavengers and take food from places like garbage dumps. Another corvid habit is hoarding food. Birds hide food, often burying it. They stockpile food for times like winter when there is a shortage of seeds and nuts.
According to the World Conservation Union (IUCN), the Hawaiian crow is Critically Endangered, facing an extremely high risk of extinction; four species are Endangered, facing a very high risk of extinction; eight species are Vulnerable, facing a high risk of extinction; and eleven species are Near Threatened, in danger of becoming threatened with extinction. The primary cause is the destruction of habitat as trees are cut down.
