Great Slaty Woodpecker is a large gray woodpecker with two subspecies.
Great Slaty Woodpecker is a resident bird, often in small groups of 4 to 6. They live mostly in trees, often moving from one tree to another. They fly clumsily, flapping their wings vigorously, often making loud noises. They also fly high, sometimes flying over the highest treetops, chasing each other and chirping as they fly. They mainly feed on ants and insects, including Coleoptera, Lepidoptera, Geometridae larvae, Tettigoniidae, Acrididae, Noctuidae larvae, Leptinotarsa larvae, Sphenopsidae larvae, butterfly larvae, caterpillars, crickets, mantises and other insects, and also eat a small amount of plant fruits and seeds.
The Great Gray Woodpecker nests in tree holes, laying 3-4 eggs per nest. The size of the eggs is 32-43×27-35 mm, and the male and female take turns incubating the eggs.
The Great Gray Woodpecker has been listed as a vulnerable species due to its rapid population decline in the past 20 years due to the reduction of forest coverage.
