Passeriformes - Sittidae - Sitta azurea (Burung Patuk Gunung)
Not the only blue nuthatch, but the bluest nuthatch. Unmistakable, with a dark head, pale eyering, white throat and breast, and dark-lined pale blue feathers on the wings. Gives quick, sharp, nasal “tzwp” or “tzwit” notes. Clambers up and down tree trunks, often in small parties; frequent member of mixed-species foraging flocks. Favors montane and hilly forests.
