Поползень-великан Sitta magna

The largest nuthatch in the world, about the size of a bulbul. Coloration similar to many other nuthatches: gray above and white below, with a thick black line through the eye. Picky in its habitat preferences and as a result generally uncommon or absent through much of its range; requires extensive stands of mature tall pines in foothills and montane regions. Can be quite loud, giving a hoarse chatter reminiscent of a corvid; also gives a clipped fluty whistle.
