Three-toed Woodpecker (Picoides tridactylus)
Arctic Warbler (Phylloscopus borealis)
Shows no red patches in any plumages. Only woodpecker in WP with barred flanks. White stripes extends from behind eye to back and from base of bill to scapulars, but head is generally much darker than in other pied woodpeckers. Crown in male yellow, in female speckled white.
Sound:Drumming powerful and slow, with each beat clearly distinguishable. Most similar to Black Woodpecker but not as long (1 - 1.4 seconds). Accelerated ending (just the last few beats). Contact call similar to Great Spotted, but deeper and softer. Not very vocal.

Like a large Willow Warbler, with distinct dark eye-stripe. Supercilium marked, but narrow. Starts at base of bill, continuing far behind eye. Wing-bar distinct on greater coverts, and sometimes on median coverts too. Primary projection long. Bill long and relatively heavy with orange base. Flanks often slightly grey, and throat sometimes with faint streaking. Appearance robust, but elegant. Moves faster and with more confidence than congeners.
Sound:Call and song diagnostic. Song a rattling series of 20-30 single syllables. Repeated as a monotonous phrase in stable pitch, lasting 2-4 seconds. Starts more softly with volume rising throughout each phrase. Contact call equally unique. A hard and short "tsrrt", recalling contact call of Dipper. Often given as introductory part of song.
