Eurasian Wryneck
Jynx torquilla
The Eurasian wryneck is 16–18 cm (6.3–7.1 in) in length. The nominate subspecies weighs 23 to 52 g (0.81 to 1.83 oz), and subspecies Jynx torquilla tschusii weighs 26 to 50 g (0.92 to 1.76 oz). It is a slim, elongated-looking bird with a body shape more like a thrush than a woodpecker. The upperparts are barred and mottled in shades of pale brown with rufous and blackish bars and wider black streaks. The rump and upper tail coverts are grey with speckles and irregular bands of brown.

Red-throated Wryneck
Jynx ruficollis
The red-throated wryneck grows to about 19 cm (7.5 in) in length. The sexes are very similar in appearance, and cannot be distinguished in the field, but the male averages 2–3% larger than the female, has a shorter tail, and is heavier at 52–59 g (1.8–2.1 oz) against her 46–52 g (1.6–1.8 oz). It is a slim, elongated bird with a small head, fine bill, long fan-shaped tail and a body shape unlike that of a typical woodpecker. The overall impression is of cryptic plumage patterned with greys, browns and black. Voice: The call of the red-throated wryneck is a series of repeated harsh, shrill notes kweek-kwik-kwee-quee, usually slower than the call of the Eurasian wryneck. It is a far-carrying territorial call given from a prominent perch. There is also a peegh alarm call followed by a repeated harsh krok. Young in the nest make wheezing squeaks initially, later a repeated buzzing tsch.
