Yellow-legged Gull (Larus michahellis)
Green Woodpecker (Picus viridis)
Very similar to Herring Gull, and not always possible to identify with certainty. Generally thicker neck, rounder head and longer wings than Herring Gull. Adults: Silvery upperparts, bright yellow legs (beware that it is not uncommon for Herring Gull to have yellow legs!), and more black and less white in wing-tips. Bill heavier than H.G. with markedly curved tip. Orbital ring red, not orange. Big, red gonys spot, often extending to upper mandible. Marked gonys angle. Primary feather P5 (counted from innermost feather in gulls) usually with broad, black band. In winter plumage head is less streaked than in H.G., and often completely white. Immatures first winter: Pale belly and head. Dark underwings with blotchy markings. Only vague pale window of inner primaries, and well defined, wedge-shaped tail-band. Dark base of bill. For a detailed account of all plumages see Gull Research.
Sound:Voice more nasal than Herring Gull, but ID by sound difficult.

CCMedium sized, green woodpecker with black mask. Crown red in all plumages. Females with black moustache stripe, males with red framed in black. Juveniles heavily marked with small black and white spots all over, and less prominent black mask. Bigger and more heavily built than Grey-headed Woodpecker, with longer and stouter bill. Often foraging on the ground. Flight undulated.
Sound:Song similar to Grey-headed Woodpecker, but not as soft and fluty. Each phrase consist of a series of short "klee", with a laughing quality. Pitch drops slightly throughout the phrase, but not as markedly as in Grey-headed, and tempo is fairly constant (no ritardando). Short "kek" calls when excited and in flight. Drumming of 1.5 seconds duration with decelerating tempo, but not often heard. Another call is similar to Black Woodpecker; a series of resonant "klit-klit-klit-klit-klit-klit", but is less clear, has a more determined start and has less obvious rising pitch at the end of each syllable.
