Linnet (Linaria cannabina)
Great Black-backed Gull (Larus marinus)
In all plumages: Brown, unstreaked (or faintly streaked) back, grey bill, only faint wing-bars (or none), distinct white base to primaries and streaked throat. Both sexes with pale eye-ring and pale cheek patch. Breeding male distinct with slate grey head, cinnamon back, red chest and red forehead. Females and juveniles easily confused with Twite or Redpoll but note back and face pattern.
Sound:Flight-call a quick and "bouncing" "gig-gig" or "tchett-tchett". Most often disyllabic utterances, while Twite seems to vary more the number of syllables. Tone harder and more bouncing. Song a varied, sweet stream of contact calls, mimicry and trills with a staccato feel. Most easily recognized by the frequently interwoven, disyllabic contact calls.
