Firecrest (Regulus ignicapilla)
Great Black-backed Gull (Larus marinus)
Distinct head markings, with black eye-stripe contrasting with broad, white supercilium. Top of head yellow (female), or orange (male), framed by black crown stripes. Characteristic orange shoulder patch, lacking in all confusion species. Immature is distinguished by present supercilium, other head markings absent.
Sound:Call: a thin "tsi tsi tsi" similar to Goldcrest, but not so sharp. Song: Similar in timbre to Goldcrest, but much more monotonous. A slow crescendo of short "tze" sounds in a phrase rising slightly in pitch, without the repeated arpeggiated movements of goldcrest.
