Cormorant (Phalacrocorax carbo)
Merlin (Falco columbarius)
Easily confused with Shag when not in breeding plumage. Cormorant is larger, heavier built, has a thicker neck and less rounded profile. Head diagnostically wedge-shape, with the back of the head as the highest point. Bill never yellow (but yellow naked area at base of bill). Juveniles usually with whiter belly than Shag, and with less brown tinge. Behavioural differences from shag; often dives without jumping, more common in brackish water, often flies high, and often chooses higher ground or objects when perching. Slower wing-beats than Shag, with more separated primaries. Subspecies sinensis with larger gular poach angle (se fig.).
Sound:Mostly heard at breeding ground. Coarse, vibrating calls "hahahahaharo". Also deep, rattling and creaking sounds.

Smallest falcon. Male with slate grey upperparts, and pinkish buff, speckled underparts . Female dark brown above and heavily speckled below. Due to the extensive markings, the underparts give a darker impression than in Kestrel. Tail of female with dark broad bands, tail of male with broad black terminal band. Diffuse facial markings. Short wings. Silhouette similar to Peregrine, but the much faster wing beats are diagnostic. Acrobatic flight with sharp twist and turns when chasing prey. Alternating glides and bursts of wing-beats gives undulating flight.
Sound:Series of harsh "kwik-wik wik". Coarseness similar to Peregrine, but pace much quicker. Female call harsher than male. Lacking the clearer tones and attack of Kestrel.
