Spectacled Warbler (Curruca conspicillata)
Shag (Gulosus aristotelis)
Small and short-winged Sylvia with large head and high crown. In all plumages; evenly warm rufous wing-panel (lacking dark centered greater coverts of Whitethroat), very short primary projection, dark tail, thin pointed bill, narrow dark centres to tertials, pure white chin and (incomplete) white eye-ring. Adult male with lead-grey head, dark/black lore and often grey lower throat. Female and immature differs from Whitethroat by short primary projection, smaller size, slender build and thinner bill. Told from immature Subalpine Warbler by warmer rufous wings with only narrow dark centres to tertials.
Sound:Alarm call a dry, mechanical rattle; "trrrrrrrrrrrt", often rather long, but also given in pulses "trrrrrt-trrrt-trrrrrrrrr". More confluent and softer than similar call of Sardinian Warbler. Song rather weak and squeaky, but may be confused with several congeners. It typically starts with a few fluting notes then quickly giving way to fast alternating between clear tones and rattling pulses of "trrrrt". Phrases are short with marked pauses in between, and the structure is quite fixed even though each phrase is slightly different (in contrast to Sardinian and Subalpine Warbler). Sometimes bursts out in longer, more continuos flight-song.

CCEasily distinguished from Cormorant in breeding plumage, but at other times easily confused with congeners. Smaller than Cormorant, with a more slender neck and rounded head. Bill slender and straight. Steep forehead with peaked front crown, differs from the wedge shaped head of Cormorant. Bill often with yellow tinge (never in Cormorant). Flies with quicker wing-beats and straight neck (Cormorant with bulge). Often dives with a high jump. Juveniles with darker underparts than Cormorant, and often an obvious brownish tinge. Rare in brackish water.
Sound:Very deep and harsh voice heard at breeding ground. Deep grunts alternated, or ended with clicking sounds.
