Spectacled Warbler (Curruca conspicillata)
Red Crossbill (Loxia curvirostra)
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.

CCVery similar to Parrot Crossbill, but has thinner neck, smaller head, steeper forehead and slender bill. Upper mandible is less curved towards the tip than in Parrot Crossbill, and the lower is straight, with no bulge. The tip of the lower mandible protrudes from behind the upper (tips of mandibles visibly crossing). The chest is less deep, and birds are not so front heavy. Large individuals may be difficult to identify because of overlapping characters with Parrot Crossbill. Plumage similar to Parrot, with dark wings and tail. Males with rufous red head and body, females green. Juveniles greyish green with streaking. Posture more erect than Parrot Crossbill, especially when foraging on ground.
Sound:Contact call similar to Parroy Crossbill's "tupp", but is on average higher and less powerful, with a "cut-off" ending. In sum: Parrot Crossbill; hard attack, soft ending, Crossbill: softer attack, cut-off ending. Beware regional variations and overlap in pitch of calls with Parrot. The song consist of improvised, resonant twittering, and series of contact calls with no apparent phrases. It is generally faster, with less marked pauses than in Parrot Crossbill, and the phrasing seems more random.
