Goldcrest (Regulus regulus)
Pallid Harrier (Circus macrourus)
Smallest bird of Western Palearctic. Crown stripe yellow in female, orange in male. Since bird is often viewed from below, the crown stripe is often not visible. The dark eye with the large, pale grey eye-ring is a better character. Pale wingbars and pale tips of tertials. No supercilium. Behaviour essentially tit-like. Restlessly moving among branches in treetops, with frequent hovering to get at insects.
Sound:Contact call a very high pitched "zit zit zit", only similar to Firecrest and treecreepers. Treecreepers usually calls with longer "zzzziiiiit" repeated at regular intervals, while Goldcrest calls in phrases with two to four calls in series in an uneven rhythm. Firecrest contact calls lower pitched than Goldcrest, and in a softer tone (but quite similar). Song: a very high-pitched, undulating series of arpeggiated notes moving down and up again, repeated 4-5 times ending with a marked "conclusion" (like "trying to start a tiny motor and failing"). Timbre of song similar to contact call.

CCSlender and elegant harrier, with narrow wings and four "fingers". Adult male easily recognized by very pale grey and white plumage, with diagnostic wedge-shaped, black wing-tips (outermost primary grey). Female and immature birds often difficult to tell from Montagu's Harrier and Hen Harrier. Adult female differs from Montagu's by lack of dark band on upper wing, and by diffuse, sooty inner underwing. Pale bands do not reach wingpit, and under coverts are darker. Differs from female Hen Harrier by noticeably slimmer wings (both hand and arm) and only 4 fingers (but beware moulting Hen Harriers). Immature similar to Montagu's with unstreaked, rufous underparts. Differs in pale tips of inner primaries, and dark half-collar and pale "boa".
Sound:Some calls similar to Montagu's and Hen Harrier, but display call quite diagnostic. A thin, vibrating trill "peerrrrrrrr".
