01. Booted Warbler (Iduna caligata)
ID by Richard Grimmett : Small, with square-ended tail, and short undertail-coverts. Often shows faint whitish edges and tip to tail and fringe to tertials. Supercilium usually reasonably distinct and square-ended behind the eye, and can be bordered above by a diffuse dark line. Typically shorter- and finer-billed than Sykes's, with more prominent supercilium, and upperparts are warmer brown; it usually appears more Phylloscopus-like, owingto shorter bill, and more frequently feeds on the ground. Possibly confusable with Common Chiffchaff, but lacks any greenish or olive tones, and has pale base to lower mandible and pale legs. |
