Juvenile Balearic Warbler.

A good example of why, perhaps counterintuitively, identifying a bird from photos can be harder than doing so in the field. In the field, we'd have gained a good idea of the bird's shape, size, the colour of the tail, wings & upperparts and some idea of its behaviour & habitat preferences. Here we have essentially only have shots of the head and belly. Unfortunately, the greyish head, fine red eye-ring, white chin and dirty buff underparts could fit the female/young of several species - Balearic, Subalpine and Sardinian Warblers for example. However, the relatively fine and extensively yellow-based bill firmly suggests that it's a Balearic Warbler. Give me 30 secs of half-decent views of the living bird in the field and I'd be far more confident about its ID!
