Hello Mike,
first picture shows two Reed Warblers. Left bird is more easy by
- full, slightly rounded tail lacking whitish edges
- the right brown shade
- long, slender bill for a Warbler adds to an acrocephalus-jizz against other warblers
Right bird: I cant see anything wrong for a Reed Warbler (I would like to learn if a Marsh warbler can be excluded just by very long appearing claws, I am very intereste in this topic!)
Second picture shows a Reed Warbler, too by
- the same right brownish hues
- head profile is even more typical and id-friendly with snout, long head merging in a long bill
Agree, third is a Common or Lesser Whitethroat by
- whitish outer tail
- different jizz with rounded head and smaller bill with different shape
But which one?
- pale legs with a just visible yellowish/grenish tinge is just within variation for a Lesser, but also good for a Common (when picture quality is considered)
- overall colours are darkish and cold, so at first seems better for a Lesser
- but its hard to exclude a very worn, drab Common, for which bill shape seems slightly better
Do you have more pictures? I am not at best device to judge faint hues, but somehow it gives a Common WT jizz to me, but I am unsure.
Third is one for the real experts. But despite longish looking legs (is that really a field-mark?) it gives a Whimbrel-jizz to me:
- drab, dark-jizz
- Whimbrels are often more approachable than Curlews
