Juvenile Reed Warblers at Belle Tout
The Migration Atlas states that up to 30% of Reed Warblers are double-brooded. The first brood juveniles are similar in their timings of their Autumn migration to adults in that they start to leave their breeding sites in late July, with their peak passage across the south coast in the last third of August. Juveniles are characterised by their warm rusty-brown upperparts and buff flanks.
