In the second of our series of videos aimed at helping with the tricky task of identifying warblers, we take a look at Blackcap and Garden Warbler. BirdTrack reports show that Blackcaps are now here in significant numbers and garden warblers are just arriving so it’s a good time to brush up on the songs and ID features of these two common species.
This is called Getting to grips with warblers 3 : Reed Warbler Vs Sedge Warbler.
