I'm 6 months into Bird Watching and starting to get to grips with ID, but do struggle with Warblers. I wondered if anyone could help with this one please. The pictures were taken this week at a Cambridgeshire gravel pit.
You’re very welcome! Welcome to Birdforum btw. If you haven’t already, you could do worse than invest in a good field guide - (Collins is generally rated as the standard text and it’s available as an App too).
