Common redstarts, or simply redstarts, are breeding visitors that are only found in the UK between April and October. They generally inhabit scrubs, woodland, and parks.
Black redstarts are a rare breeding bird but can be seen all year round during passage particular in urban areas, although they will move into scrub and woodland for breeding season.
Males are fairly straightforward to tell apart when you know what you’re looking for but females are a little trickier.
