A dark, stocky warbler, the Cetti's warbler is most likely to be heard, rather than seen - listen out for its bubbling song among willow, marsh and nettles.

The willow tit lives in wet woodland and willow carr in England, Wales and southern Scotland. It is very similar to the marsh tit, but has a distinctive pale panel on its wings.

This slim fish is usually found on gravelly parts of the seabed, close to shore, but can turn up in rockpools.

As the bluebells fade, yellow archangel takes its turn to impress, with golden-yellow flowers carpeting our ancient woodlands.
