The linnet can be seen on farmland and heathland across the UK. But, like so many other farmland birds, linnets are declining rapidly, mainly due to agricultural intensification.

The sessile oak is so-called because its acorns are not held on stalks like those of the familiar English oak. It can be found in woodlands mainly in the north and west of the UK.

This common hoverfly is often seen visiting flowers. It's named for its stripy thorax, which looks a bit like a football shirt.

The coal tit is mainly found in coniferous woodland, but can also be spotted in gardens and parks. It is smaller than the great tit, but has a similar bicycle pump-like song.

The grey long-eared bat certainly lives up to its name - its ears are nearly as long as its body! It mainly forages over grassland and meadows, but is very rare in the UK.
