As a child, the entomologist George McGavin found a dead gannet on the beach, and set about extracting the skull for his collection. He was fascinated to discover the hundreds of pointed barbs in its mouth. Now years later he marvels at this clever bit of evolution which prevents fish falling out of gannets' beaks as they dive into the water then become airborne again.

CEO of the British Trust for Ornithology Juliet Vickery is particularly fond of brent geese, having studied them on the Norfolk coast for three winters. They are our smallest goose, which migrate from the Arctic Circle every year. She describes what she learnt about fluctuations in their population, and the fascinating connection with lemmings in the Siberian tundra.

Conservation biologist Tolga Aktas shares his fascination with watching jackdaws. He was struck by the contrast between its black plumage and piercing pale eyes, which they likely use as a communication tool. Jackdaws form large, noisy communal winter roosts with other species, and aren't afraid to mob predators behaviour which Tolga finds spectacular to see.

The poet and non-fiction writer Polly Atkin observes the wintering of short-eared owls in Cumbria. They are the UK's most nomadic owl, with residents joined by migrants from Scandinavia, Iceland and Russia, seeking a gentler version of the season. Fellow owl-lovers have told Polly of the moment they arrive exhausted at the coast, and she has watched a pair nest in a building site near the sea, concerned how they would survive.
Polly Atkin is the author of The Company of Owls (Elliott & Thompson).
