As autumn takes hold, one of Britain’s tiniest birds is making one of the season’s most remarkable journeys.

Goldcrests can be seen throughout the year, but in autumn Britain’s resident population is joined by large numbers of migrants arriving from Scandinavia and Russia. These tiny travellers cross the North Sea, with many first touching down along Britain’s east coast before moving on to spend the colder months here. 

It is an extraordinary feat for a bird weighing just 5–6g. The goldcrest (Regulus regulus) vies with the closely related firecrest for the title of Britain’s smallest bird, yet each autumn migrants make a sea crossing that seems completely out of proportion to their diminutive size.  

Indeed, people once found the journey so difficult to believe that folklore suggested goldcrests hitched a lift across the sea on the backs of migrating woodcocks, earning them the nickname ‘woodcock pilots’.

Their regal name comes from their most striking feature. Goldcrests are tiny, olive-green birds with pale underparts and a brilliant stripe along the top of the head. Females have a yellow crown, while males show vivid orange at its centre. Their scientific name translates as ‘little king’ or ‘prince’, another nod to that colourful crown. The similar Firecrest is a much rarer bird, with a black eyestripe and broad white eyebrow stripe.

Keep an eye on conifers and mixed woodland, as well as parks and gardens with mature trees. Goldcrests are constantly on the move, searching among needles and foliage for tiny invertebrates. Their thin beak is ideally suited for picking insects out from between pine needles, and they often dangle upside down as they hunt for insects hidden in the foliage. During winter, they often join roaming flocks of other small woodland birds. 

Local sightings do occur, although anyone hoping to witness larger autumn arrivals may have more luck travelling eastwards towards Britain’s North Sea coast, where migrant goldcrests can appear in impressive numbers after their crossing.
