In the north and east of its range it is primarily migratory, whereas southern birds are resident. Overall, the indomitable Goldcrest has a much broader world range than the Firecrest, being found as far east as China, while the latter is almost confined to Europe.

There are some interesting behavioural differences between the two ѕрeсіeѕ.

It is often sited in ivy or other creepers, as well as sometimes high up in a conifer. And when Firecrests are displaying, they don’t nod like a Goldcrest to show off the crown. Instead, presenting their stripy heads as their most prominent feature, they simply look ѕtгаіɡһt towards each other.
