About These Birds
European Robin
The European robin is one of the most beloved birds in Britain, where it is the unofficial national bird. Despite its friendly demeanor toward humans, robins are fiercely territorial against their own kind, singing year-round to defend territory. Their distinctive song is one of the first to be heard at dawn.
Snowy Owl
The snowy owl is the heaviest North American owl and one of the most charismatic Arctic birds. Unlike most owls, it is largely diurnal, necessitated by the continuous daylight of Arctic summers. Snowy owl irruptions — periodic mass southward movements — are tied to lemming population cycles.
