About These Birds
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.
Superb Fairywren
The superb fairywren is one of Australia's most beloved and recognizable birds, with breeding males dressed in spectacular violet-blue plumage. These tiny birds live in cooperative family groups where helpers assist the breeding pair in raising young. Males pluck and present yellow flower petals to females as part of courtship.
