Monotonous series of chirping 'cheep' and 'chirrup' notes. Male gives 'chilp' song repeatedly. Flocks produce constant chirping chatter. No melodic song; purely functional calls.
Snowy Owl
Male gives a deep booming hoot 'hooooo' and a rising 'hoo-hoo' series. Also barks sharply when alarmed. Quieter than many owls; silent during long Arctic winter hunts.

About These Birds
House Sparrow
The house sparrow is perhaps the most successful bird in the world at living alongside humans. Introduced to New York in 1851, it spread across North America within decades. Despite its global abundance, house sparrow populations have declined significantly in parts of western Europe.
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.
