According to the IUCN Red List, the total Snowy owl population size is around 28,000 mature individuals.

Population number.

[2] Just as these fascinating ecological relationships are being revealed, climate change appears to be influencing population cycles of arctic wildlife.

Female snowy owls lay from 3 to 11 eggs at a time, in a nest built on the ground. The owl population has seen a decline over the past decades caused by hunting, lack of prey and habitat, and viral diseases. Photo by Cassandre Crawford (Creative Commons). Several owl species prey on insects have seen numbers drop after consuming insects sprayed with insecticide and is most evident in the burrowing owl.

The European population consists of 700-2,300 pairs, … When there is plenty of food available, snowy owls tend to lay more eggs than when food is scarce. But during many winters, this large, white raptor comes to northern Minnesota to hunt voles, mice, and other small animals. In fact, if the downward trend continues at its current rate, an end to the Snowy Owls of our study area can be …

Snowy owl pairs usually mate for life. Lemmings make up the main part of the snowy owls' diet, and lemming population numbers rise and fall naturally. It seems that the snowy owl population undergoes an irruption every four years, so the winter of 2021–2022 is likely to be “snowier” than this one. A Snowy Owl in Cleveland, Ohio, on December 2, 2017. They spend summers far north of the Arctic Circle hunting lemmings, ptarmigan, and other prey in 24-hour daylight. Drivers of the decline are uncertain but likely include climate change affecting prey availability, as well as collisions with vehicles and infrastructure. With the snowy owl, there has been speculation and several recent studies on the relation between the snowy owl and lemming populations (Fears 2014; Smith 2014). The conservation status of the snowy owl is ‘Vulnerable’ . Snowy owls number around 200,00 but an exact population is hard to determine. But here’s what we can tell you: over 27 years of research, Snowy Owls have declined in our study area. Snowy owls also suffer from illegal hunting and are also often caught in fishing equipment. Threats to the snowy owl include hunting, starvation, plane strikes, vehicle collisions, and climate change. New reports are coming in at a moderate though not blistering pace.” Population Status Trend Notes Image Pernambuco pygmy owl: Glaucidium mooreorum: … Snowy owls rely on prey populations that fluctuate significantly over time. It is the only one featuring an all white coloring.

The snowy owl nests in the arctic tundra in northern Canada and Alaska. Identification. A lemming, the preferred food of the snowy owl.

This iconic large owl of Arctic regions has been uplisted to Vulnerable as it is undergoing rapid population declines in North America and probably also in northern Europe and Russia. Instead of seed crops, however, the Snowy Owl's populations and movements depend on populations of a small rodent — the lemming — whose abundance varies each year in well-documented boom-and-bust cycles.

General description: The snowy owl is a large, white owl with a round head, yellow eyes, no ear tufts and a black beak.

The population size was estimated to number approximately 200,000 individuals (Partners in Flight Science Committee 2013) (although there is some uncertainty over whether this refers to individuals or mature individuals), but recently, alternative methodologies have been presented which give far lower figures.
