Perisoreus – Grey jays

This genus includes a group of birds commonly known as gray jays, Canada jays, or Siberian jays. These birds are members of the Corvidae family, which also includes crows, ravens, and magpies. Known for their intelligence, boldness, and adaptability, Perisoreus jays thrive in some of the harshest climates on Earth.

Perisoreus jays are medium-sized birds, typically measuring about 25 to 33 cm (10 to 13 in) in length, with a wingspan of 46 to 53 cm (18 to 21 in). They have thick, fluffy plumage that helps them stay warm in cold climates. The most distinctive feature of these birds is their soft, grayish coloration. The gray jay has a pale face with a dark cap, while the Siberian jay has a more uniform gray-brown color. The Sichuan jay, on the other hand, has a darker overall plumage.

Perisoreus jays are highly adaptable and thrive in cold, boreal forests. They are non-migratory, meaning they stay in their habitats year-round, even during harsh winters. These jays are known for their bold and curious nature, often approaching humans without fear. This behavior has earned the gray jay the nickname “camp robber” because they frequently scavenge food from campsites.

One of the most remarkable behaviors of Perisoreus jays is their food caching strategy. During the warmer months, these birds collect and store food in various hidden locations, such as tree crevices and under bark. They use their sticky saliva to glue the food in place, creating a cache that can be accessed during the winter when food is scarce. This behavior is crucial for their survival in environments where temperatures can drop significantly and food availability is limited.
