Craen goron-goch, Grus japonensis. The second-rarest crane in the world, endeared as symbols of fidelity, longevity, good luck, peace, and long life. Famous for jubilant, synchronised dances enacted during courtship.

Craen llances, Grus virgo. The smallest crane in the world. In their yearly migrations from central Asia to India, they cross the Himalayas at altitudes of 26,000 feet to winter in warmer Southern climes.

Coch y berllan, Pyrrhula pyrrhula. An exceedingly shy animal, known to mate for life. Males were once highly prized as cage birds that could mimic complex tunes played on a flute or whistle.

Conure yr haul, Aratinga solstitialis. Also known as the sun parakeet, native to northeastern South America, understood to form monogamous bonds from a young age. Endangered due to habitat loss, hunting for plumage, and relentless wild capture for the pet trade. There are now more sun conures in captivity than in the wild.

Robin goch, Erithacus rubecula. An opportunistic passerine known as a friend to gardeners, looking to pluck worms and grubs from soil turned up by a shovel or garden fork. Notoriously territorial, only pairing for the breeding season before parting ways to live their solitary lives.

Grugiar, Lagopus muta. A resident of the Scottish Highlands. Its name descends from the Scottish Gaelic word for “croaker” - tàrmachan. They change colour seasonally, moulting out their mottled brown plumage for clean white feathers in time for winter.

Carw llychlyn, Rangifer tarandus. Known as reindeer in Europe, and only in North America if they have been domesticated. Endemic to the uppermost Northern hemispheres of the globe across Europe, Siberia, and North America. Both sexes grow and shed antlers annually: males carry theirs in summer, females in the winter.

Tylluan eira, Bubo scandiacus. Yellow eyes in owls signify a diurnal lifestyle. A 5-foot wingspan, silent flight and 270° neck rotation makes the snowy owl an effective hunter. Pairs are often monogamous and raise their broods together.
