Distribution Widespread bird breeding from Western Europe to Far East, China and northern India. It is breeding uniformly all over Estonia.
Abundance The population has remarkably increased in Estonia up to 30,000 - 50,000 pairs today.
Habitat It prefers various coniferous and spruce-dominated forests, also can be found in broad-leaved wooded meadows of Western Estonia.
Migration A part of Estonian population is sedentary, the other part is migratory arriving in March or early April. The autumn migration takes place mostly in September and October.
Feeding Jay is an omnivorous bird. In spring and in summer it feeds mostly on insects, worms, eggs and nestlings of smaller birds. At the end of summer it starts feeding also on seeds, berries and acorns.
Breeding The nest is most frequently built into a hardly noticeable place in a spruce in the height of up to 10 metres. Both parents take part in building it. The nest is rather flat consisting of twigs outside and softer material, mosses and grasses inside. The eggs are greyish-green with brownish pattern.
Development The hatching time is 16 - 17 days. Both parents hatch eggs and feed the nestlings afterwards. The young are altricial and they leave the nest at the age of three weeks. Parents take care of the young until autumn. At that time they wander around together. Average lifetime is 1.2 - 1.6 years.
The place in the ecosystem As an insectivore Jay eats various pests, being therefore useful for forestry. Also it helps to spread various plants.
Endangerment and protection Jay is not under protection.
