Blue
Tits are not a very common breeder in Øygarden, there are a
few
pairs at some locations but the species is most usual as a visitor to
bird feeders during the winter and as an irruptive migrant. As with
many irruptive migrants this species prefers to migrate under clear and
calm conditions in late September or October. During such movements
flocks of 40-60 can be seen.
Some visible
migration
locations where the species does not normally
occur lend themselves well to the detection of these movements -
Gullfjell (see link above) is an ideal spot for this.
This species is an excellent opportunist feeder and although normally
at home in woodland they exploit any available food - even heather
moorland and long grass - as amply illustrated during the autumn of
2008 when large flocks were present on the virtually treeless island of
Hernar in Øygarden.

Flock of migrating Blue Tits, Hernar, October 2017
This Blue tit, caught in my garden at Tjeldstø had been
ringed
56 days earlier at Lista in southern Norway. It had moved 293km NNW and
ended up in my garden. It just shows that these autumn Blue tits could
well have come from further south....
