Quite a lot of Jays on the move here in the arable areas of North lincs around Eastoft. I've had about 6 separate parties of between 2 and 5 in the last couple of weeks, some moving North West and some feeding around isolated areas of tree's.

Anyone noticed any movement elsewhere?

I seem to think these are UK birds but I could be wrong......

I've been seeing the odd Jay in various locations for a couple of weeks now where i would not usually see them, mini influx from the continent?, would uk birds move far?

One in a non-Jay place at Garthorpe today, and I’ve noticed a few others wandering about in this area: flying south along the Alkborough-Burton cliff, and two flying west high over fields near Adlingfleet (Yorks) on 22nd September.

A summary of the big 2012 movement will be in the soon-to-emerge Lincolnshire Bird Report, comparing it to that in 1983. Both of those movements began in a small way around the turn of Sept/Oct with larger numbers from 7th-8th October, so it’s worth watching what develops this year.

Where do these Jays come from? There’s a common assumption that they are continental but precious little evidence for it. BTO’s Migration Atlas suggests the paucity of foreign ringing recoveries may be because so few are ringed in northern areas where they are most eruptive. But you might think that some would have been ringed en route further south in southern Scandinavia or the low countries. Yet there is only one recovery in either direction, and that involved a bird ringed at Dungeness (scarcely in Britain anyway!) in October and found dead in the Netherlands the following June. In the 1983 movement, there were hundreds roaming the Cornish cliffs but not one reached the Scilly Isles, suggesting they were not that keen to cross water – odd for birds supposed to have crossed the North Sea. I’m not saying that none comes from the continent, but think it’s more likely most are British.

I've noticed some movement in the past week and, unusually, had two separately in my garden at Woodhall on 29 & 30 Sept. My last garden records were during the 2012 movement (irruption?). Further to Andrew's comment I have some recollection of seeing jays arrive on the North Sea coast in autumn, but can't provide verification now as to where and when.

Yes, I should have mentioned that ... but the numbers that are seen arriving off the sea are usually small. However, I have seen a count of over 100 for east Norfolk in 1983, and it's also true that presence/absence of coastal sightings of eruptive species don't necessarily prove anything: how often are flocks of Waxwings seen arriving off the sea? But with 32 Britsh & Irish ringing recoveries on the continent, and 55 foreign-ringed recoveries in B & I, there is other evidence for waxwings being of continental origin (as well as the possibly significant fact that they don't breed here!).

More Jays on the move today with obvious parties of 3 and 4 flying high and coming in from Lincs over the reserve at Blacktoft. Also 5 birds seen at the weekend flying over Eastoft and 1 at Luddington in roadside trees.

At least 8 over and around Cleethorpes country park on sunday, first on the patch since the 2012 'irruption'.
