Where have our Jackdaws gone?

[hungerdunger]

This year we have had at least three pairs of Jackdaws nesting in our outbuildings. All the offspring have fledged and every day they've been eating from our bird feeders and generally making a lot of noise.

This morning it seemed very quiet outside and we suddenly realised that all the jackdaws had gone - there hasn't been a single one all day.

Can anyone confirm that this is normal jackdaw behaviour, and if it is, where have they all gone? Do they migrate between different parts of the country?

(If it helps, we live in West Wales (Carmarthenshire))

They may well be on holiday here in Lincolnshire, we've had 9 comming into the garden the last few days harassing the smaller birds on the various feeders and as much as I love their comical antics, they along with the crows and magpies are a real pain at the moment maybe because there's so many babies about for them to pick from
