Jackdaws are smaller than Crows and have a mostly grey head with a black cap, a dark grey front and distinctive light/white eyes.
Often seen in pairs, they have a strong pair-bond.
Those in the UK/Europe through to mid-Russia/Central Asia are also called the Western or
Eurasian Jackdaw, to distinguish from the Daurian Jackdaw in the Far East.
They are gregarious birds which spend much of their time high in trees or on high buildings. They often nest high on churches,
cathedrals and similar; also on cliffs. Above right is a juvenile.
Jackdaws on garden feeders. The flock ("clattering") has a strong social hierarchy.
Jackdaws will occasionally carry off and hoard shiny material/objects, as magpies do.
More Jackdaws on garden feeders - they've learnt from the other birds, but they don't always get their own way.
Above centre has a rufous undertail and others (further above right and centre below) have patches of rufous plumage.
There are four subspecies of Eurasian Jackdaw over its range, most here being C. m. spermologus
in the UK and most of Western and Central Europe. Above left with a partial white collar is C. m. soemmerringii, which
covers northeast Europe, Western Russia, Turkey through to Central Asia as far as Mongolia and north India. The nominal subspecies covers Scandinavia and
Eastern Europe.
