Rooks, crows and jackdaws are the most commonly seen and easily identified ‘crows’. They’re all black and they are widespread across the UK. But they’re not the only members of the crow or ‘Corvid‘ family. Ravens and choughs are also black members of the crow family, although the chough has bright red beak and legs, but both these species are fairly uncommon and seen mostly at or near the coast. There are two common and more colourful crows, the magpie (Pica pica, Dansk: husskade) and the jay (Garrulus glandarius, Dansk: skovskade).
Magpies can be seen everywhere, this one was in a tree opposite my garden
Magpies have an unfortunate reputation on two counts. They are considered to be inveterate thieves, having a particular fondness for shiny objects and they are generally reviled for their feeding habits during nesting of raiding other birds nests and predating the chicks. Of which more in another post. It seems to me they are handsome birds which are much maligned, they simply do what all wild creatures do, i.e. whatever is required to survive and propagate the species. While I watched this one I could hear several green woodpeckers (Picus viridis, Dansk: grønspætte) yaffling around the field and eventually one chased this magpie away from the top of the tree:
The woodpecker, bottom left, was extremely unhappy with the presence of the magpie and voiced it’s discontent with lots of shrieking as it flew aggressively into the tree
Jays are less frequently observed than magpies, predominantly dwelling in wooded areas in the countryside, but they are also seen in towns and villages where there are wooded areas. I’ve seen them along the Backs in Cambridge, and my friend who lives in a less wooded part of Cambridge has photographed them in his back garden. I encounter the occasional jay brightening up the day when I’m out walking around Histon, but last Sunday I had eight sightings, which is completely unprecedented. There were at least five individuals, one pair appeared together in the fields followed by a separate one a few seconds later, and another pair were busy burying acorns in the orchard opposite my garden. And they are spectacularly colourful, not at all what one might expect from a crow:
The splendid plumage of the jay!
Several jays and magpies came and went from this spot at the top of the tree in the space of a few minutes.
And when in flight the electric blue flash on the wing-bend opens up into a fan
As well as having an eye for sparkly trinkets jays are accomplished stashers and hoarders, and I’ve heard that a single jay can stash as many as 5000 acorns. They also show higher levels of intelligence whilst stashing, if they become aware they are being watched they will pretend to stash and then move away and hide their acorn somewhere else. I think that’s remarkable behaviour; moving away and hiding food elsewhere is one thing, but awareness of what another creatures intentions may be, and reacting to that by subterfuge suggests a level of underdstanding and reasoning not commonly associated with creatures other than humans.
On the ground with an acorn in its beak looking for a suitable burial site, and checking its handywork :
As I watched this pair of jays at work, one of them put it’s acorn down and picked up a short stick, probably around 10cm long, and used it to make holes to bury the acorns in. So as well as the other tricks this jay used a tool to make bigger holes in the ground than it could manage with it’s beak in order to secrete its winter food supplies.
They’re remarkable birds, the Corvid family, and half an hour spent watching any crow species is entertaining and more than a little thought provoking.
