From a slow-moving train I saw a fox standing with its tail resting on the ground while two magpies repeatedly took turns to peck the tip of the tail, before running off. The fox merely flicked its tail each time. What were they all doing?Sue Murdochs, Marton cum Grafton, North Yorkshire, UK
Was this at the time of year when magpies build nests? In spring, I sometimes see crows creep up on my neighbour's sheep when they are lying down, so they can pull beakfuls of wool out. The poor sheep hate it.
When I was a kid my parents took us camping. We clambered out of the tent one morning and had breakfast. While I was eating a bird swooped down and grabbed some of my hair and took off. I'm sure it was risking it all for nest building material. Or perhaps he had a thing for blondes!
Recently, looking out of our 4th floor window overlooking a public park I saw a crow trying to harass a cat lying on the grass near some trees, by pecking at the tip of its tail. The cat would move around to face the crow which would then hop around and peck the tail tip again. This went on for some time and didn't really seem to bother the cat. Finally I tired of watching the stalemate and left them at it. Several years ago in Jerusalem anyone trying to walk along a stretch of pavement near a tree in a certain street was divebombed by crows. At the time the TV news showed clips of people trying to run the gauntlet. Some used a umbrellas. Unfortunately I do not remember the seasons of these incidents. I think it more than likely that all these incidents, including the magpies (also an aggressive bird), involved defense of nestlings in a nearby tree.
The magpies were probably defending a nest. A similar event was shown on America's Funniest Videos with a cat the target. It just wasn't bothered enough to retaliate or even turn around. The bird kept pouncing while the cat just lay there apparently unconcerned. This went on for several minutes.
I've had a magpie nest in my garden for two years. Every spring, when the babies are born, both parents harass my two cats who cannot approach the tree, and sometimes can hardly get out of the house. These magpies are quite fearless, hunting down my cats right up to my doorstep, and keep up a loud and disagreable chatter. It usually lasts about a month or so, but sometimes can happen in autumn or winter, even though the nest is empty. My magpies seem to only attack potential predators by pairs, but many members of the crow family are known to band up against predators. I've seen several times a flock of crows attacking a buzzard or a sleeping owl.
