Debunking myths about magpies
This handsome bird is often unfairly blamed for wider changes in the British countryside, but is far from invulnerable.
The magpie has the worst reputation of any British bird. But, says Derek Niemann, the case against our piebald corvid is far from black and white.
Here, he puts the worst rumours to the test to decide on a final verdict: guilty or not guilty?
Gangland bully?
- Do magpies use strength in numbers to bully weaker creatures? During the hour before darkness falls, magpies gather in groups – often of 20 or more. But the purpose is quite innocuous: they are coming to roost.
- And the small gangs that taunt a cat, fox or stoat are using self-defence, trying to drive a predator away. There have been no known cases of magpies using mob-handed bullying tactics.
Verdict: Not guilty
Crimes against music?
- Angered geese trumpet with higher decibels, but urban magpies have more neighbours to disturb with their rattling fusillades. The best that can be said of their clacking is that it is ‘percussive’.
- But get close enough in spring to see the scarlet tongue lifting in a male’s part-opened bill and you might hear it sing a soft lullaby meant for its special other.
Verdict: Not guilty
Cause of songbird decline?
- British Trust for Ornithology research (2010) combined data from 200 sites in 1967–2000 with information collected by 2,000 volunteers in 1995–2005.
- It showed that there was no causal link between an increase in magpie numbers and a decline in songbird numbers.
Verdict: Not guilty
Killer of baby birds?
- For eight months of the year the magpie subsists on a largely vegetarian diet. But in the breeding season this alert opportunist has five or six hungry young to feed.
- It doesn’t hesitate to take the eggs and chicks of other birds to sustain its own brood.
Verdict: Guilty
Thief of shiny things?
- This persistent myth has been perpetuated in the arts, including in Rossini’s opera La Gazza Ladra (The Thieving Magpie).
- Though captive magpies do learn to pick up the bright trinkets they notice that their owners value, there is no evidence of such behaviour in the wild.
Verdict: Not guilty
Did you know?
Urban magpies are pooper-scoopers par excellence. A study in Sheffield found that up to a sixth of the corvids’ food hoards were dog faeces: they can extract nutrients from the ordure.

MAGPIES
Hi Derek
re, There have been no known cases of magpies using mob-handed bullying tactics.
Verdict: Not guilty
i asure you magpies/jays do use bullying tactics on weaker birds to pinch food off them,i guess people are not studying them long enough unless you live with wildlife every day for years you miss a lot of behaviour.
i spent years living with sparrowhawks,as soon as the juvanile spars leave the nest,magpies/jays sit in gangs waiting for the sparrowhawk parents to drop off food for them,as soon as the parents leave they move in to pinch the juvanile spars food in gangs the juvanile spars are not powerful enough at 4 weeks old to fight back.
jays even start to mimic the juv sparrowhawks so the parents drop close to them,as soon as juvanile spars are 6 week old they then practise there hunting skills on magpies/jays.
predation by magpies eg, songbird nests 30 percent are predated by magpies when hawks nest in the copse,when hawks fail to nest it rises to 80 percent predation even forcing songbirds away to nest else where.
so when hawks nest here they help keep corvids away from the copse so more broods of songbird are raised when hawks are here.
sparrowhawks dont kill around the nest site from mid march-end july so songbirds have protection from the hawks in these months raising succesful broods.
most years 3 broods are raised by songbirds,1 is lost to the juvanile sparrowhawks when learning hunting skills in august.
and 1 to corvids, and 1 survives keeping the balance just right,when no hawks here magpies predating nests of 1st and 2nd cluth means the song birds lay fewer and fewer eggs so less songbirds in that year.
