Magpies stand accused of many crimes including thievery and murder. Yes, they do carry out acts that may be considered as nasty one of which is the killer of baby birds. However, this, it turns out, usually takes place when they are in breeding season and have babies of their own to feed.
Most of the year they are vegetarians so, in fact, it's not out of choice that the crime of murder is carried out. They do so to make sure that their own brood survives. Okay, it could be argued that there is an alternative to killing baby birds but Magpies are not stealth hunters and they do not even possess great speed. They, therefore, have to find easier ways to feed their own babies. Also, they will scavenge.
It turns out that the decline of Britain's songbirds are not connected to Magpies whatsoever. So, they are innocent of this crime.
