Fellow bird researcher Mohamed Amezian, who details the findings on his blog, told MailOnline: ‘Many animals such as falcons – Eleonora’s and Sooty falcons – and different shrikes (Lanius spp.) are known to store dead prey in places known as ‘larders’, but storing live prey has never been observed in any bird species.’
The authors report that the behaviour was seen among the falcons before their chicks hatched, perhaps to allow them to stock up before the hungry mouths of their young appear in the nest.
They write: ‘Keeping prey alive, one or two days (the precise period not yet known), may allow the falcon to have a fresh food on the right moment, because the dead prey brought to the nest and untouched can no longer be consumed as it dries out too quickly.
