Is this nor­mal bird be­hav­iour?

Bird Watching (UK) - - Your View -

QMy un­cle is a sub­scriber to your mag­a­zine and has asked me to put the fol­low­ing ques­tion to you. He is watch­ing Car­rion Crows or Rooks tak­ing green cones from a Scots Pine and sit­ting on the roof op­po­site ap­pear­ing to eat them? Is this nor­mal be­hav­iour? Joan Gunn

ACorvids are both om­niv­o­rous and in­tel­li­gent, and have been known to ex­ploit many food sources. Car­rion Crows and Rooks have both been known to hunt small mam­mals, scav­enge, and even fish for food. Although we’ve not heard of this par­tic­u­lar be­hav­iour be­fore, var­i­ous corvid species have been re­ported drop­ping fully grown pine cones from height in or­der to ex­tract the seeds to eat, and this could be a de­vel­op­ment of that be­hav­iour.
