Before we go tonight... more on that research we mentioned earlier from Cambridge University that shows corvids, including crows and magpies, are more likely to show fear in relation to unfamiliar objects than other birds.
But researchers also found the birds were less fearful if the objects involved were similar to something they may have encountered before - so those living in urban areas were less hesitant in approaching litter than their rural neighbours.
Alison Gregor, who led the study says: "In future, others might be able to use this information to predict what types of things animals need to learn to be able to survive in urban areas."
Now there's food for thought as you perhaps think about supper. Thanks for your company today, we'll be back from 08:00 on Thursday.
