Lost Dove

Hello,

For the past 4 weeks, a dove has been landing in our back garden during the evening in search of food. We have been feeding him Brazil nuts, pecans and wild bird seed. During the day, he has been perched on a windowsill for the majority of the day. He is very tame and has a yellow tag on his ankle.

Just looking for some advice on feeding him. Is this normal behaviour for a dove? Any suggestions on how to reunite him with his owner? 

Many thanks,

Emma
