All the Apples will soon be gone

Watching the Feildfairs in my garden today,being confronted by my regular garden birds,was the best entertainment in ages.
  Blackbirds at first were not too sure.But I have  pairs so for once the had a common enemy?And did they ever gang up on the Feildfairs?
 Many of the Feildfairs fought among themselves!
They are very attractive birds all the same?
   They will probably be here tomorrow? But with normal weather on its way.They will be off back to cooler climes again?
