Blackbird killing but not eating worms?

This question is answered
Hi all, Has anyone noticed this behaviour before? I saw a big juicy worm on the patio, alive but struggling and thought our Blackbird would be along shortly to enjoy a treat. A few minutes later I saw our male and female Blackbird each with a juicy worm, both pecking at them but the female ate hers and the Blackbird left his and I saw another large dead worm nearby a few minutes later. I'm scratching my head, I can't understand why he'd go to the effort of (as Bear Grylls would say) finding it, catching it and killing it but then leaving it. It reminds me a bit of cat begaviour (sorry cat lovers!) Any thoughts? (Edit: Oops, sorry, I think I've put this in the wrong place, feel free to move it).

  • BamBam is right.   Male Blackbirds don't feed the females as such but will pull up worms for the female to take.   This is his interpretation of courtship feeding.   If he was pulling up a worm for himself and the female appeared, he'd leave it for her.   Generally speaking, males don't feed females on the nest.

  • Maybe there is lots of food in your garden and the young are well fed and the worms you are seeing are worms the male is presenting to the female as a pair bonding thing and she too is well fed so they are leaving them though the urge to forage is still strong.

    I hope someone as a better answer as i'm curious to know now :-)

  • That's interesting and makes sense, thanks both.
