We have creeper growing over our house.
Every year we have several pairs of house sparrows nest in it successfully.
Yesterday, there was a commotion and several sparrows emerged from the ivy, fighting in the air.
They were pecking and harrassing one particular male, who then fell to the ground – stone dead. I have never seen such behaviour before.
Thank you Lincoln Birder. Amazing. We see a flock of sparrows every day. They are tree sparrows though. These sparrows spend ages on the grass together pecking at the bird food and some open soil that I have near the feeders. I still find it hard to realise that birds do kill birds. I know robins fight to the death sometimes, but watching robins it is hard to believe that as well.
Thank you for sharing this with us.
Here is a report from 1912 about sparrows evicting a martin from its nest. But in this case the sparrows met a grizzly ending
