New Pigeon

[biophiliac]

The only sounds I've ever heard him make are when he's eating and the chickens or tweety birds get too close. It sounds like he is growling at them.
Listen close to this video and you can hear him: https://goo.gl/photos/yfNUvatQdPXvk2ra9

I couldn't hear, sorry.

Sometimes one will be small and delicate looking and it is a male.. other times I have had big birds with lost of colours on their necks, thick heavy set bodies and big heads.. which behave aggressively and even coo and bow and chase other birds.. only for them to turn out to be females!!!

Very interesting! They definitely are fascinating birds.
