The behaviour is well known. As to why, well maybe it has been evolutionarily advantageous for them to be aggressive to all birds of all species, without any distinction as to whether or not they are a predator or competitor. It saves effort or mental ability on them being capable of discriminating, which may be a skill they have not yet developed. Sometimes the aggression may be greater than at other times, leading to this extreme as described here. Philip |
