One of the lads at work is getting a Swedish Goshawk this week and getting rid of his other birds (he says it makes his Harris Hawk and other birds seem like a butterfly in comparison).
I was talking to him this morning and he was saying that unlike his Harris Hawk he actually wants the Swedish Goshawk to "imprint" with him.
That way it kind of sees him as its partner? and stays with him.
Aparently if you do that with a Harris Hawk they squawk too much.
{edit, he just went to see one this week but won't be getting one for a month or two}
