ive bred and flown spars,there main game is magpie jackdaw piegeon crow and most of the corvid family,i used to fly my female at most of these and black bird are good sport,the male in my oppinion is harder to fly but is very agile at going through trees then the female but the female will take on bigger prey then the male ,bothe of these birds are no good for a novice and are easy to kill in the wrong hands ,they suffer from fits and bad antics at times but once you have them flying are a awsome bird to use hope this helps
