I know they can kick pretty hard and interrupt taming so try to tame the swoop which i think are on the north side of Bloodhoof village only and if possible whatever one is the lowest level , stand as far away as possible and i found if you get knocked over get up and try again as fast as possible as they seem to only interrupt you once per fight , it may help if a priest gives you a stamina buff and the idea of that sticky glue quest Lady isyris said about may give you those few extra seconds you need , but i did it easily enough first time and i guess there would be lots of complaints here if it was as bad as it seems although i cannot remember any threads about it , so as has been said keep trying and you will get it in the end.
