Hello guys,
I make European crow calls in here Belgium as a hobby ( for carrion crows, magpies, hooded crows and jackdaws, not for rooks ). I really feel that my calls generate a much better sound when you compare them to any other commercial crow call on the market and I totally agree with the comments of Ironhorse . Please check out my videos on www.youtube.com, search for "corvussam ".
Here is one video :http://www.youtube.com/watch?v=BvFyTjlQ94c&layer_token=67fca9ac0fee6c87
Thanks,
Sam
