"In many cases there are "smart" ways to deal with these troubles. As a teen back in the 70's I could leave my pigeons out all day long. For years growing up in the St. Louis Metro area I rarely even saw a hawk much less had an attack. Having rejoined the sport in the early 2000's, I can hardly believe the that Coopers hawks of all hawks are so plentiful and that they are so efficient at what they do. In my area Goshawks are a rare winter visitor and now I truly pity the fanciers that live in areas where the Goshawk lives year round. The Coopers does not always make a kill, in fact only about 10% of the time here in MO. However, when the Goshawk attacks, so far their kill ratio has been 100 %.
