Nice sharp shot Silver;

what camera are you using?
black oil sunflower and safflower is good mix, cardinals love it also; where are you deep south ? I don't see this kind of birds here around Great Lakes; I keep feeder only in winter time;
Cooper's hawk , last weekend around feeder, this sexy beast is great skilled hunter, picks easy the noobs songbirds; I shoot with Panasonic camcorder in photo mode, the longest dslr lens I have is 250mm;`
