That is one of the most fun you can have. You learn about spotting the difference between a passage and a haggard bird.
Watching a bird sitting and thinking about your trap and then fly down to it will get your heart going.
I am still of the opinion that all apprentices should have to trap their first bird.
On the bad side, there is the cost of gas. On years when vole populations peak, its almost impossible to get a bird to hit a BC when it has a crop the size of a baseball.
