Through the course of the Spring turkey season the Tom goes through different phases and you need to figure out where he is in the breeding season. From early Spring start the Tom starts gobbling to gather his hens and he is callable. This is the first peak of gobbling as there are several. Later in the season the Tom still gobbles great from the roost but once he flys down in the morning and joins with his hens he shuts up as he is in Strut following his hens most of the day. Later as he breeds and his hens wander off after breeding for the hen to find their special nesting spot the Toms may gobble a bit more and may be a bit more callable. As Spring wears on the hens leave him quicker and he becomes frantic looking for hens so do - he gobbles more. When hens finally are on nest and do not come to the Tom as he gobbles he is really callable and this is sometimes called the second peak of gobbling. That is spring in a nutshell.

So you need to figure what the Tom is doing.
