Calendar Periods are not seasonal patterns. A pattern as it’s commonly understood MIGHT be seen to exist within a Calendar Period but patterns are more typical of LM and are very transient, while the Calendar Periods are prime movers of behavior. This concept as it is now expressed by the In Fisherman staff guided my approach to angling hunting and trapping since my Grammy taught me how to produce fish and game for the family at age 10. Here is a nugget of the concept which is the best I can do at the moment as I’m going fishing . Spring dictates that female snapping turtles must leave the ponds to find sand banks of the correct composition and exposure in which to lay their eggs. If you seek out those banks at the appropriate time with a snappers eye you may get turtle eggs (no treat) and turtle stew. Without the calendar period driving the turtles to select those specific banks you will find NADA even if you learn to pick banks like a snapper. Wrong calendar period no snappers on gravel banks. Many smallmouth anglers waste their time angling where it “looks good for smallies” or where they have previously caught smallies without appropriate regard for the Calendar Period. They need to develop the eye of the “turtle” and move in the same rhythms.
