What is the relationship between the pinyon tree and the Jay?
The relationship between the pinyon and the jay is much more than just a food source. The tree produces cones that, when open, provide the jays easy access to the large seeds. And the jays have stout beaks that are specialized for extracting nuts from even unopened cones.
How does a pinyon jay know what seeds to pick?
A pinyon jay can discern by color or weight between a viable nut and one that did not mature through the embryonic cycle. If the seed’s thin shell coats are two-toned or if the shell is lightweight, the jays discard the duds and grab the keepers with their stout beaks. The birds gorge themselves, but also store seeds in their crops.
