On the ground, it hops, turning head back and forth, because it harvests seeds. As with different members of the Corvidae family, Clark’s nutcrackers are extraordinarily intelligent.

Studies have been carried out on their extremely developed spatial reminiscence associated with meal caching and retrieval skills.

Family teams be a part of collectively after the younger have fledged to kind unfastened flocks. Nutcrackers usually forage harmoniously with different species of birds as nicely.

They use their sturdy pointed bills to pry seeds out of unripe cones or to hammer and crush seeds out of their shells. Then they’ll both eat the seeds or place them of their sublingual pouches for caching later.

Ponderosa seeds are their most vital meals by quantity however seed use adjustments with annual variations in seed availability. Seeds are cached at various elevations, with every cache averaging three to 4 seeds.

A single particular person might have hundreds of caches. Seed shops are recovered utilizing visible cues and spatial reminiscence as much as 9 months after being cached.
