Animals often form friendships with each other (and even with other species). Horses have favorite equine companions in the pasture, and cows and goats have similar associations. Dogs have canine buddies, cats have feline chums, and both birds and fish are known to form favored associations with other individuals.

Plants disperse their seeds in many ways. Some cast their seeds into breezes or water currents, some produce seeds with adaptations that facilitate transport on (or in) animals, and so on.

They’re fun to watch — always active, leading mixed species flocks in fall, sometimes storing seeds for hard times to come.
