Corvids could save forests from the effects of climate change

• arclein

Corvids, a family of birds that includes crows, ravens, jays, magpies, and nutcrackers, are called scatter-hoarders. They roam large territories to scavenge seeds, fruit, and even meat, storing as many morsels as possible to eat later. That's the "hoard" part. But they don't have one giant stash full of loot the way squirrels do. Instead, they hide each treat in a separate place, occasionally moving it around to prevent other animals from finding it. That's the "scatter" part. Corvids are incredibly intelligent, with excellent visual memory, and scrub jays can remember up to 200 different cache locations at any given time.
