those are actually frequently initiated even while predators, such as coyotes, are visibly present. And the jump yip operates as a highly contagious social display propagating through the colony in a wave like Cascades similar to contagious yawning in humans. And it's theorized that the behavior functions as an active social probe and it's used to assess the vigilance of neighboring colony members. So if a jump yip initiates a strong prolonged wave of reciprocal responses from neighbors, the instigating prairie dog reduces, or excuse me, deduces that the colony is collectively alert. And once they're satisfied with the shared vigilance, the initiator subsequently reduces its own defense of scanning and decides that it can go back to foraging for food or whatever because everybody's equally alert. So you drop it.
