African painted-dogs have a keen sense of hearing. Their ears are shaped like parabolas so they collect sound efficiently. Each ear can be pointed in a different direction so the dogs can be checking for sounds all around them. They also communicate with barks. The entire pack was near us, some lying down, and some milling around. Then the birds started making lots of noise. The dogs all perked up. Suddenly, one of the dogs gave kind of a yelp and within seconds they cleared the area on a full run. Within less than a minute the lions walked into the area. We were lucky to see this interaction.
Izzie, here is a Black-backed jackal just for comparison.
