Can animals have accents?

People who speak the same language but grow up in different locations can develop accents. Can the same thing happen to animals too? If so, could two animals of the same species with different accents communicate?

Orca (killer whale) groups have different dialects based on their family groups. The northern resident group of orcas (found off the coast of British Columbia) has been divided into three different clans, A, G, and R, based on their vocalizations.

Transients (now also known as Bigg's killer whales) live in much smaller social groupings. Their ranges are larger, and their calls are distinctive from other orca populations, but are similar to other transients all along the Pacific coast.

In captivity, they have been able to learn the calls of orcas from other groups. The Vancouver Aquarium had a female named Skana, from the Southern Resident population. A male, Hyak, from the Northern Resident population, learned her calls. After Skana died, the aquarium acquired two orcas from Iceland. Bjossa learned Hyak's calls and even some of Skana's, despite not having met her.
