Disputing the notion that the deaths of animals are insignificant or interchangeable, Discovery News writes that birds gather in vigil by their dead and join together in song:
Researchers have just observed what appears to be the avian version of a funeral. Teresa Iglesias and colleagues studied the western scrub jay and discovered that when one bird dies, the others do not just ignore the body. Multiple jays often fly down to gather around the deceased.
The subsequent ceremony isn’t quiet either. “Discovery of a dead conspecific elicits vocalizations that are effective at attracting conspecifics, which then also vocalize, thereby resulting in a cacophonous aggregation,” Iglesias and her team wrote.
Prior research suggests giraffes and elephants might also hold ceremonies for their dead. If so, perhaps there are shared factors with humans and birds. Solidifying group togetherness and social bonding appear to be key benefits, along with learning how to avoid (if possible) whatever did in the deceased.
