It would seem that this funeral system that the birds are implementing is very similar to the one elephants do so, there is a possibility that these birds may also have an emotional system. Of course, it still serves a purpose for protecting themselves and others but it would seem that is not what it's all about entirely.
In this thread by smyleegrl: Animals Are As With-it as Humans (Animals Are Conscious) they are coming to the conclusion that animals have a similar consciousness to humans, perhaps they have a similar emotional system and are empathetic/sympathetic. I'm sure most of you will agree that domestic pets can feel when you're upset but maybe it's not limited to them. =)
