With the new additions of speech mechanics and moon- star-watching, could there also be a small thing:
Thrushes(in Erebor only?) and ravens would come around dwarves. Other birds will come around Elves. This doesn't happen too often, but isn't rare. Maybe they would even sit on their shoulders?
P.S. Addition of Thrushes and Ravens will be needed for this. In the elves' case, maybe only seagulls will do it.
