Hi everyone! ❤️ One of my baby magpies (around 2 months old) seems to have lost his voice over the past three days. He used to beg loudly, but now only a faint, scratchy sound comes out despite trying to call. Otherwise, he’s completely healthylooking, active, eating and breathing normally.
What could be causing it, and should I be worried?

a pair of magpies regularly visits my garden, but this autumn a third bird started showing up. the original two get loud and chase it away, while the newcomer keeps its distance and comes back anyway

i've occasionally given the pair small bits of plain beef, so i'll stop for a while to see if food is part of the problem

has anyone seen a newcomer eventually get accepted by an established pair, or do these disputes usually end with one bird moving on?
