I think the Maewing has been somewhat nerfed lately, it's rated 3.9 for Berry gathering on here yet its AOE for gathering from bushes is incredibly poor, I've tried with 2 now and both of them need you to get directly on top of a single Bush to gather from it and even then sometimes it doesn't work, I found I was faster gathering berries by hand...

For breeding however these things are incredibly useful for raising babies in bulk as they have the ability to act as a feeding trough for babies until they reach juvenile and can access a normal feeding trough.
