Sure, I just think it's interesting, and that surely you do need to think about why you're interested in whether an animal 'makes' or uses 'tools' to know where that cut-off should be, otherwise it's a bit arbitrary and self-fulfilling ('only humans and some apes use tools' ... 'where tool is defined as a manufactured object held in the hand'!) isn't it?

IIRC, Bees build their hives with their own secretions. I see this as categorically different than animals that make nests out of various items laying around. In the case of a beaver I think it is more advanced than a birds nest because they actually harvest specific trees instead of using what’s on the ground already.
