The tiers
Every owl you burn makes one owl stronger
When you burn, you nominate one owl you are keeping. All the weight from the burned owls moves into it, plus a bonus. That owl climbs the tiers and earns like the pile it replaced.

Weight is a pure function of what an owl has absorbed. An owl that has taken in N others carries 1 + N + 0.25N + N squared over 400. That last term is what rewards concentration: it grows faster than the burns themselves, so pouring everything into one bird always beats spreading the same burns over several.
Concentration always wins, and that is provable. Split 108 burns across two owls, 10 into one and 98 into the other, and you hold 161.26 weight between them. Pour all 109 into a single bird instead and it carries 166.95 on its own. Same burns, more weight, and one owl that outranks anything the splitter holds.
Merging tiered owls loses nothing. Every point of both carries across. A Ghost burned into a Raider brings its full weight with it, whatever the order, whatever the sizes. The only number that ever moves in the collection total is the bonus.
And it cannot be farmed. Weight depends only on how many owls a bird has absorbed in total, never on the order of the burns or how many transactions you split them across. There is no loop that manufactures weight.
