This strikes me as the key reason to build nests in inaccessible places
reachable only via specialized anatomical adaptations. It's an aspect of the
escape-from-predation problem I hadn't previously considered. And cliffs or
trees serve pretty much the same function in BCF, even though I use
"arboreal," I could equally well use "cliff-dwelling" or some high-falutin'
word that simply means dwelling in high places, like "acronomic." Hey, that's
pretty good...
