The Beast Sense and Beast Bond spells, as their names imply, require the target to be of type "beast."
Now looking to the Conjure Animals spell, its description says:
You summon fey spirits that take the form of beasts
which makes it sound like they might simply be fey and not really beasts. But then the description goes on to say, of the animals in question:
Each beast is also considered fey
which makes it sound like each animal is first of all beast, and then supplementally "also" a fey.
So which is it? Can Beast Sense and Beast Bond work on these creatures, or not?
