Concept/Content defining morality / nest parasitism: reed warbler feeds cuckoo chick in its nest
Information caption  
Inquiry caption How do we define scientifically which behaviors are moral? For example, here a reed warlber feeds a cuckoo chick that has parasitized its nest. Was it "wrong" for the cuckoo's parent to lay its egg in the reed warbler's nest? How do we characterize whether this is a moral question or not? Perhaps you can suggest a scientific definition of moral behavior? How do we ensure that any such definition does not express a value judgment or introduce bias?
[Follow-up:] Who studies and conventionally defines morality (in a professional sense)? How might one borrow or make use of their expertise?
Target Concept: Biologists borrow from other disciplines in characterizing behavior as moral.
