I want to know the answer to the following question:
What is kleptoparasitism?
All the background I'm provided with is that "Kleptoparasitism is thought to be a supplement to food obtained by hunting, rather than a significant part of any species' diet; a study of great frigatebirds stealing from masked boobies estimated that the frigatebirds stole at most 40% of their food and on average stole only 5%.". Is that enough to answer the question?
