Latest Science Bulletins: Cuckoos

Have you heard of brood parasitism? Basically, a bird, a cuckoo in this case, lays its own egg in another bird’s nest and leaves it there for the other bird to raise its young, which it does because the cuckoo baby can sound like, look like, or mimic the mouth markings of the host bird. How does the host bird fight back? Perhaps by recognizing the cuckoo egg pattern and kicking it out of the nest. Check out out bulletin and the below picture of the wonder that is brood parasitism!
