Final answer:
The Great-crested flycatcher is categorized as a bird, which is known for characteristics like feathers, the ability to lay hard-shelled eggs, and flight.
Step-by-step explanation:
The Great-crested flycatcher is an example of a species from the bird category. Hence, the correct answer is b) Birds. Birds are a group of endothermic vertebrates characterized by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. The Great-crested flycatcher, known scientifically as Myiarchus crinitus, is a member of the avian family Tyrannidae. Birds, like reptiles, have similar circulatory and excretory systems and both are egg-laying animals. However, birds have evolved characteristics such as wings and feathers that are distinct and allow for flight, although the wings of birds and butterflies have similar characteristics for flight despite not sharing an evolutionary relationship.
