Question

Quizplus · Accepted Answer

Modern birds typically have wings, but not all have a long feathered tail as part of their adaptation. The tail length and structure vary widely among different bird species, and a long feathered tail is not a universal adaptation among modern birds. Adaptations such as a one-way respiratory system, a fully divided heart, endothermy, and modified beaks and feet are more universally characteristic of birds.
