Feathers

FEATHERS

They insulate from water and insulate from weather
A very complex integumentary structure is the feather

They may also be plucked to line the nest
And keep birds warm from tail to breast

Skeleton or plumage, what’s heavier, whether
You might be surprised the answer is feathers

They form a helpful covering
And help the bird’s mothering

Rarely are there feathers on legs
But they help the birds protect their eggs
