Fickle them all

The fledgling flees the nest and flies,
The starling raps its head and dies,
The cuckoo feigns to lay the nest,
The chick thus shrieks to egg's unrest.
The magpie steals its silver loot,
The dolllar's one and two's the coot,
The Moorhen rifles through the reeds,
The bittern hides from bitter breeze.
The heron stands, upright and tall,
The swan is fickle, fickle them all.

Homeostasis

I don't feel warm,
I don't feel cold.
I just am.

Just to be is just to be,
The freezing winds,
The sunny beach.

My coat is warm,
My goosebumps prickle
But life is long
While seasons are fickle.

The worm

Immersed when it's sunny
And surfaced under weather,
The tunnels always twist and turn.

The softened segments never change
As the earthworm crawls,
Sometimes it contracts but then it sprawls.
