The plight of a less fortunate creature

Bird of paradise, in all your splendor
Flying through the twilit skies,
Experience the joys of freedom on a first term basis,
But be warned that these are just convenient lies
You return to your humble abode,
The one that you yourself had made
Only to discover it smashed and burned
For lo! Has descended the angel from Hades
You take refuge on a nearby branch
And scope out the new creature you see,
In size much bigger than you, though doesn't fly,
And shows no regret for it's deed
Soon enough, it is joined by another,
And they, together,
Also tear down the house of your little brother
You watch helpless, for you know not what to do,
Watch your world fall apart, right in front of you
You wonder in anguish if you are being punished,
For some sin you now forget
But fret not
And stress not your little avian mind,
For it's just the result of being in mother nature's debt
You take to flight yet again,
To search for a new home this time,
Flying through the now moonlit skies, you know how free you are,
'Survival of the fittest', unfortunately for you,
Is the name of life's malicious rhyme
