Is it:

Lollypops?

My name sounds like a bird

I can't get this one

Whole body is like tongue of a lizard

It twist like a lizard in sharp

Am different colors

Colorful candy!

And I well can be very littered

Once you're done eating...littering is no good

My energy melts away over time
But not quite like an ice

Sugar melts

And when not taken care of
I'll collect dust and lice

Leave it alone and it'll get dirty
