With tiny [...], the bird scanned its vicinity, completely ignoring me.
I thought of the word hoppings but sounds strange and it only has 1 Google result.
Is there a better option?
Hops. There is a noun sense of hop that means such a tiny jump.
That said, I like "with tiny hoppings" better. It's a reasonable use of the gerund and the sound matches the imagery well but without being so overly poetic as to distract. Hops would be more usual, but hoppings is more vivid in this particular case.
If you're looking for something a little different, try the noun form of flit.
flit n A fluttering or darting movement.
This adds the sense of using the wings a little, but is not overused like some of the others. You can even blend it with another idiom to make something small and fidgety:
The tiny bird moved in flits and starts.
