black bird throws mulch (bark chips) etc

I want to describe what I see.

The Black bird throws the mulch (bark chips) out of the garden onto the footpath (=sidewalk) and the road while looking for bugs and worms. Then I have to clean it up.

So how could I describe this in Latin?

Merula bēstiās et vermiculōs quaerento, fragmenta corticis ex horto in viam iacit.

maybe even
Necesse est mihi fragmenta corticis quae Merula bēstiās et vermiculōs, quaerento, ex horto in viam iacit, purgare..

Any improvements welcome.
Thank you

Quick points:
By quaerento you mean quaerendo? But what you want is quaerens.

bestias suggests big wild beasts, the kind you feed Christians to. Try another diminutive, bestiolas.

For your concluding sentence start a new sentence. E.g. dein mi necessest …

Thank you. So now
Merula bestiolas et vermiculos quaerens, fragmenta corticis ex horto in viam iacit. Dein mihi necesse est viam purgare.
