DR. GHALI And have they not regarded the birds above them outstretching (Or: in ranks) (their wings), and contracting (Or: spreading “or” folding their wings) (them)? In no way can anyone hold them except The All-Merciful; surely He is Ever-Beholding everything.

Tafsir of Surah Mulk Ayat 19 – By Abul Ala Maududi
(67:19) Have they not seen birds above them spreading and closing their wings, with none holding them except the Merciful One?  He oversees everything. 
29. That is, each bird that flies in the air, does so in the protection of the All-Merciful God. He it is Who has given to each bird the form and structure by which it became able to fly. He it is Who has taught each bird the method to fly. He it is Who has made the air obey the laws by which it became possible for the heavier than air bodies to fly in it, and He it is Who upholds every bird in the air, otherwise the moment Allah withdraws His protection from it, it drops to the ground.
30. That is, this is not confined only to birds, but whatever exists in the world, exists because of Allah’s keeping and guardianship. He alone provides the means necessary for the existence of everything, and He alone keeps watch that everything created by Him is provided with the necessities of life.
