Quibus avibus sanctus Franciscus ait: 
 “Multum tenemini Deo, sorores meas aves, et debetis eum semper et ubique laudare propter liberum quem ubique habetis volatum, propter vestitum duplicatum et triplicatum, propter habitum pictum et ornatum, propter victum sine vestro labore paratum, propter cantum a Creatore vobis intimatum, propter numerum ex Dei benedictione multiplicatum, propter semen vestrum a Deo in area reservatum, propter elementum aeris vobis deputatum. 
 Vos non seminatis neque metitis, et Deus vos pascit; et dedit vobis flumina et fontes ad potandum, montes et colles, saxa et ibices ad refugium, et arbores altes ad nidificandum; et quum nec filare nec texere sciatis, praebet tam vobis quam vestris filiis necessarium indumentum. 
 Unde multum diligit vos Creator qui tot beneficia contulit.  Quapropter cavete, sorores mes aviculae, ni sitis ingratae sed semper laudare Deum studete.”

...  He departed thence and came between
 Cannara and Bevagna; and near the road he saw some trees on which perched so great a number of birds as never in those parts had been seen the like.  Also in the field beyond, near these same trees, a very great multitude rested on the ground.  This multitude, Saint
 Francis seeing with wonder, the spirit of God descending on him he said to his companions: 
 “Wait for me on the road, while I go and preach to our sisters the little birds.”  And he went into the field where the birds were on the ground.  And as soon as he began to preach, all the birds in the trees came down to him and with those in the field stood quite still, even when he went among them touching many with his robe.  Not one of them moved, as Brother James of Massa related, a saintly man who had the whole story from the mouth of Brother Masseo who was one of those then with the sainted father.

To these birds, Saint Francis said:  “Much are you bound to God, birds, my sisters, and everywhere and always must you praise him for the free flight you everywhere have; for the double and triple covering; for the painted and decorated robe; for the food prepared without your labour; for the song taught you by the
 Creator; for your number multiplied by God’s blessing; for your seed preserved by God in the ark; for the element of air allotted to you. 
 You neither sow nor reap, and God feeds you; and has given you rivers and springs to drink at, mountains and hills, rocks and wild goats for refuge, and high trees for nesting; and though you know neither how to spin nor to weave, He gives both you and your children all the garments you need.  Whence much must the Creator love you, Who confers so many blessings.  Therefore take care, my small bird sisters, never to be ungrateful, but always strive to praise God.”
