"Every creature prays"

Salaam Halila

"All the angels pray. Every creature prays. Cattle and wild beasts pray and bend the knee. As they emerge [(egredientes)] from their barns and caves they look up to heaven and call out, lifting up their spirit in their own fashion. At that time the birds too [(Sed et . . . tunc)] rise and lift themselves up to heaven: they unfold a cross of wings instead of hands [(alarum crucem pro manibus expandunt)], and give voice to what seems to be a prayer."

     Tertullian, On prayer 28-29, modifications on the translation offered by DivineOffice.org (I haven't checked the Liturgy of the hours) mine.  (These seem worth noting because the effect is to capture the creatures at morning prayer specifically.)  From DivineOffice.org:

All the angels pray. Every creature prays. Cattle and wild beasts pray and bend the knee. As they come from their barns and caves they look out to heaven and call out, lifting up their spirit in their own fashion. The birds too rise and lift themselves up to heaven: they open out their wings, instead of hands, in the form of a cross, and give voice to what seems to be a prayer.

Latin from Universalis (=CCL 1, 273-74).
