Meaning of BIRDS

They are used as symbols of agents of evil (cp. Gen. 40:17); In the parable of the Sower, the birds that devoured the seed by the roadside are interpreted by Christ as "the Evil One" (Mt. 13:4, 19).

In the parable of the Mustard Seed, the kingdom of heaven becomes a great system with roots in the earth, under whose protection the birds find refuge (Mt. 13:31, 32). The Greek word is the same in both passages.

In the OT we have two lists of impure birds (Lev. 13:20; Deut. 14:12-18): The eagle, the bearded vulture, the goshawk, the buzzard, the kite, the crows, the ostrich, the owl, the gull, hawk, owl, grebe, ibis, swarm, pelican, vulture, stork, heron, hoopoe and bat (the Hebrew classification of birds was "functional"; they classified everything as birds the flying

Since classification is an activity based on criteria that can be established arbitrarily, it cannot be considered an error at all, but only as a classification based on a different criterion to which we are accustomed).
