where any bird can see it!
The mention of a bird being able to see the net suggests awareness and discernment. In the cultural context of ancient Israel, birds were often used as symbols of freedom and awareness. The idea here is that just as a bird would avoid a visible trap, so should people avoid obvious sinful schemes. This can be connected to the wisdom literature's emphasis on discernment and understanding (Proverbs 2:11-12). The phrase also serves as a warning against underestimating the awareness of others, including God, who is omniscient. In a broader theological sense, it can be seen as a call to live righteously and transparently, knowing that God is aware of all actions and intentions.

(1) I.e. to no purpose, gratis, frustra (Vulgate, Chaldee Paraphrase, Arabic). The meaning of the proverb here used then is, "to no purpose is the net spread before birds," i.e. though they see the net spread before them, they nevertheless fly into it (romp. Proverbs 7:23, "As a bird hasteth to the snare, and knoweth not that it is for his life"). So sinners, when they are plotting for others, plunge into their own destruction with their eyes open. Therefore do not associate with them, do not imitate their crass folly, be warned by their example, or you will share their fate. This view is supported by the LXX. reading, Οὐ γὰρ ἀδίκως ἐκτείνεται δίκτυα πτερωτοῖς, "For not unreasonably is the net spread before birds;" i.e. they fall into the snare (see Luther, Patrick, Umbreit, Ewatd, Hitzig, Zockler, Plumptre).

(2) Others, as Delitzsch, Ziegler, Beda, Doderlein, Bertheau, Wardlaw, take khinnam in a different sense, as indicating the escape of the birds - the birds see the snare and fly away, and so in vain the net is spread in their sight. This explanation is in agreement with Ovid's statement, "Quae nimis apparent retia vitat avis." The moral motive put before youth in this case is the aggravation of his guilt if he listens to the enticements of sinners. The teacher seems to say, "Imitate the birds, flee from temptation; if you listen to sinners, you will sin with your eyes open." Is spread; מְזֹרָה (m zorah), expansum, not conspersum est, i.e. besprinkled or strewn with corn as a bait, as Rashi. M'zorah is the participle passive of pual, זֹרָה (zorah), "to be strewn," from kal זָרָה (zarah). "to scatter, or disperse" (Gesenius), and means expansum, because when a net is scattered or dispersed it is spread out (see Delitzsch). Of any bird (כָּל־בַּעַל כָּנָפ khal-baal khanaph); literally, of every possessor of a wing, or, as margin, of everthing that hath a wing, i.e. of every bird. Compare the same expression in Ecclesiastes 10:20, בַּעַל חַכְּנָפַיִם (baal hach naphayim); i.e. "that which hath wings" (Authorized Version).
