Who are the "birds of air" in the parables of the mustard seed & the sower?

Majority of commentaries or things you read & online teaching is not pointing in the right direction. The "birds of the air" in those parables is not about Kingdom growth but corruption & infiltration with false teachers, prophets, wolves, foxes & demonic spirits in the churches, getting from worse to worse. The good seed is the remnant within "Christendom" throughout the church age till the rapture.

The bible verse about birds coming to steal seed is found in the Parable of the Sower in:

Matthew 13:4: "As he was scattering the seed, some fell along the path, and the birds came and ate it up."

• Luke 8:12: "The ones along the path are the ones who hear, then the devil comes and takes away the word from their hearts, so that they may not believe and be saved." 

Meaning

• The Seed: Represents the word of God or the message of the kingdom.

• The Birds: Represent Satan or the evil one.

• The Action: Just as birds quickly swoop down to eat seeds left on a hard path, the devil takes away truth before it can take root in a closed heart.

The Parable of the Mustard Seed is a short story told by Jesus in the New Testament to show how the kingdom of God grows from humble beginnings into something massive & grotesque. (This a warning, not a guideline for church growth)

The Story

• The smallest seed: Jesus says the kingdom of heaven is like a mustard seed, which is the tiniest of all seeds a farmer plants in the dirt. 

• The giant plant: Even though the seed is very small, it grows up to be the largest of garden plants, turning into a large tree or shrub.  (The mustard seed only grows in to a small bush, not into a large tree in the time of Jesus; what was he trying to say?)

• The resting birds: The plant gets so big that birds come and build nests or rest in its branches. (Birds of the air are mostly all the time referring to the demonic throughout the Scriptures!)

Main Meaning as mostly commented or interpreted:

• Humble starts: God's work and the early church started with just a few ordinary people, but it grew to affect the whole world. (This part is true)

• Great power: Small acts of faith or kindness can grow into huge results over time.

  (Correct interpretation: Power corrupts & church is infiltrated with the demonic)

• Open to all: Just as birds find a home in the branches, God's kingdom welcomes everyone. 

  (This "open to all" is exactly the downfall, corruption & infiltration in the church, from the institutionalisation of the church in the 4th Century AD to "Seeker sensitive" & so-called "Purpose driven" churches, but there has always been a faithful remnant!)

  Acts 5:13-14

  Yet none of the rest dared join them, but the people esteemed them highly. And believers were increasingly added to the Lord, multitudes of both men and women,
