Evidence presented to the court proved it was a ballooning company from the nearby town of Schijndel in the south of the Netherlands that had come closest by far to the cage.
Organisers of balloon races typically mark places where animals are on maps for the balloonists, Omroep Brabant, a local broadcaster, said, and the parrots were most likely marked on the map.
"That is where things went wrong," said Bram van Loosbroek, a balloonist who was not involved in the incident.
"Balloonists are never reckless. It's our job and we have to make sure we can continue to do it. And we can only do that if we take the presence of animals on the ground into account,' he added.
The court ordered the accused balloonist to pay the collector and his son a total of €68,000 compensation for the dead parrots, the Dutch News website reported on Wednesday.
The deceased parrots included a €40,000 pair of hyacinth macaws and a yellow-naped amazon worth €1250.
The compensation package includes €14,000 for the sale of any young the parrots might have produced.
