A birds nest, complete with eggs, has been found in the wheel housing of a jet aircraft that's arrived from the United States.
The Boeing 737 arrived in Auckland last week from Arizona, to be dismantled.
Ministry for Primary Industries team leader, Steve Gay, says a quarantine inspector found the nest among other debris after being alerted by engineers working on the plane.
He says the nest, made from mud, feathers and straw, contained four eggs - two which had hatched.
The bird species hasn't been identified.
