Their arial capability is also astounding, as I witnessed at a
manufacturing plant in the Southern Highlands. The birds were nesting
inside a building which had closed doors. There was a D shaped hand hole
in the door, with the straight part horizontal, about 150 mm long by 80
mm high. The birds were flying through the hole at full speed. Amazing.
