MELBOURNE, Australia (AP) _ Workers at a city building site have stopped work to prevent disturbing the rooftop nest and eggs of two rare and wayward falcons.

The workers' union, the builder and the site owner agreed Tuesday that work will not resume until the two eggs hatch and the chicks are able to fly.

The peregrine falcons, which often fly at speeds of up to 150 mph to catch small birds, usually nest in rugged timber country on cliffs or in high tree hollows.

''In Victoria (state) they are classified as threatened wildlife and to have them in the city is unbelievable,'' said wildlife officer Tony Zidarich.
