Sad end for two falcons

Two of the city's three much-loved Collins St falcon nestlings have died from a fatal infection.

The chicks, followed by thousands on a live webcam atop 367 Collins Street, were learning how to fly when they contracted trichomoniasis, a disease carried by feral starlings and pigeons.

Dr Victor Hurley from the Victorian Peregrine Program confirmed that it was something he saw "only rarely".

In happier news, the third peregrine fledging flew away from the man-made nest, and is believed to be doing well.
