In recent weeks I’ve enjoyed some time with juvenile Spotted Harriers on the Moolort Plains.
A number of times now while observing the young harriers the peace has been disturbed by the sudden arrival of a falcon, on one occasion a Black Falcon and twice by a Peregrine. Each time the arrival of the raptor was announced by a burst of alarm calls from the local residents and some rapid and haphazard scattering of nearby galahs and corellas.
Galahs are a common prey item of the Peregrine Falcon, as evidenced by my observation near the Moolort Silos. I disturbed the falcon as it stood over its kill in the middle of the road. It returned some minutes later to drag the unfortunate Galah some distance (allowing a quick and blurry image) before departing to perch in a distant tree. Both of these falcon species are extraordinary flying machines, the Peregrine is faster by a reasonable margin, whereas the Black Falcon exudes power and speed on the wing.
