Bird of the Week: Willy Wagtail – “where’s my dinner Mum?”

The local pair of Willy Wagtails have taken advantage of the great season we are having in the centre this year and so far have raised two clutches, and I'll expect that, as prime examples of avian opportunism in the desert, they may raise another couple yet in this season.

‘Troublemakers for fire’ – Raptors spreading fire in Australian savanna woodlands

Fire provides the opportunity for pyrophilic behaviour by some birds. Brown Falcons perch at the fire-front waiting for grasshoppers, frogs, snakes, lizards and small mammals. Whistling Kites and particularly Black Kites, Milvus migrans, spectacularly hawk around the curtain of flame, preying on grasshopper, cockroaches and other small fleeing animals. Local Aboriginal people believe that Brown Falcons and Black Kites set fires by carrying burning sticks to new locations and drop them into dry grass on unburnt grounds.

What was the first name for grasswrens?

In Pitjantjatjara country we know that the local name for Rhipidura leucophrys is tjintir-tjintirpa.

RIEL Seminar – Brown Falcon and Black Kite as propagators of fire in the Australian savanna

Anecdotal historical reports from qualified observers support the hypothesis that this is a hitherto-undocumented tool-using behavior that, if verified to satisfy the standards of Western ecologists, will have important ramifications for understanding pyrophytic landscape evolution as well as human-bird relationships.

Why Malheur NWR matters and “armed, out of state militia groups” don’t

The occupation of Malheur by armed, out of state militia groups puts one of America’s most important wildlife refuges at risk. It violates the most basic principles of the Public Trust Doctrine and holds hostage public lands and public resources to serve the very narrow political agenda of the occupiers. The occupiers have used the flimsiest of pretexts to justify their actions.
