Torresian Crow

Description:

My 700th spotting on PN. It has taken me a little under 6 years to get here, but hey, slow and steady, right?! :) I didn't know what number 700 was going to be, but then these crows made their appearance, and had it not been for their raucous and persistent calls, I would have missed them entirely. I've learned to listen out for crows and other local bird species, particularly Australian miners, butcherbirds and magpies, because they are very vocal when danger is spotted. There was a sizeable bird nest in a large tree at this location, and I was almost certain I would look up and see a python or some bird of prey, but alas, I spotted nothing untoward and they all went quiet as soon as I arrived. A false alarm? It appears so, but it may also have been a territorial dispute. There's plenty of info regarding this species at the reference links. PS: Regarding the bird in the lead photos - I have no idea why there's a mass of feathers missing from the nape of its neck. Initially I thought it had been mauled, but upon closer inspection I could see no visible signs of blood. That's not to say it hadn't been attacked because it also had an injured foot, but it was actively moving about and feeding, and in no way gave any indication it was ill. An old bird, perhaps? They can live up to 30 years. The bird raiding the bin is a juvenile - it's eyes are chestnut brown, whereas the adult birds have white eyes. Nestlings have blue eyes (and shorter wings and tail).

Habitat:

Open forests, eucalypt woodlands, scrublands, along watercourses, farms and city suburbs with tall trees. They require tall trees for nesting. Sedentary as adults, but immatures form nomadic flocks. These birds were spotted in Sunnybank, a suburb of Brisbane.

Notes:

In Australia, there are five native corvid species: Australian Raven (Corvus coronoides), Little Raven (C. mellori), Forest Raven (C. tasmanicus), Little Crow (C. bennetti), and Torresian Crow (C. orru). As well as these natives, the House Crow (C. splendens) from the near north Asian region has made regular appearances as a ship-assisted vagrant. To date, this species has not become established in Australia. https://environment.des.qld.gov.au/wildl... How to tell the difference between these corvid species of crows and ravens? It seems to be a simple matter of geography. Australian corvids are almost identical in appearance, so the most reliable way of identifying them is knowing which ones live where. Melbourne and Adelaide has the Little Raven. Perth, Canberra and Sydney, the Australian Raven. Hobart, the Forest Raven, and Brisbane and Darwin, the Torresian Crow. The Little Crow seems to favour the drier regions of Central Australia, but can also be found in Adelaide and Perth. Confused?
