It's a funny thing, years before Y-T ever started, we used to see hordes of Magpies heading home from *Victoria Park,* even though they were train passengers they seemed to behave just as these feathered maggies do.
Yes, adult males and females have black feathers, not greyish, on their chests and undersides, and adult males develop white feathers on the grey part of their shoulders. Adult females retain the grey feathers on their shoulders. .ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KqSbDcks_uA.html&ab_channel=TheDodo
It is one of my greatest wishes before I die, to go to Australia and interact with these amazing corvids. ❤️ I have my neighbourhood Northwestern crows here, who wait outside my window for peanuts, but they are more distant and don't make that beautiful sound. Canuck is Vancouver's famous crow - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-flU0rDDGtHU.html - but sadly he's been missing since 2019.
They aren't corvids, just similar colouring. They're Artamidae. Jerome Fuchs and colleagues extensively analysed both the mitochondrial and nuclear DNA of the Artamid family. The results suggested that the group may have existed in Australasia for 33.7 to 45 million years. Very distant cousins maybe? :)
Are you a Bogan by any chance? I only ask because you drive a Bogan Holden Commodore SS V8 (it's at least 20 years old and a typical Bogan mode of transport) and in one of your clips you're dressed in an Aussie flag costume (another common Bogan fashion style!)
With what I've noticed with my local subspecies (which I don't believe is the same as the ones this channel meets, unless they happen to live in perth :P) is that the juveniles/yearlings have the same back markings as females- the "lacy" pattern. It would seem they don't develop the solid white backs as males until adulthood. So who knows! This one is def a youngster though, you can tell by the grey belly, unlike the back markings it seems to be fairly universal amongst all maggies.
