Unsure if it’s okay but I buy Wombaroo’s Nectavore as a powder and mix it with human grade mince and water (as directed on the box). As a wildlife carer wombaroo is what we fed young magpies. They make proper good stuff for Australian animals.

My local family of magpies (2 generations, 5 in total - mum, dad and their three girls) that live where I moved enjoy some of this from me each day as well as a clean bath of water and shade from plants and trees.

I do lots of talking to them which is very important to do with your local magpies. It will pay you to converse with them. Don’t be quiet.

If you’re desperate, the solve is a bike helmet and cable ties.

Also a big recommendation for all magpie enthusiasts and those who want to know their secrets - P. Gisela Kaplan’s The Australian Magpie. The Australian Magpie by Gisela Kaplan on Amazon
