One of the magpies I release has returned. He looks a bit beat-up and seems very depressed. He landed in front of an open cage and walked inside, hopped onto a branch and hunched down. I put food and water inside but he doesn't look good. There are no avian vets here and the zoovets are shut on Sundays. I'll have to get him out there tomorrow.
Chloraform is no longer available to the public. Looks like Dr Death will have to retire or switch to bottled CO2.
