Bird food dispenser from repurposed tin can:
This is a repurposed corned beef can, using zip ties and a piece of wire that wraps around the can and each end is the attachment to a cage. The two plastic ones give scale of what else I have available, the smaller one being 2". They are handy for a few reasons: they don't break when they freeze (the smaller plastic ones are especially prone to.) They are narrower than the big feeders, so you can fit two of these in the door of a small car cage. They cost nothing as opposed to the plastic ones that are about $5.
Edit: these are the corned beef cans that have the key gizmo for opening on the side, so there was no cutting!
The picture is with these hooked onto the outside of a cage for presentation purposes: I couldn't get a decent picture of them on the doors due to light challenges, sorry!
As per discussion, I was under strict lockdown. There was no spread of the virus in our jurisdiction, and we weren't even free to go get our mail. No cellular reception, at that time, still copper telephone lines, so antique fax or dialup!!! was the extent of digital communications. Harassed frequently for driving to a weak LTE signal that wasn't strong enough for calls, but strong enough for texting, mostly, with errors, , otherwise, life as usual. Gatineau mountains, Québec.
