I have seen rattan balls, the ones you used to see in a bowl as decorative items, on multiple websites , re-marketed as “bird nesting material holders for wild birds” and similar. I do not know which came first, these plastic ones or the rattan ball ones.
I cannot imagine any nest being more charming than this. Or this. Or this amazing one. Coming across an Observation of a nest makes me ooh and ahh.
When I find a nest on our home it feels like a special gift. They’re going to raise a family near us! It feels sacred. I keep the dogs away, having spent years losing eggs to a previous pup.
I cannot imagine any improvement being made by the insertion of our refuse.
