I know nothing about it. Therefore I ask.Ajeta wrote: ↑July 21st, 2019, 4:26 pmDifficult question indeed.
As for your example I would ask: What is required for the mother to act in this way? Reaction to danger, ways to evade it, and the protection of young are part of her life. To me her behaviour looks like an adaptation. Similar perhaps to tits (i.e. small birds) which build their nest in small holes/caves in a tree. But they have also been observed to build nests in letter boxes.
If you think differently I would be very interested in your interpretation.
