I think it is a termint nest and perhaps, when they move to another one, a pair of parakeets use to nest and have their chicks, I have seen them do that... :)
That makes a lot more sense. I thought it was too big for wasps, but I couldn't think of what else it could be.
The lizard was a matter of luck because whenever I go there I see a lot of them but they are too fast.
Have a good and blessed weekend, my friend!
