Female blackbird?

While I was shaking the tablecloth outside, I happened to turn towards the acacia tree. There she was, perched on one of the stumps. I looked at her, she looked at me. I don’t suppose you’d wait for me to get my camera, would you? So slowly I retreated into the house, got my camera and slowly went out again to find........ she was still there! Can’t believe my luck today. I took some pictures and I swear that in some of them she’s got both legs and feet on the stump! My interpretation is.... she was doing the tree pose! A yoga lover!
