I knew a herring gull who behaved similarly. She would perch on my head and emit loud territorial calls. If I sat outside on a summer’s day she would sit next to me and take a nap. Unsure if she was quite right in the head. I garden as well and have a couple of Robin’s that will appear. Not quite so friendly as Bob but still wonderful. It has been a great time for getting close to nature. One of the good things to have come out of this strange time.
Sorry about your loss. Keep up the good work. I like to think this is true as well.I mean maybe it is a comforting mechanism but it doesn’t matter as long as it brings some comfort to someone grieving that’s all that’s important…when my dad died early and my partner left me with a baby I suddenly became focused on the birds in the sky and I thought I could feel his spirit in the birds…then I started noticing a Robin here and there and each time I saw the Robin I felt like my dad was still there.it allowed me to grieve and let go of some of the sorrow..his mother and him loved robins and had a special affinity with them.
