When I was working in Paris, I used to go for a snack in the Tuileries Gardens.
There was a whole group of sparrows there, who got to know me well and wood come and accompany me. I used to share my bread with them, and that always made me happy. I'd put a few crumbs in the palm of my hand and they'd land on my fingers to peck at them.
There were also some pigeons that wanted to take advantage of this and bothered the sparrows, but as they are regulated and it is (probably) forbidden to feed them, I gently chased them away.
I miss my little sparrowfrens in the Jardin des Tuileries.
