Family friend Syd Femtinos was at the fun day with her pet bird called Baby, which is a type of parrot called a conure that Leo used to play with.
She said: “My bird doesn’t go to kids usually, and when they first met, he just flew over to Leo. He spent the whole afternoon with him.”
Ms Femtinos said: “That just goes to show the nature that Leo had.”
The event included crafts, food and drink traders, and entertainment, including face painting, DJs and alpacas.
Funds raised will go to the charity.
