Hannah Hall from Penny's Pigeon Aid tells Rachel Burden about their work to rescue and rehabilitate pigeons. The welfare charity doesn't encourage people to domesticate pigeons or increase their population, but they do want to educate people on these birds and promote kindness towards them.

Café Hope is our virtual Radio 4 coffee shop, where guests pop in for a brew and a chat to tell us what they're doing to make things better in big and small ways. Think of us as sitting in your local café, cooking up plans, hearing the gossip and celebrating the people making the world a better place.

We're all about trying to make change. It might be a transformational project that helps an entire community or it might be about trying to make one life a little easier. And the key here is in the trying. Not everything works, and there are struggles along the way. But it's always worth a go.
