Ring neck Doves

Anyone have any suggestions as to what I can feed ring neck doves? They seem to come out after a rain and I've never observed them eating.

A quick online search came up with their diet being mainly seeds, some berries and insects. I would think any good birdseed would work. Maybe try spreading some on the ground.

They're very common here, both in Kenya and South Sudan, and I see them all the time, but I must confess I've never given any thought to feeding them.
