I know Herons are eating small (baby) birds but in this case it killed a juvenile House Sparrow in front of me. It happened suddenly and I lost time to pull out my camera from the backpack. Swallow it with all the feathers (no cleaning, no grill

).
I'm not concerned about the population of the House Sparrow (and the endemic birds here don't have an overlapping areal with the Herons) but some much more rare introduced birds like the African Silver Bill and the Red Avadavat e.t.c. could be vulnerable.
After that a Yellow-faced Canary - I didn't know they could do this with their lower mandible: it's the same bird. Look at the disposition of the lower mandible on the first photo.
