The beagle may have (mostly successfully) cleared the garden of the neighbourhood cats, but there are still visitors that she is powerless to defend against. We are regularly visited by several (or more) Hadeda Ibises.
The beagle will stalk the birds from the patio before going full speed (it’s not much, but full marks for effort) at them until they
are vanquished to beyond the city boundaries move to the other side of the garden. At which point she gives up.
But that’s when they are in plain sight on the lawn. When they are in incognito mode in the flower beds, they can go about their foraging with complete impunity.
The Hadeda is much maligned in South Africa, but these particular guys are usually pretty quiet and completely harmless. They can be a bit messy around the pool from time to time, but I’ve not got to the point where I want rid of them.
