This is one of the adult Black-collared Barbets that nested within five meters of my Auckland Park office for several years. While working I was able to see them brining food to the young, I got to see the brave young ones sticking out their heads for the first time, tapping on the edge of the nesting hole and demanding food from the ever working parental pair. I also, over the years, got to know that an extended family system would be created, where the adolescents from a prior year would help the parental pair raise the next bunch before going off to find territories of their own.
