The breeder/importer from whim I purchased them then suggested to me that I start providing the birds with live food (he actually suggested providing live food throughout the year for all waxbills, weavers ect and increasing the amount when breeding). I immediately mentioned mealworm and he suggested I rather use termites as it is their favorite wild food and it is easily and freely available here.
So I followed the termite harvesting instructions and provided my first termites to my BCCB's. It took them less than a minute to notice the termites and less than 5 to consume all of them - lol. I then added some more and they went nuts, it was so funny to see the 4 of them all eating at the same time. They finished that batch in no time as well. Up to this point I was providing roughly about 100 - 150 termites at a time (I counted the amount 1 bird consumed and multiplied it by 4, how else do you count termites hidden in a piece of dust?).
It then concerned me that they consumed the termites so quickly and I added a big chunk of termite nest core which was overflowing with the little insects. My dominant male jumped on top of the nest and then quickly jumped away as I think the termites were attacking him

My shaftails also ate some termites but not nearly the amount the BCCB's did, none of the other birds showed any interest in them - stars, zebras and javas.
