disputes, during the later part of the morning - after they have some food in the bellies??? This might also explain why Scans have started to pay attention to Bari?)

8:57. See Scans feeding Abu flowers. First pokes bill between sepals. Then one seems to poke bill straight a center sepal. Can't see if there is hole there or not.

Or perhaps the Humer in not completely in breeding condition? Or perhaps the attacks occurred because the ♂ Bari, definitely not in breeding condition, "forgot" to "avoid" or retreat in time? Or do carbonaria s.l. individuals tend to dispute with baritula s.l. individuals wherever the two occur together, throughout the year????
