Bird language

I thought, perhaps I do understand the Lineated Barbets now, as I spent sometime listening to the exchange between the two barbets, calling out so vibrantly in the thick foliage.  It was a persistent throaty call that first caught my attention and then one flew in, but did not seem to attempt to do anything except preen.

Meanwhile, another flew in and I thought it was to feed on the MacArthur fruits as it went straight to the palm tree.  Instead on close examination, I discovered that it was just checking out the fruits.

 

Then it flew off and the throaty calls continued until the earlier one flew back in, looked around before it flew down to the fruit, but to another bunch.
Well, well, going by the throaty exchange, perhaps I could gather that one was actually calling for the other to come and feed, and after checking to ensure that the fruits were good enough for the taking, although the other chose to go for another bunch.
Fascinating, that's why bird watching can be so fascinating and entertaining.
