I was fortunate to see two groups of 3 glossies close to each other. In this group, I could not work out the relationships. There seemed to be perhaps two juveniles? And no adult female? The second photo seems to show feeding, which I observed a number of times. However, there was no calling from the bird being fed - in fact, the two birds in the first three photos were silent the whole time, whereas in the fourth photo, there was some calling.
