Barbet on the hunt but ....

It was a rare opportunity to observe the Lineated Barbet scouting for a nesting site.  What alerted me was the pair calling out to one another, and hurrying to the location I could see one of them flying about.  I eventually managed to track one and saw it checking out a potential site as it proceeded to chip at the tree top, not easy to track as the top was heavily blocked, which I immediately thought was a great choice of the bird.

However soon after, another one, not sure if it's the same bird was seen at another tree.  It proceeded to peck too into the tree but I had my reservations about this choice because it seemed pretty low for comfort.  Having observed the birds' presence around the area for a couple of days, it looked like they too found the location unsuitable because this site too was eventually abandoned.
