This is one of several sites in Scotland where Black-throated Divers can be watched from a car parked at the side of a road. As long as the observer remains inside the car the divers will behave naturally. At this site there was no attempt to reduce the level of disturbance caused by visiting anglers so it was no surprise to me that the divers did not breed successfully.

Black-throated Diver with chicks
   

At this site a track runs alongside the loch and is popular with hillwalkers so the divers are pretty much used to human intrusion. I set up my camera behind a hillock on the opposite side of the track from the loch and covered it with camouflage netting, more to disguise it from passers by (pic1) than from the divers.

Only one adult diver was present with the chicks although I could hear a 2nd diver calling from a larger loch about half a mile away. The adult accompanying the chicks spent a great deal of time fishing without success althougth trout were rising all over the loch. Later it guided the chicks to a patch of sedge on the opposite side of the loch from the track and left them there while it swam back to the middle of the loch, whereupon, it took flight and flew low over the heather to the larger loch. Half an hour later it returned with a small trout and fed it to the nearest chick. For the rest of my visit the 2nd chick who missed out on the meal swam back and forth between its parent and its sibling begging to be fed.
