This year’s Great crested grebe chicks are now at that awkward teenage stage, no longer the cute chicks they once were but also not yet the elegant adults they will become.

The two above are quite fluffy still, and their black-and-white head stripes remain very obvious, whereas the juvenile bird below, which must have hatched earlier, is beginning to lose its stripes, and its body plumage resembles much more closely that of an adult. By the end of the year, all three will have moulted into their adult plumage and all traces of their babyhood will have disappeared.
