The Little Grebe (Tachybaptus ruficollis) not known for parading in front of the cameras, usually will hide when approached. If you are exceedingly fortunate it may just hide behind something in the water (like below) where it thinks it can't be seen......
.....As soon as it thinks you are not going away it will dive and if your fortunate you will catch the tail end.
This week I was really fortunate as this one below was either very bold or had consumed far to much Christmas spirit. Although it was the other side of a small river, it didn't bother much about me being the other side clicking away with the camera.
This distant shot below was taken from a bridge on a different day.
