A pair of Western Grebes start their famous mating run only to be joined by a third uninvited guest (the one in front).
If you are in the area, Lake Hodges is totally full of Western Grebes running around. It’s amazing to watch, although they are really far away. They are even too far for my Nikon P600 to get a clear shot. This was the only group that was close enough to get a good photo.
