Flying pink whales
At the risk of being boring, I must mention once again that I live in an incredibly beautiful part of the world. This picture of a flock of Greater Flamingos (Phoenicopterus ruber) was taken just a few minutes away from my house.
These elegant birds feed on tiny insects, crustaceans and diatoms, which they obtain by filtering the water through fine bristles in their bill. This is precisely the same technique used by Baleen Whales to extract their tiny food species from the water. In fact many fish species as well as some shark species and many crustaceans and sponges, mussels and oysters are also filter-feeders.
