Species of the day –Back-dated#2 – White-tipped Sicklebill (Eutoxeres aquila)

Here is an amazing example of an adaptation (extreme bill curvature) that allows this species of hummingbird to access flowers that have curved corollas preventing hummingbirds with shorter or less-curved bills. These hummingbirds have a small indent in their forehead that seems to be a place where a lot of pollen can collect. Clearly this is a very neat example of co-evolution.
