Species of the Day: White-crested coquette! This might be one of my favorite species. ‘Lophornis adoriblis’ might say it all. Weighing in at a terrifying 2.5 grams, it is one of the smallest hummingbirds in the world. This one actually flew into the window of the kitchen today and it was brought to Adam and I to save. We fed it sugar water and it flew off.
