On the morning of our flight home from Argentina, we took a 15 minute walk from our posada hotel to a humming bird garden. The garden was the backyard of some residents of the city. They had been feeding the humming birds for some 15 years. There were literally hundreds of humming birds zipping this way and that. Over 16 different types of humming birds were feeding that day. The humming birds were eating so much of the sugar water drink that the young man who was guiding the tours said he had to refill the feeders every 1.5 hours all day long! It was a delight to watch, listen, and marvel at the wonder of these beautiful and feisty little birds.
