Some things just remain a mystery to us about how hummingbirds can remember every feeder they visited from Central America all the way to our gardens as far north as Canada. Many will concur with stories of these tiny birds showing up at windows looking for the feeder that hung there 8 months ago. When they arrive they simply expect the feeders to be where they last left them. The capability of these tiny brains is nothing short of miraculous. I would seriously need a detailed road map to successfully get to anywhere outside a 50 mile radius.
Here is something learned by hummingbirds. This juvenile knows there is food within these flower buds, but hasn't figured out that some are immature buds yet to open. They will experience many flower mysteries over the first year of their life, but will store the key to unlocking those mysteries within their tiny, but complex little brain, never to be forgotten again. What they learn is somehow processed and then placed in the vault where only the valuable information is stored. It truly is remarkable that something so tiny can store so much information, and that doesn't even touch on their physical capabilities.
