A problem plaguing birders around the world is unwanted guests, and when you are feeding your birds the very best in bird feed (thank you!), it is not hard to imagine why. In addition to the number of feathered guests our bird feeders enjoy, they are also occasional feeding grounds for a variety of mammals including (but not limited to) raccoons, bears, deer, chipmunks, and squirrels, to name a few.
While not all birders are concerned about who or what is utilizing their bird feed, there are some of us out there that prefer to leave the good stuff for the birds. In any case, when it comes to feeding hummingbirds, there are a number of guests who have the ability to make a mess of things and ultimately become rather bothersome to many of us. Those guests often come in the form of small insects such as ants that can very quickly take over a hummingbird feeder given their strength in numbers.
