We are always looking for new hummingbird feeders as these birds are fun to feed and watch. We tried out this line of feeders from First Nature last year and were very impressed with them. They hold up well, do not discolor in the sun and are easy to clean and fill. They have wide mouthed openings so cleaning them is much easier than the tighter bottleneck feeders. Best of all, the hummingbirds loved them too! They are a cheaper, but well-made alternative to some of the more expensive hummingbird feeders.
