The outside is tough and waterproof. The hummingbird uses spiderwebs to hold its nest togtether. It lines the inside with cobwebs and feathers. The hummingbird lays two white eggs, each the size of a pea. The hummingbird feeds every 10 minutes throughout the day.
Honey ferments easily, and can cause sores in the hummers mouth.
Artificial sweeteners have no food value. Do not use red food coloring in your solution, as this could be harmful to your hummers. Change nectar every 3 days, more frequently in hot weather. If you see black spots inside your feeder this is mold and you will need to scrub it out with a good bottle brush. If you can't reach it with a bottle brush you can add some sand with water and shake the feeder to remove the mold.
