About hummingbird food, How often do you change the food? I hear some change it every week, every month, and not as much.
"Every
month"?? Or
"not as much"?!? :eek!: Sorry, but anybody who leaves their hummingbird feeder out for a month or more had better have a liquor license, because the solution will turn into a really nasty "home brew" after a week or so under most conditions. You might ask whoever recommends this whether they'd drink a glass of Kool-Aid that had been sitting outdoors for a month!
Every 2 to 3 days is the standard recommendation that you'll find in most books on hummingbirds and in the instructions included with most of the mass-produced feeders. If you feed hummingbirds through the winter, you can go as long as 5 ot 6 days between changes as long as the temperatures are cool enough. If your feeder isn't in a protected spot, you may need to rinse it out and change the solution after every rain. And
always change the solution if you see cloudiness, mold, drowned critters, or other floaty things and/or if the solution has a "beery" smell. Cleaning your feeder (or at least rinsing it with hot water) before every refilling will help keep most spoilage problems to a minimum.
Absolutely make your own feeder solution. There's nothing in the commercial "instant nectar" products that makes them worth the cost, and most contain unnatural chemicals that are potentially harmful at a hummingbird's high intake rates. The standard recipe is
4 parts water to 1 part white table sugar, but you don't have to measure it exactly.
Don't add artificial coloring or substitute honey, powdered sugar, brown sugar, "raw" sugar, etc. Though boiling the solution is often recommended and some people say it helps retard fermentation, it's perfectly okay to make it with cold water.
