We have a big hummer flight this year. We have been going through about 10 lbs of sugar a month feeding them. We make our own nectar:
1 cup of white sugar in a quart fruit jar
Fill fruit jar with water
Nuke 5 minutes
Stir to finish dissolving sugar, and cool.
This is a hummer motel. We have a creek in the back yard, with a woodpecker and flicker working the snags, so there are dozens of hummer nesting holes.
We have an outdoor aviary. We have been feeding a birdseed mix for years, and have attracted finches, juncoes, jays, doves, and grosbeaks to the feeder. Bug eaters and meat eaters fend for themselves, but seem to be doing well. We have a pair of ravens in the woods, hawks, owls, vultures, robins, phoebes, swallows, etc. Pumping out 50 lbs. of birdseed a month year after year has done a number on the fertility of the land around our house. The trees are taller, the grass is greener, and the berries are bigger. It's expensive fertilizer, but spreading it is easy.
