Thank you for the information. Very helpful knowing they will be ok. I figured they would find another food source. Iím glad Iím not leaving in winter. Iím looking forward to finding new birds in southern Oregon. Marlowe

While it may seem harse, you really donít need to worry too much about the birdsí welfare. Feeders actually account for only about 15% or less of their diet. They are mostly dependenet on wild food sources. Your feeders are an easy and reliable source but they quickly find other sources if the feeders are.not available. Even winter hummingbirds (Annaís) are not as dependent on feeders as we tend to believe. During really cold spells when temperatures fall and stay below freezing, our feeders only account for about 20% of the diet and only about 12% during normal conditions. The hummingbirds come first thing in the morning because it is a quick source of energy and then again just before dusk when a large amount of nectar is quickly converted to fat for survival during overnight torpor. During the day they seek sources of natural food (small insects, spiders and their eggs) that provide their needed protein.
If you wish to do so, you could taper off the amount of food offered to encourage them to seek more natural sources more often. It may make the tranistion a bit easier (especialy for your peace of mind), but they will do fine either way.
We have also had a couple of customers come into our store to buy a bag 20 lb. bag of seed to leave behind along with their feeders to help encourage the new owners to continue feeding the birds. Of course, doing so also usually also means an investment in new feeders for your new location.
There are some studies now which show increased health in populations of birds attending feeders over several years (most recent was a 5 year study). The population with no feeders in the same habitat did well and had no negative effects, but those at feeders showed somewhat better health. When the firs,t portion of the study ended, the feeders were removed to see what happened. The birds immediately turned to natural food aources with no negative effects observed. When their health was examined, it soon returned to that of the wild population, but no less. This study concluded that there were only positive affects from feeding birds (providing that feeders were kept clean and good quality food was provided) and no negative results were found by stopping feeding by feeders.
Rest easy and know that you will do no harm whatever tou decide to do.

How should I handle leaving my birds with no food? Should I start tapering now or keep the same amount and just leave them cold turkey (seems cruel) . I have black oil seed, socks for the goldfinches, hummingbird feeders, suet and general seed on the ground. > I donít want to leave but have to. > > Thanks, Marlowe
