This year seems to be an off year for the Rufus and Ruby Throated hummingbirds.
We usually have upwards of 20 of the busy little creatures here north of Lake Ontario but only two have arrived so far. I will dig up more information for you ASAP. May 17, 2008
The numbers of Rufus hummingbirds are declining, which has caused the National Audubon Society to place them on a list of "common birds in decline." Biologists are now scrambling to find out why the high-octane birds are disappearing.
Rufus numbers have been falling for 10 years. We cannot prove it is habitat loss, the birds winter in the highlands of Mexico, but fewer and fewer hummingbirds make it to nesting grounds for the past few years. People are clearing land in Mexico to get grass for cattle. People in California, Oregon, Washington and British Columbia are clearing land to put houses on, this has an effect on the migration of these birds. After flying 300 to 500 miles, a Rufus hummingbird needs to eat to survive. If it cannot find food, it will die.

It is the dead of winter in the Northern Hemisphere, the Hummingbirds have gone south, and we're writing - again - about how to count them. For northerners, it's for future reference. The planet is tilting, spring will return, and so will the hummingbirds. Last August we published a method of estimating the number of Hummingbirds you feed based on the amount of nectar disappearing from your feeders. The method we suggested came from a book about hummingbirds by Dan True who, in turn, based his methodology on a 1973 scientific study.
Whenever there are no more hummingbirds to feed. Hummingbirds migrate by internal calendars based on day length, no food availability, so leaving your feeder out will not stop them from migrating, A good rule of thumb is to leave your feeder up until two weeks after the first hard frost to provide extra energy for late-migrating hummingbirds.
