Ruby Throated Hummingbird, taken through my kitchen windowChances of discovering a lifer, or even a county lifer in my back yard are getting seriously low nowadays. The
Connecticut warbler I had early June might very well be the last lifer I could get while sipping a
glass of white wine on my deck.
I was thinking about the next potential target the other day, and suddenly I thought about one possibility. A small, remote but real possibility.
I am talking about the
Rufous hummingbird. looking at the
Michigan Audubon Record Commitee database, I found the following records :

that's 24 record in 34 years, for the whole state. Obviously, I will need a little bit of luck to find one of those little guys feeding at my windows. Having said so, there is a few encouraging facts that makes me think I have a decent chance.
- there is 24 records in 34 years, but 20 in the last 10 years. So that gives about 2
Rufous hummingbirds per year that are supposed to cross the 170 miles long
michigan/
ohio or
indiana border every year. Assuming the attraction radius of my feeder equipped backyard is 100 m, the odds are about 2*100/(170*1609)=0.007%
Ok, that does not seems a lot at first sight.
But I have another point I would like to make.
How many
Rufus hummingbirds are out there really? They seem to show up late in the fall, when most
birdfeeders are already washed and back to the storage area. So, the 2 birds a year that are reported are actually seen by a few selected birdwatchers that are dedicated enough to keep their feeders free of ice through the fall/winter. How many of these people are they in
Michigan? I would bet there is no more than a few dozen of those geeks in my state
Furthermore, 2 birds a year are only the accepted records by the
Michigan record
committee. I've heard these guys are pretty picky and tend to only accept very well documented records. I'm pretty sure those guys are so picky that most people would not even bother to report a
Rufus Hummingbird, specially if they could not take a picture.
That leaves me with only a wild guess to make. I would bet my chances are not 0.007%, but maybe one hundred times higher than that. That's close from 1%.
Call me a fool, but I like my chances. I'll let you know in December.
