    Right now, the Rufous hummingbirds are between about 50 degrees north latitude and 30 degrees north latitude. A hummingbird can fly around 25 miles per hour. Assuming that the hummingbird flies for 10 hours a day, we can estimate how many miles the hummingbird will travel. 25 miles per hour multiplied by 10 is 250. That means that a hummingbird will travel about 250 miles a day. Assume that today is March 25. March 25 to April 1 is a week. If a hummingbird flies north for about 250 miles a day for 7 days, it would probably fly north for 1,750 miles. I predict that would put the Rufous Hummingbirds somewhere near 70 degrees north latitude and 45 degrees north latitude by April 1. The Rufous Hummingbirds would be in the Canadian provinces of the Yukon Territory, Northwest Territories, British Columbia, Alberta and maybe even Saskatchewan. We can use the same procedure for the Rubythroat hummingbirds. They are currently between 25 and 35 degrees north latitude. If they fly nort!
     h for 1,750 miles, they will end up between 40 and 60 degrees north latitude by April 1. The Rubythroat hummingbirds will end up in the Canadian provinces of Ontario, Quebec and maybe New Brunswick. Both of the hummingbird species may not fly the whole estimated length of 1750 miles in the past week because they might have decided to settle in an area.
