Think
and Discuss!
This satellite image was taken on April 4, 2009.
The
cloudy areas show windy cold fronts that moved across the country.
During that few days, we had loads of rubythroat
sightings reported. The first ruby-throated hummingbirds were also
spotted in 7 new states. (The orange dots show approximately where.)
- A
few days after this was taken, there were few hummingbird sightings
reported. What do you think happened?
