I made the graph on the right because I wanted to know the statistics of recovery for the peregrine falcon. The graph shows that in the 1940s there were 350 breeding pairs in the Mississippi River area. 20 years later (1960) there were none. I think that is really sad that the peregrine falcon was gone in that area so quickly. With these statistics it is easy to see why they were put on the endangered species list.

In 1975 the numbers were back up to 324 breeding pairs. Then in 1998 there were 1,593 breeding pairs in the U.S. and Canada.

Finally, in 1999 the falcon population had recovered and there were 200 pairs back in the Mississippi River area.

Thanks to "hacking", a releasing process, the peregrine falcon has recovered over, but it has taken 60 years!

Studying about the peregrine recovery really changes the way I think about endangered species. These endangered species have come back to full power and I’m proud of it.
