Why is peregrine are endangered?

Answer 2

Peregrine falcons were once considered endangered (and are now considered a threatened species) because they were sensitive to a poison called DDT. Small birds (which peregrines eat) eat the insects that were sprayed with DDT. The DDT would build up in the falcon's systems, and when they laid their eggs, the eggshells were too thin. When the falcons sat on the eggs, they broke and the baby inside did not survive. Luckily, DDT has been banned in the US, and the peregrine falcon population has recovered somewhat.

Answer 3

The piping plover, Charadrius Melodus, became threatened due to construction of beachfront property on its nesting grounds, but has resurged recently in some areas due to concerned wildlife agaencies.
