Pinnacles National Monument placed climbing and hiking restrictions back into effect in certain areas Thursday to protect the park's nesting birds.

The monument has populations of several raptors, including Prairie Falcons, Peregrine Falcons, American Kestrels, Red-tailed Hawks, Red-shouldered Hawks, Cooper's Hawks and Golden Eagles.

In 2007, 12 pairs of Prairie Falcons produced 33 fledglings, according to monument officials.

Areas with restrictions include the High Peaks, the Balconies Cliffs area, Little Pinnacles, Citadel, Goat Rock, Pipsqueak Pinnacle, Gargoyle/Piedras Bonitas, Frog/Hand, Egg Rock/Teapot Dome and the Scout Peak area.
