Raptors, also known as birds of prey, include hawks, eagles, owls, and falcons. They are renowned for their exceptional hunting skills, aided by keen eyesight, sharp talons, and hooked beaks.

Did You Know?

Marsh-Billings-Rockefeller is home to 17 documented species of raptors, including hawks, owls, eagles, falcons, and vultures. From the majestic bald eagle with a six-foot wingspan to the smaller broad-winged hawk, known for its maneuverability in old-growth forest ecosystems, these incredible birds of prey contribute significantly to the park's biodiversity and ecosystem health.

Importance of Raptors

Raptors play a critical role in maintaining ecosystem health. As keystone predators, they help regulate populations of small mammals, birds, fish, and reptiles. Monitoring raptor populations can provide valuable insights into ecosystem health; declines in breeding success may indicate environmental imbalances.

Threats to Raptors

Raptors are vulnerable to various stressors, including:

• Habitat Loss: Destruction of nesting and hunting grounds.
• Disease and Pollutants: Exposure to harmful substances can impact health and reproduction.
• Climate Change: Altered habitats and food availability can affect survival.
• Human Disturbance: Human activity can lead to:
  • Avoidance of nesting sites.
  • Nest abandonment due to disturbances.
  • Increased vulnerability of eggs and young birds, as startled adult birds may flush from nests, leaving their offspring exposed to predators and harsh weather.

Given that most raptor species have low reproductive rates, typically producing only 1-2 fledglings per year, repeated breeding failures can significantly impact overall populations. Therefore, protecting their habitat and minimizing disturbances is essential for their survival at Marsh-Billings-Rockefeller.
