 Ornithologists and bird watchers have recorded a total of 128 species of birds in the IBA . Several factors contribute to the high total of bird species observed : there is a large area of forest in the IBA , as well as great habitat diversity , with 343 acres ( 139 ha ) of open water that is used by many of the birds , especially bald eagles . The location of the IBA along the Pine Creek Gorge also contributes to the diverse bird populations .
