 In a study on Amchitka Island from 1968–1973, it was found that an average of 18.6 eyries on the island (over the course of the study) were in no close proximity to seabird colonies as no sizable colonies existed on the island.Instead, these large, robust birds fly out to sea to hunt up to 50 miles from land, rather than inland toward the interior.Which is quite an impressive physical feat as they must either eat their prey while flying or carry the prey back to land to perch and then consume it, as peregrines are not known to be able to rest and stay afloat on water as seabirds do.
