“…However, one study found that Lesser Black-backed Gulls (Larus fuscus) were tolerant of UAV flights even at 15 m AGL, and another found that only 1.25% of observed Black-headed Gulls were in flight during 30-40 m surveys 23,30 . It is generally accepted that tolerance to stimuli can vary among waterbird species, and responses are species-specific 4,41,48 . We reiterate the recommendation from a recent study to conduct baseline tests to determine whether wildlife disperse in response to UAV surveys 24 .…”
