Abstract Great Black-backed Gulls (Larus marinus) are known to prey upon a wide range of bird species, particularly adults, young, and eggs of seabirds and waterfowl. Here, I provide the first account of Great Black-backed Gulls pursuing and attacking, in flight, a medium-sized wading bird, the Glossy Ibis (Plegadis falcinellus). I recorded two observations at Stratton Island, Maine, the northernmost breeding site for the Glossy Ibis in North America.

Delayed capelin (Mallotus villosus) availability influences predatory behaviour of large gulls on black-legged kittiwakes (Rissa tridactyla), causing a reduction in kittiwake breeding success
TLDR
The frequency of gull predation was significantly correlated with the percentage of kittiwake eggs and chicks that disappeared each week and the frequency varied significantly among the three periods, being highest after gull chicks hatched but before the capelin arrived.
Predation and Piracy by Gulls at a Ternery in Maine
TLDR
It will be shown that a substantial number of chicks are now lost to the large gulls and that fish-stealing is likely to be significant when the terns find fishing difficult.
Using radio-transmitters to improve estimates of gull predation on common eider ducklings
TLDR
The recovery of radio-transmitters attached to eider ducklings and subsequently retrieved from Great Black-backed Gull pellets suggests that traditional methods of estimating the number of eider Duckling mortality on the Wolves Archipelago, Bay of Fundy underestimates the true number eaten by gulls by a factor of 5-17.
Predation and breeding success in roseate terns (Sterna dougallii)
TLDR
This study determined how predation affects the breeding success of threatened roseate terns nesting on Country Island, Nova Scotia, Canada, one of only three Canadian breeding colonies and the first to be systematically studied.
Factors affecting duckling survival of Eiders Somateria mollissima in northeast Scotland
TLDR
Reproductive output of the Ythan population probably limits the rate of population growth, but numbers of breeding birds seem to be regulated by other factors acting after fledging.
THE FOOD OF SOME LARUS GULLS
TLDR
The food of L. argentatus on Skomer and Skokholm Islands (Wales) was studied by the analysis of stomach contents, pellets and direct observation and there appears to be little competition, at least in the areas studied, between.
