Robert Service,  The Zoologist (1902)

“ Early in the evening they can be seen snapping up many easily recognizable species. I have seen them take moths so small as a Depressaria. The Gulls capture the moths most dexterously, and it is curious to notice a Gull occasionally make a rush and chase a Bat, probably getting jealous of its moth-catching rival, or perhaps mistaking the flying insectivore for an insect of more than usual dimensions. Standing beneath a tree, over whose top a Gull is gliding, one hears the chuckle of satisfaction emitted when it catches and swallows a victim. ”

“ This moth-catching habit, which has developed so regularly in recent years, occupies, as I have stated, a well-defined period, beginning quite abruptly, and almost to an hour at the same time each season. In various ways, which need not be particularized, I have ascertained with tolerable certainty that throughout the region specified the moths thus caught are for the purpose of feeding the young. No doubt, immature non-breeding birds take part in the pursuit, and apply the proceeds to their own uses, but the main purpose is capture by the breeding birds to feed their young ones. ”

“ For long subsequent to that year they could only be seen capturing moths on the wing during similar warm summers; but for at least the last dozen of years these Gulls have regularly and constantly presented this habit. Either from choice or necessity the catching of Lepidoptera after nightfall has become a confirmed annual practice. Formerly we meet, in ornithological literature, with short and fragmentary allusions to this species feeding on the Ghost Moths, picking these from the grass-stems. There seems every reason to believe that moth-catching by this species began with the Ghost Moth. ”
