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. ”
