Mrs. Trigg is “a good-tempered woman” who, like her husband Mr. Trigg, is foolishly nonchalant about the birds. Upon greeting Nat following his first late-night tussle with the creatures, she dismisses his story as a nightmare and suggests he write to the newspaper for an explanation. She also wonders if the cold snap is coming from Russia, further echoing Cold War fears. Nat finds her body the next day beside a broken umbrella and a pile of dead gulls.
