Het intieme leven der vogels

"Het intieme leven der vogels" by Jac. P. Thijsse is a natural history study written in the early 20th century. It offers close, field-based portraits of Dutch birds—especially terns, gulls, and waders—focusing on behavior, breeding, and the case for bird protection. Lively observation, practical method, and gentle advocacy invite readers to trade guns for binoculars and camera and to help build a truer understanding of birds’ lives. The opening of the work sets its purpose in a preface—arguing that we know too little about birds’ daily behavior and urging careful field study for both science and conservation—then moves into vivid observations from the Texel polders. The author sketches the colony life of lapwings, redshanks, oystercatchers, plovers, terns, and black-headed gulls, describing nesting grounds, the look of eggs, and the birds’ fierce defense of broods. He questions tidy myths about “protective coloration” and decorative nest-building, suggesting practical explanations and calling for systematic observation from a hide. From this shelter he contrasts Arctic and common terns, watches incubation exchanges and defensive dives (even at sheep and windblown paper), and notes Sandwich terns breeding among black-headed gulls while lamenting their decline. He details black-headed gull nests, hatching and chick care, the young leaving nests early, and a remarkably flexible nesting and feeding repertoire—from fish to grasshoppers, ants, and dragonflies, and even foraging in fields and towns; terns likewise hawk insects. Brief sections outline seasonal plumages, staging flocks on the coast, the complexity of migration, and the promise of bird-ringing. The excerpt closes as he explains how newly fledged gulls drift into small bands of roving yearlings that effectively guide post-breeding wanderings.
