• This marked a turning point in Keulemans’s career, establishing him within the British ornithological community.
• He remained in England for the rest of his life, becoming a highly sought-after illustrator.
• Keulemans developed a distinctive style characterized by meticulous detail and accuracy, essential qualities for scientific illustration.
