Vögel VIII
Vögel VIII is a German natural history plate book of birds, published in 1836 for students and naturalists, with hand-coloured engravings of corvids and related species. The pictures are small, precise, and labelled with German and Latin names, showing birds perched or standing on plain ground; a designer could take their clean outline drawing, muted tonal shading, and taxonomic plate layout as a model for scientific illustration.
