Pelicans and Doobies Feature Among Large Sea Birds
A historical natural history passage describes pelicans as the largest in their genus, capable of air gliding and rapid diving for fish. It notes their white plumage near Judea and Egypt and Nile and Strymon rivers, their feeding by underwater gular sac, and roosting on cliffs. It contrasts doobies as fearless, easily captured on ships, and indifferent to humans, with bloodless predation on flocks.
