The Bohemian Waxwing is the Cedar Waxwing's larger, wilder northern cousin — a sleek, crested bird with a peach-blushed face, waxy red wing tips, and an air of elegant unpredictability. They breed across Canada's vast boreal forest and descend on towns and cities in winter in spectacular, nomadic flocks that can number in the hundreds or even thousands. When a flock arrives, they strip berry-laden trees with astonishing speed and efficiency, gorging on mountain ash, crabapple, and hawthorn fruit. Their movements are driven entirely by food supply, making them gloriously unpredictable — some winters they flood southern cities, other years they barely appear. A Bohemian Waxwing invasion is one of Canadian winter birding's greatest events.
