Secondary criteria: genetic diversity, geographi- cal concentration, and current population trends. CRITICAL: Fewer than 200 annual registrations in the United States and estimated global population less than 2,000. CRITICAL: fewer than 300 registered breeding females THREATENED: Fewer than 1,000 annual registrations in the United ENDANGERED: 300–500 registered breeding females States and estimated global population less than 5,000. VULNERABLE: 500–900 registered breeding females WATCH: Fewer than 2,500 annual registrations in the United AT RISK: 900–1,500 registered breeding females States and estimated global population less than 10,000.
