The abundance and range data tables are a great way to learn about what percentage of the population occurs in each state or region throughout the year. Not only can this information help you find more birds, the abundance and range numbers quickly pinpoint the states and regions critical for population survival.

The Baltimore Oriole is a common bird throughout the eastern part of North America where it breeds in the United States and Canada and winters from Florida to northern South America. During the non-breeding season, 21% of the population can be found in Honduras and El Salvador suggesting that these countries are important part of their annual cycle.
