Breeding Timeline
This timeline illustrates the migration/dispersal period and the breeding period for each species. Use it to learn when species are nesting in Maryland and DC, and when their migration or dispersal overlaps with their nesting. During their migration/dispersal period, weak codes should not be used (e.g., code H, code S, or code M), while other Probable codes should be used with acute caution and always supplemented with comments.
