Guide to Species Accounts
Drawing of the Species
Discusses identification, habitat associations, range limits, detectability, historical status and behavior that affect patterns of distribution.
Abundance
From top, numbers on left indicate abundance in Big Rivers, Osage Plains and Ozark natural divisions; numbers on right indicate Glaciated Plains, Ozark Border and Mississippi Lowlands natural divisions.
Abundance as detected on Miniroutes and United States Fish and Wildlife Breeding Bird Survey routes. When no valid data was obtained, this map is absent. (See Abundance text. )
The phenology of nesting-related events is discussed and related to known squences in Missouri and adjacent states. (See Breeding Phenology chart. )
Dates
Span of dates of four confirmed breeding behaviors: nest building, nest with eggs, nest with young and food being carried to young. (See Phenology text. )
Numbers of percentages f blocks in which possible, probable and confirmed breeding codes were recorded. (See Code Frequency text. )
Shading of the 7.5 minute quadrangles indicates possible, probable or confirmed breeding within the block in that quadrangle. Unshaded blocks indicate that the species was not detected within appropriate dates adn in appropriate breeding habitat. (See Distribution text .)
Notes include: Other observations by Atlasers, such as Brownheaded Cowbird brood paratsitism and other related information.
