Figures

Figure 1. Distribution of Swainson's Warbler.

This species is quite local and sporadic toward the northern limit of its breeding range.

Figure 2. Annual cycle of molt, breeding, and migration of Swainson's Warbler.

Data represent molt, breeding, and migration of Swainson’s Warbler in the southeastern United States; birds from higher latitudes and higher elevation begin breeding later in spring than southern birds do. Thick lines show peak activity, thin lines off-peak.

Contact call: ML55972601; Flight call: ML0718711.

Figure 5. Display of a Swainson's Warbler.

Birds spread their wings and tail and vibrate them, while walking up and down a branch and frequently turning around. This display is sometimes given during territorial disputes and also prior to copulation. Illustration by Shirley A. Briggs, used with permission of Nancy Greenspan.

Figure 7. Regional trends in Swainson's Warbler breeding populations.

Based on data from the North American Breeding Bird Survey, 1966–2015 (Sauer et al. 2017). Data show estimates of annual population change over the range of the survey; areas of increase are shown in blue and declines are shown in red. See Sauer et al. (2017) for details.
