A tailless molting male Hooded Warbler photographed on 23 August 2019 near Chapel Hill, North Carolina. Warblers in this molt stage are typically replacing 50–67% of their 48 flight feathers simultaneously, including all 12 rectrices of the tail and 6–10 of the 18 remiges on each wing. Warblers in high-intensity molt usually skulk in thick vegetation, fly poorly and reluctantly, and are infrequently seen or photographed. Photo by Mary Parker Sonis.

Differences between Partners in Flight roadside sample-based population estimates and spatial model “pixel”-based population estimates align with roadside count and habitat representation differences across 81 species in Northern Alberta, Canada. Red dots indicate species that are well-represented along roads; blue dots indicate species that are under-represented along roads. Filled dots indicate statistically significant differences between population estimates, P < 0.05. (Species codes and values for species represented by unfilled dots can be found in the paper.)
