Photo: Neil Paprocki Fig. 2 from the article: Continent-wide average latitude (A) and seasonal distribution of mortalities (B), (C) across the full annual cycle derived from 186 GPS-tracked Buteo lagopus in North America from 2014 to 2026. (A) Average daily latitude (± SD) for all 186 GPS-tracked B. lagopus used for seasonal definitions in survival models. Full annual cycle distribution of 80 mortalities colored by major cause of death during baseline (B) and avian influenza (C) study periods.
