Some birds (herons, pelicans, storks, cormorants, vultures, hawks) adopt a characteristic pose where they extend and slightly droop their wings. This behavior is commonly described as "sunbathing" or "wing-drying." It's said that the purpose of the spread-wing pose can be thermoregulation, wing-drying, balance, and/or realignment of feathers. We caught this heron striking the pose on the shore last week.
