Подробности наблюдения
Gulls gathered up along the eastern part of the lake and started moving north along the ridge. Several waves of groups of about 100 birds, vocal. Interestingly, I observed a cool behavioral aspect to the migration; as a group of gulls flew north, an individual would leave the pack and fly back south to gather up stragglers left behind, then turn north calling and leading the slower ones to the main group. Pretty cool.
