Détails de l'observation
Four flights were observed overhead averaging ~30 birds per flight. Each flight was observed heading from the north to the south. Each flight was arranged in an undulating v-formation with some individuals occasionally dropping out of formation and then working back into the formation. The birds were buff colored from below with dark outer wing tips. Heads/necks were clearly extended straight and ahead of the torso and legs/feet clearly trailed behind the birds. A recording of their flight call is attached
