- A highly social creature, the White-throated Swift sleeps in roosts of hundreds of birds, typically in larger cavities in cliffs and large rocks. In the evening they gather above a roost, ascending beyond view and then descend as a group. With a swirling in front of the roost crack, individuals enter the roost several abreast. Occasionally one misses, bouncing off the entrance to rejoin the swirling mass.
