Swift by name and by nature [View all]
Chimney swifts started arriving here last week during their spring migration. There are many older homes with masonry chimneys in my neighborhood in Lancaster, PA. The chimneys offer ideal nesting sites for the swifts. These birds fly high and fast. Auto focus is useless for shooting swifts, which are in constant fight until they come in to roost in the chimneys and other hollows after dark. Following them with a long lens while manually focusing was a challenge.
