Once their single chick hatches, both parents take off early in the
morning and usually do not return until the sun goes down. They fill
their throats with insects and will go as far as they need to find
them. At 50 mph that works out to at least a 300 mile range. So a
Central Cascades adult Black Swift could fly anywhere in the state and
still get back before dark.
But if you see them late in the day, they are headed for home, or know
they can make it before dark.
