Chimney Swift Night

Join Mill Grove at this year’s
Chimney Swift Night, on Wednesday, July 17th from 6:30 to 8:00 pm in
the pavilion. The chattering in your chimney may actually be
birds and not bats. Chimney Swifts are migratory birds that return to
Pennsylvania in early April from as far away as South America. Like bats, these
birds once nested in old hollow trees and now nest almost exclusively in
chimneys because old trees have been removed from the landscape. And, like
bats, they eat lots of flying insects.

The way you tell if
you have birds or bats is by going outside at dusk and watching whether
something comes out of your chimney or goes in. Bats are just getting ready to
exit the chimney to forage for insects at dusk. Chimney swifts look a lot like
flying cigars and will fly into the chimney to roost for the night. These
fantastic fliers do almost everything on the wing—eat, drink, break off twigs
for their nests and are even thought to copulate in flight. 

This is a family
program for all ages and includes an education program, activities, and a short
hike to view the birds! This event is free to the public and no reservation is
required. For more information on the Chimney Swift Night, please call
