A BAT walk in Keighley's Cliffe Castle Park caused quite a flutter.
Organisers say there was an "amazing" turnout for the event.
The walk was staged by Cliffe Castle Support Group and led by Ian Butterfield, of YORGreenCIC.
Group chair, Elaine Cooper, says: "The turnout was amazing, and it was a real family gathering.
"Ian started the evening with a children’s game of 'moth and bat' whilst waiting for the light to fade.
"The Cliffe Castle bats didn't let us down! As we walked down the side of the woods and over to the pond the bats were in plain sight against the clear sky, catching nocturnal insects on the wing.
"Evenings like this are so special, to be able to share 'nature in action'."
