Bats: Heroes of the Night

As the day starts to settle into the night in OCParks’ Irvine Ranch Open Space, bats awaken, stir and streak into the evening sky. Come hear fascinating tales of our flying mammals. We will head out towards a popular roosting location as we watch our nighttime heroes begin their nightly adventures. This program is ideal to visually observe the bats in flight, though bat detectors are available to listen for their high-frequency calls. Be prepared to walk about 1/2 a mile. Dress warmly as it may be a chilly evening. A camping chair is welcome as we will enjoy an extended period of time listening for bats that fly about in the night.
Nighttime Bugs: Baker Staging Area

Join us for this evening program as we explore biodiversity at the local level with that most diverse group of organisms, the insects! Taking advantage of the fact that UV light is highly visible to most insects, we will attract them by using black-lights (low energy/low frequency UV lights). We can then examine them up close, record the different types (and their numbers). Don’t forget your camera as you’ll see creatures that are normally buzzing around, but not highly visible. You will be able to help us document what we find.
Reviewing the 1-through-5 Difficulty Ratings will help you evaluate your readiness to participate in this level-1 activity on the land. Please visit our FAQ page for answers to activity specific questions you may have prior to registering.
