Every spring, usually near the end of April, we have one of the most fun activities of the year; our annual Bird-A-Thon. In addition this is one of our major fund raisers where teams of birders cooperate to sight the most birds in the IWV area over a 24 hour period running from 6:00 PM on the first day until 6:00 PM on the second day. Teams meet at a local Pizza shop after birding all day to sum up and reconcile all the sightings.
Teams obtain pledges from members and the public to sponsor their team by making a donation, either a per bird or flat donation. The resulting proceeds are used for support for the Kern River Preserve and our own educational endeavors.
