Many bird lovers are dismayed when birds strike their windows. These collisions can result in injury or death to the birds and are the result of the birds seeing the surroundings reflected in the glass and expecting to fly through the area in the reflection.

One way to reduce the number of strikes is to break up the reflection. The Lehigh Gap Nature Center will hold a workshop on creating a variety of window decals designed to reduce bird strikes at 10 a.m., Saturday, Feb. 22. The workshop will involve the use of CollidEscape, the material used to make the bird decals on the windows at the Nature Center.CollidEscape is a perforated vinyl material that adheres to the outside of a window. It appears white from outside, so the birds see the material and not a reflection. From inside, the material is black and visibility is about as clear as looking through a window screen. Templates of birds, flowers and leaves will be available. Please bring scissors.The cost of the workshop, will include the cost of the material, and is related to the size of the window. Material for a single, small window, such as that in a door, is $15 for a 1-foot by 2.5-foot sheet of CollidEscape. For a medium-sized double-hung window, order a 2-foot x 2.5-foot sheet for $25, and for a larger window, a 2-foot by 5-foot sheet will be $45. The more of the window's surface that is covered, the fewer collisions there will be. Participants can register for multiples of each or a mixture of pieces.Register by Feb. 1 by calling 610-760-8889 or by sending an email to

Box 198, Slatington, Pa. 18080-0198, and must be received by Feb. 5 the appropriate amount of CollidEscape can be ordered for the workshop.Those who are unable to be there the day of the workshop, can still order CollidEscape for a do-it-yourself project.
