30 Birder's Guide to Gear | November 2016 Avoiding Bird Collisions NOTE: These may be very visually dis- tracting. If the exterior surface of the window is mirrored or highly reflective, these solutions may not be visible from the outside at certain times of the day due to shifting light, or may not be vis- ible at all, rendering them ineffective. Long-Term/Semi-Permanent Prevention for the Outside Surface of the Window $$ • American Bird Conservancy (ABC) Bird Tape*, window film (CollidEscape, Feather Friendly, and similar)* ABC Bird Tape is not Bird Scare Tape, and since the writing of this article, CollidEscape has taken over manufac- turing and distribution of ABC Bird Tape. Ordering ABC Bird Tape through CollidEscape may be cumbersome. $$ • Acopian BirdSavers ("zen wind curtains"), which can be installed sea- sonally or permanently $$ • Window clings, stickers, decals (spaced no more than a hand-width apart) $$ • Netting (not appropriate for large windows, may not be appropriate in all seasons in all climates, may entangle birds if improperly installed), may be seasonal or permanent NOTE : These options are often available at wild bird or garden stores. They may be less visually obtrusive when applied as abstract stripes or dots rather than stamped shapes. ALSO CONSIDER: Move your feeders! Top: Stores that sell seed and feeders may have collision prevention prod- ucts for sale. This display of decals, raptor silhouettes, UV liquid, and Bird Tape is at a Wild Birds Unlimited. Packaging and store suggestions may not accurately convey the amount of coverage required to prevent strikes. Photo © Heidi Trudell Middle: Even buildings that are less than 50% glass on the exterior surface can be prone to bird strikes, regardless of window tint. If Acopian Bird Savers were installed, only three or four strings per window would be required for the upper windows. The lower windows are set back enough that items on the inside of the window would be visible, which is ideal for student art, sticky notes, CDs, etc. Photo © Heidi Trudell Bottom: The "corridor effect" is especially apparent in this photo of a church room that has attempted to prevent window strikes with raptor sil - houettes. This attempt is ineffective but would prevent most strikes if the gaps between the silhouettes were 2–4 inches apart. Photo © Heidi Trudell Continued on page 32
