See “exterior Glass” pages 20-21. <br /> ƒUse angled glass, between 20 and 40 degrees from vertical, to reflect <br />the ground instead of adjacent habitat or sky.18 <br />Clear barriers such as transparent bus-shelters, skyways, linkways, <br />railings, windscreens and noise barriers create a serious hazard for birds <br />because they are invisible, causing a deadly fly-through hazard. <br /> ƒavoid use of transparent materials in these structures in any location <br />where birds may be present. Use translucent or decorative glazing as <br />an alternative. <br /> ƒif clear panels of any kind are in use, incorporate surface treatments to <br />make glass visible. See “exterior Glass” pages 20-21. <br />Clear barriers create a deadly hazard for birds these two birds were fooled by habitat reflections
