dr. christine sheppard that describe the hazards of birds in a built in environment and i spoke about birds eye's that have been evolving for vision during flight. birds fly into glass defending a territory or when attempting to reach vegetation not reflected in or through the glass. the standards offer alternatives and realistic measures to minimize our prevent negative impacts to birds. one recommended change is to reduce the size of the location related hazards for the urban bird rescue acres to 1 acre. this would protect areas adjacent to open space. these standards cover sliding glass when technology and other structural elements. a variety of methods to minimize the hazards are provided. the information is based on the best available science and can make cities safer for birds. please adopt the standard. >> thank you.
