DO
✓ Keep quiet, says R.J. Pautsch, president of the Boulder Bird Club. Sudden, loud noises can scare skittish birds away.
✓ You don’t need to spend a lot, says Peter Burke, a board member for Colorado Field Ornithologists, a nonprofit promoting the conservation, study, and enjoyment of Colorado birds. Look for a pair with a weather seal at the Front Range Birding Company’s Boulder or Littleton location.
