sightings. The exact route will be determined nearer to the actual date
based on weather and various sightings. A general idea about locations
would be Denver, Adams, or Weld counties. A general idea about target
birds will be raptors, waterfowl, and potential rare birds. Be prepared to
drive/ride more than a hundred miles, but hiking will be at most moderate.
Bring binoculars, scope, snacks, lunch, and plenty of water. We will
carpool in three cars and drivers will be reimbursed for mileage. if you
have walkie talkies, please bring them. They will be very useful when we
caravan. Register online or contact leader.
