The Colorado Field Ornithologists organization maintains an email list service which allows the state birding community to post bird sightings and exchange questions and information about
Colorado
birds and bird conservation. To participate, anyone can visit their website at www.cfo-link.org/ and click on “Subscribe to COBirds” in the left-hand column of the homepage.
A person can subscribe to the list or merely read the digest posted on the website. A subscription is free and allows the holders to receive and post messages using their regular email software. The service is monitored to ensure that the proper courtesy and topic relatedness are observed.
