Records Not Accepted By Committee

"Not Accepted" often brings a strong reaction from observers when they view the role of the CBRC as determining the validity of a sighting.  There are many reasons for not accepting a record, not the least of which is not meeting a standard of proof of "beyond reasonable doubt" when adding a record to our knowledge of Colorado birds.  Other records may have plenty of evidence to establish the correct species, but to date there is no evidence of natural occurrence or established populations.  Although the following records have not been accepted, the information has been archived and any of them may be re-opened for review in the future if so warranted.
