American Bittern is not normally considered rare and on the RBA.
But the recent report of one in Archuleta county was a first for the
county so I included it on the RBA. When a bird is a new county
record and I know it, then I include it on the RBA and indicate it is
a country record. We do have county listers. Another recent county
record is Black-chinned Hummingbirds in Gilpin County. We may have
another of Eastern Phoebe in Rio Grande but I will have to check on that.
