Humboldt and Del Norte Counties offer top-knotch birding, and a suite of species that can’t be found in the rest of the state. Gull-billed Terns breed in south San Diego Bay, along with Black Skimmers and several other tern species.

It goes without saying that our three breeding species of mergansers in the United States are amongst the most brilliantly colored birds we have. Common , Hooded and Red-breasted Mergansers all breed here, but Red-breasted is the more northerly of the group. They don’t breed here, but winter strictly on the Front Range.
