Subject: [BIRDWG01] Colorado Booby ID
Colorado just had its second record of a booby, found on June 16th & seen early again on the 17th after which it disappeared.

It was found in a tree out on the prairie in far SE CO. No water body even close.

There are several photos of the bird, which did take flight a few times, always coming back to land in an Elm tree. At one point it was on the ground.

We are trying to determine if this is a Brown Booby or Cocos Booby. Possibly not a full adult. Any help would be appreciated.

You can view the photos of the bird here on these 3 checklists:
