One of my family art and nature walks takes place every week at Corporation Beach in Dennis. It is a great place for both families and exploring tidal pools and even though yesterday was a cloudy day the tide was almost out and we had a great group.
Wellfleet Bay Wildlife Sanctuary and it wasn't long before other birders came along to confirm the ID.
Sibley bird book of the juvenile brown booby, a bird much more likely to be seen in the Caribbean than in New England. The other bird seen recently was actually seen in Maine and looked to be an older bird than this. Perhaps they got blown up this way in one of the recent storms we had.
You can learn more about the brown booby from this site and yes, this bird has a funny name. I do know this bird stayed at the beach until at least dusk and it may still be there this morning. If you do not have a Dennis sticker you will have to pay to park at the beach.
