Fort Jefferson - Dry Tortugas National Park

 Thursday May 18th

Great White Egret

The fully booked Yankee Freedom left its mooring in Key West around 8am for the 70-mile sail to Garden Key in the Dry Tortugas. Today was Monday May 8th and like me there were several birders aboard heading to Fort Jefferson on Garden Key to enjoy some special birding opportunities.

eBird Checklist - 8 May 2023 - Dry Tortugas NP--Garden Key - 36 species

In April and May, the Tortugas can be a magnet for migrating birds seeking respite from the long flight across the Gulf of Mexico and nearby Keys are also hosting breeding colonies for Sooty Terns, Brown Noddies, Magnificent Frigatebirds and Masked Boobies.

Other passengers are also finding the birdlife interesting, but we can add the fascinating history of the Civil War Era Fort Jefferson.  Then add the opportunities to do some snorkeling the waters around Garden Key. 

As the Yankee Freedom sailed west, we left Key West behind and would pass the Marquesa Islands and the waters were treasure hunter Mel Fisher had located the some of the wreak of the Nuestra Senora de Atocha and her riches.

On the sail to the Tortugas, I and several birds scanned the waters for any pelagic species. Dipped on spotted any of the expected Shearwaters. Mostly seen were frigatebirds and an unidentified jaeger. By 10:30 we had entered the boundary waters of the Dry Tortugas National Park and the boat's captain made a slow pass near to Hospital Key for the birders to get a look at and try to get photographs of the Masked Boobies nesting colony on the small sandy key. This small bit of sand is the only nesting site within the United States for the Masked Boobies. There were a few dozen present as well as around a dozen Brown Boobies. From here the air was filled with birds. Hundreds of Sooty Terns, Brown Noddies and Magnificent Frigatebirds have arrived here to nest on Bush Key.

We docked and exited the Yankee freedom to start our search for interesting birds. Had made acquaintance with some birders from Colorado, who were led by Nick Komar. Nick, I learned later was working on a Big Year and seemed to be having a great start. An interesting coincidence was that on my last visit here, I had made the acquaintance for with another pair of master birders from Colorado - John Vanderpoel and William Kaempfer, who had helped me with getting on my lifer view of a Black Noddy. 

Black Noddy

First headed toward the north coaling pilings looking for good shots of the Brown Noddies and sooty terns, plus the rare Black Noddies that rest on those pilings.  Got my tern and noddy pics but would have to go up to the top of fort to get the view needed to spot the Black Noddies. Which I was later able to do.

Bridle Tern

A trio of Bridle Terns were found near a closed off area at the concrete pad by the south pilings.  

Other sea birds seen included Rosette Terns, Royal Terns, Brown Pelicans and Laughing Gulls.

Inside the fort we found some of those interesting migrant birds. Common Nighthawk, Eastern Wood-Pewee, Eastern Kingbird, Gray Kingbird, Wood Thrush, Yellow-billed Cuckoo, a Great White Egret, Belted Kingfisher, Ovenbird, Cattle Egrets, a Green Heron, Bay-breasted Warbler, Indigo Buntings, Palm Warblers, Common Yellowthroats, Cape May Warbler, Northern Parula, American redstarts, Scarlet Tanager, Black-throated Blue Warbler, Blackpoll Warbler and Gray Catbirds. Had a few swallows too - Barn, Cliff and Bank were present.

We wrapped up our stay when the Yankee Freedom headed back to Key West around 3pm. Lots of tired folks after a day in the sun.
