Bird Watching at Dry Tortugas National Park

Birdwatching enthusiasts would know the unique possibilities that exist only in the remote island oasis of Dry Tortugas. Situated in Florida near the Gulf of Mexico to the far west of Monroe County, roughly 70 miles west of Key West, Dry Tortugas National Park forms the southernmost point in the continental United States. Juan Ponce de Leon discovered the keys in 1513, then named after the abundant sea turtles, Las Tortugas. The "Dry" was subsequently added regarding the lack of fresh water. The Tortugas is formed of seven keys: Bush, East, Garden, Hospital, Loggerhead, Long, and Middle keys.

Major Attractions at Dry Tortugas National Park

Probably one of the most remote locations in the country, the park is only accessible through ferry, boat, or seaplane. However, the trip is worth the while as this national park offers avid bird watchers the rare opportunity to observe bird species that do not occur anywhere else in the whole country.

The 100-square miles of Dry Tortugas National Park is basically seven small islands in about 90% of the clearest, bluest waters. The park's central features include its picturesque geological formations like the superlative coral reefs and sandy shoals and the abundant marine and avian life. The park holds one of the most historically significant structures, Fort Jefferson, located on 14-acre Garden Key, the second-largest island in the Dry Tortugas. The park is a wild tropical dream location that offers a wide range of water-based activities like swimming, snorkeling, geocaching, fishing, paddling, and diving along with birding, anger-guided tours, wildlife, and historical significance.

Bird Watching at Dry Tortugas National Park

The water paradise that is Dry Tortugas National Park is home to a diverse range of marine wildlife and attracts numerous varieties of birds throughout the year. The key feature is the range of Neotropical migrant species that venture to the park in spring and fall when it comes to birding. In addition, the park provides a suitable nesting ground for many Caribbean vagrants like the White-tailed Tropicbird, Red-footed Booby, Black Noddy, Ruddy Quail-Dove, Bahama Mockingbird, and Yellow-faced Grassquit. More than 300 native bird species have been recorded inside the Dry Tortugas National Park boundaries.

The seven keys are a critical nesting spot for Sooty Terns and Brown Noddies and together form the only regular colony inside the continental United States for both species. !n 1988, the Magnificent Frigatebirds of the Marquesas Keys colony shifted to Long Key, and by 1990 all birds settled at Tortugas. Masked Boobies began nesting on Hospital Key in 1984. Currently, the Tortugas are the only nesting site for Magnificent Frigatebirds in the United States.

The latest bird list for Dry Tortugas National Park contains 299 species. Most of this concentration is formed of transients or strays, present only during spring and fall migrations rather than permanent residents. Therefore, the best time to birdwatch in the park is when northbound migrants arrive early to mid-February. The spring migratory population peaks during April through mid-May, with more than 200 species passing through.
