THE DRY TORTUGAS ~ Trip Report
|
Day 1 / April 25 – Key West |
After lunch we resumed our watch as we approached the 7 islands that make up the National Park. East Key, Middle Key and Hospital Key, all narrow elongated sand islands, were in succession. One of the few markers that survived the onslaught of hurricanes in the fall of 2005 produced 3 Brown Boobies, including one adult. This was also the time that we first got our introduction to the seabirds that nest on the islands. Oodles of Brown Noddies and Sooty Terns made frequent forays back and forth to Bush Key while Magnificent Frigatebirds effortless graced the skies between Garden and Long Key, where they nest.
While the women opted to cool off by going for a refreshing swim off the back of the boat, the men scanned a heavily denuded Bush Key, though surprising still in full use, from the top of the fort. We came across a preening Black Noddy near the top of the dead bush line, which allowed for a great comparison with its close neighbor and relative the Brown Noddy, which nest in the low shrubs. However the was a short lived disappointment when it took off only to return within 5 minutes. Unfortunately by the time the ladies had made back to Garden Key by zodiac and reached the top of the fort, it took off again and never returned.
After a couple of hours around Fort Jefferson we boarded the Tiburon for the short ride over to Loggerhead Key. By the time we reached the island a weak, basically unnoticeable front had come through and the winds had shifted from the south to the north west. After Richard dropped us off at the north western end of Loggerhead and we had our fill of checking out the various ingenious Cuban rafts that had made it to US soils over the passed 3 months, we began to work our way through the sea oats quickly locating a very cooperative Short-eared Owl, the golden Caribbean race known as the ‘Arawak Owl’, after the indigenous Indians of that region. The island was really devoid of birds on this morning with the exception of a pair of Shiny Cowbirds that Debbie found hunkered down on the support beam of the porch of one houses; a juvenile Broad-wing Hawk; a couple of Bobolink and Mourning Doves and a Northern Waterthrush. Returning to the boat we had lunch while still anchored before heading to Hospital Key.
The Masked Boobies on Hospital Key were rather subdued today. Though we were able to get in close to view them, they were very quiet and we missed out on hearing the females grunt and males whistle. The number in this colony has grown each year that I have been coming here and we counted over 60 including 5 chicks of various ages, though all still with their downy feathering. At one stage we had about a dozen birds take off and circle the Key seemingly just to stretch their wings before landing again. We did get to see a couple of groups one consisting of about 9 birds well out at sea no doubt going on a feeding foray.
We spent the remainder of the afternoon on Garden Key, where we quickly joined the Wings group and all other birders that arrived on the day boats to look at the Black Noddy roosting on Bush Key, which meant that the whole group had now seen it – hooray! – but not after painstaking work to figure out exactly where it was in the tangled brush. The front actually bought in some birds that were not here during our morning walk through the fort. Tennessee and Yellow Warbler were quickly added as were a pair of Scarlet Tanagers. Noticeable was an increase in redstarts and magnolias as well as thrushes with Gray-cheeked, Swainson’s and Veery all seen well. Bob found a Spotted Sandpiper along the wrack line by the North coaling dock and a couple of Whimbrel’s were on the South coaling docks with a handful of Royal Terns and two Black-bellied Plovers. Most of us opted to sit at the water fountain to see what came in. Along with a steady parade of warblers, there was a female Indigo Bunting and a Dickcissel.
During the late afternoon and early evening, when the light is magical, we all piled into the zodiac with Richard at the helm and slowly made our way towards Bush Key to get close looks at the two nesting species and also see some of the dark juvenile Sooty Terns that were now wondering about on their own. It’s hard to image that once they are able to take flight that it’ll be 5 years before they land again, likely returning to the same spot to breed. Heading towards Long Key, we encountered one of those magical moments, one which I had never witnessed before, as sooties and noddies proceeded to fly right over our heads in droves as they circled back to the colony.
As it got dark and under a light cloud cover, though some stars and Jupiter were certainly in full view, Peg, Bob, Debbie and Kathi joined me in walking around the moat. It was not the most productive of walks compared to some we have taken, but did included fantastic close looks at a huge Starfish and Spiny-tailed Lobsters, one of which would have made a great feast for a large party. The tail end of a Green Moray Eel was a teaser and we got to see corals, sea fans, sea cucumbers, Spiny Urchins and a quickly retreating Bristle Starfish. But, where were all the Upside-down Jellyfish?
The winds were firmly out of the North West all night and we hoped for a decent fall out, but with the exception of larger numbers of thrushes, cuckoos and swallows including Banks and Cliffs, the warbler numbers never materialized.New species this morning included Eastern Wood Pewee, a female Orchard Oriole; male Indigo Bunting; Northern Waterthrush; a Black-whiskered Vireo; a likely (only because of a brief look at the underbody) Canada Warbler; a tired looking Yellow-throated Warbler of the albilora race, and an exhausted Ovenbird. Two male and a female Bobolink were still around and we got unbelievable looks at the Short-eared Owl that eluded us at Garden Key yesterday, as it flew around the parade ground. |

The journey back to Key West began a little rough as we had choppy 1-3 seas, but shortly after we passed Rebecca Shoals they began to smooth out and the remainder of the sail was very pleasant. The birds, unfortunately, were few and far between with only a couple of Brown Boobies seen early on. By the time Key West was in sight Atlantic Bottle-nosed Dolphins and Loggerhead Turtles had outnumbered birds, and there were only 2 of the former! It took us until the last marker before the tip of Key West to locate Roseate Terns. A group of about a sixteen was resting along with half a dozen Sandwich and a Royal Tern, which allowed for wonderful comparisons of size and structure.
A great surprise and a most enjoyable way to end the trip was having a Manatee swim right up to the stern of the boat and take the water hose in its mouth to get a drink of fresh water. Richard jumped in with his underwater camera to film it and Tim soon followed, as we all took turns in reaching into the water to stroke this most docile of mammals. By nature they are naturally curious, and there was plenty of evidence of its unfortunate encounters with propellers, with scars of various sizes on its back. In spite of this, this was a wonderful encounter with nature that everyone relished.
