Gulf Islands National Seashore - Perdido Key Backpacking Trail

On May 28th, I woke up before the sun and headed out toward Perdido Key, west of Pensacola, Florida. I had two goals: watch the sun rise and hike the backpacking trail to the end of the island and back. The trail is considered one of the best for backpacking in the country and offers primitive camping for backpackers and boaters. The nice thing about it is that there is no car access, which, were it not for the skyscrapers in the distance, would contribute to a feeling of remoteness.

A ghost crab at 5am. When the gate finally opened at the Perdido Key branch of the Gulf Islands National Seashore, I rubbed my eyes and drove down the narrow, dune-flanked road. The road was crawling with crabs and I did my best to avoid them, though it was clear that the ranger who drove in before I did was less careful. I parked and began my pre-dawn stroll (or stagger) down the lagoon-side of Perdido Key.

I often enhance my pictures with colour corrections to try to make them more true to the original colours or more artistic. However, I wanted to give you the rising sun the way my camera saw it without any alterations (except some cropping). So all these sunrise pictures are unedited.

Golden shafts of light announce the suns approach, just below the horizon.

And there he is.

The sun rises over the city of Pensacola. Zooming in really brought out the reds. I didn't edit this picture or change the original colours from what the camera captured.

Zooming way out brings out more gold and blue colours.

Once the sun peaks over the horizon, the ghost crabs head for their burrows.

There were giant colonies of nesting terns all along the trail and, occasionally, to avoid bombardment and disruption of the terns behaviour, my path was diverted.

A smashed turtle shell seems to tell a sad tail of boat-testudine collision.

The crabs are fast but can be caught if they are blacked from entering their burrows. Of course I release them unharmed and never keep them from their burrows for more than a couple of minutes. Once upon a time, these crabs were sought after as popular dissection specimens for schools. I don't know that there are enough of them around any more to be as much use in that regard as they used to be.

Nearing the end of the island, the ancient ruins of forts used during World War II, the Civil War, and others can be seen crumbling into the dunes.

Needle rush, greenbriar, and touch-me-nots were among the unpleasant plants encountered.

A young pelican lies decaying were it fell. Many young pelicans are killed by their siblings before ever leaving the nest.

A Rare Treat at Johnson Beach

Field Notes from November 15, 2015

Provided I can get enough of my grad schoolwork and housework done on Saturday, I sometimes spend a lazy Sunday afternoon birdwatching. Of course, if the opportunity arrises, I can't help but do a little herping and bugging to the side.

There were patchy clouds in the sky and some growing thunderheads to the west threatened rain at Johnson Beach, Gulf Islands National Seashore. If the sun was shining, it was warm, but if the clouds covered its power, a cold wind chilled the ground. It would seem that this chill was too much for one anole (Anolis carolinensis), which lay dead and crispy on the leaflitter underneath an Ilex vomitoria plant. I stumbled upon the grim spectacle at the same time as a large, 1.3-meter black racer (Coluber constrictor) noticed the fried lizard. Of course, I noticed the snake before I even realized that it was eyeing up frosty leftovers. I started snapping pictures immediately and documented the whole process from mouth to stomach. Apparently, racers are not above scavenging.

I noticed an elderly lady walking her pug down the boardwalk as I crouched, observing the process. I motioned for her to approach slowly but it was too late. The snake moved off into the shrubbery and she couldn't see it in the shadows of the Ilex. Farther along the boardwalk I met her husband. He was a little more enthusiastic about the prospect of seeing a snake than his wife and I took him over to where I'd spotted it before. Of course, it was long gone.

Anyways, the purpose of this stroll was to birdwatch so I'll cut to the chase.

Mergus serrator - A few red-breasted mergansers were fishing in Big Lagoon, on the north side of the island.
Some tracks in the dunes may indicate the presence of the northern bobwhite (Colinus virginianus).
Gavia immer - There were a couple common loons in Big Lagoon and one flew overhead on the Gulf side.
There was a possible Podiceps (grebe) on the Gulf but I only got one fleeting glimpse before it dove and I never saw it resurface.
Pelecanus occidentalis - Several brown pelicans flew casually over the island.
Ardea herodias - A several great blue herons were spotted either fishing in the shallows of Big Lagoon, strolling among fishermen on the Gulf side, or resting among the dunes. One even walked across the road in front of me, apparently unafraid of my vehicle.
Charadrius nivosus - It was a little challenging for me to identify this one. At first I thought it was a semipalmated plover (C. semipalmatus) but the head patterns weren't quite lining up. Then I noticed the breastband wasn't complete and I knew it couldn't be the semipalmated. I think this may be my first personally confirmed record of the snowy plover.
Tringa semipalmata - The willet is always present at any beach on the Gulf, or so it would seem. I spotted several of them but I know I ignored at least a few others.
Arenaria interpres - One ruddy turnstone was chasing waves on the Gulf side.
Calidris alba - I know for sure that at least half a dozen of these birds were on the Lagoon side but I didn't take the time to identify every little sandpiper or peep that I came across. There could be other species present.
There were certainly many gulls around, probably Leucophaeus atricilla (laughing gull), but I didn't focus on gulls.
Thalasseus maximus - A flock of about half a dozen royal terns flew overhead, following the shoreline on the Lagoon side.
Columba livia - One rock pigeon near the public beach access.

Mimus polyglottos - A common sight anywhere in Florida, I spotted at least a few northern mockingbirds at the shrubby, west-end of the park.

Setophaga coronata - Yellow-rumped warblers are common in most Florida habitats. I identified a couple of them for certain, though there were likely many more.
Melospiza melodia - A pair of song sparrows were in the shrubbery in the dunes. I saw other sparrows as well but I couldn't identify them with certainty.
