Ocean Bounty Brings Solitary Birds Together
Walking mornings along the beach I encounter, one after the other, solitary sandpipers, called Willets. Before encountering this group, I noticed massed Black Skimmers feeding in the surf and, on the beach, a single, tiny (1/8th of an inch) fish that I scooped up and returned to the surf. My surmise is these several days around the full moon, fish were being birthed and swarming to provide a bounty that brough these solitary Willets together.

Subcategories of Twilight and more
Use your pinky finger to apprehend the sky dome. Imagine yourself at sea, out of sight of land, on a calm day. Keeping your arm extended, place your pinky-tip on the horizon due east, raise your arm directly overhead. The average sized pinky-tip will have spanned 90 of its lengths. The distance measured from the horizon to directly overhead, the zenith, is 90 degrees of sky dome, about one pinky-width per degree, one-fourth of the entire 360 degrees of sky around your spot on the globe.
The apparent width of the sun disk from earth covers 1/2 degree of sky dome. The disk center point moves 15 degrees per hour (360/24 = 15). Using these facts to estimate time to sunset is relatively straightforward. Estimating time to dawn from the sky is more difficult. This graphic, “Twilight-dawn subcategories,” is a way to grasping what happens. Your position on the earth globe affects the experience. For example, at northern latitudes above 60°34′ summer nights never become darker than civil twilight because the sun’s midpoint never drops lower than 6 degrees below the horizon. Civil twilight lasts all night long summer times in parts of Sweden and Finland.
The date-time stamp on the first photograph of this series is 6:46:23 am, Cocoa Beach sunrise for February 1st was 7:09:40, 00:23:17, 23.283 minutes in decimal notation, later. This duration divided by 60 minutes in an hour and multiplied by the sun’s apparent velocity across the sky (15 degrees per hour) and minus the .25 degree between sun’s center and disk edge, gives the sun’s center as 5.57 degrees below the horizon: this is a photograph of the sky a minute or so after the sun passed civil dawn into civil twilight. I am not more exact because this calculation does not account the deviation of the sun path from due east at this latitude, lengthening civil twilight duration by almost a minute.
The following photograph is time-stamped 7:05:06, 4.567 minutes until sunrise, sun center is just below the horizon, setting the dark clouds of the previous photograph fleetingly on fire.
Sunrise has passed in the following photographs, obscured by clouds and making for a great light show. Enjoy!!

unflappable lady hand feeds seagulls
When Pam read my post “Black Skimmers Feeding” she asked, “Where is the photo of resting Skimmers?”
To answer her question, I looked through Cocoa Beach photographs and discovered I did NOT capture the Skimmers resting. Instead, here are a related species, the Royal Tern (scientific name: Thalasseus maximus), whose behavior is similar in that it exclusively feeds from the water. There was a wind that morning and these individuals face into it. These birds are, from a human point of view, well behaved, unlike the opportunistic gull.
I searched around the web for identification of this gull without success.
It dines on a dead fish washed up by the surf. In my previous posting I used the word “grifting” to describe gull behavior, again this is from the human point of view. Gulls are notorious for stealing food from unwary beach goers, brazening walking over to unguarded chips (any kind), for instance, grabbing them and flying off. If the chip stash is large, this sets off a nasty feeding frenzy when tens of gulls swoop in and grab.
Here is a series of photographs, demonstrating this behavior.

The dawn flowed over Cocoa Beach as a lady attracted a crowd of hungry gulls, reminiscent of scenes from Hitchcock’s “The Birds.”
She is obviously an experienced gull feeder, unflappable with a steady hand
She had come to the shore at dawn for a photo shoot. Her male companion (husband?) was there with a camera.
Pam and I were there for the dawn, me with the Sony camera.
At first, I stood there amazed at the spectacle. She was in such control of the situation, not a victim, more like a lion tamer.
Then, Pam said, “You have to get this.” And I did.
Images of Newlyweds on the beach
With grandchildren in the Miami Area and a sister in Daytona Beach, Florida was on my mind this morning and memories of this beautiful experience on Cocoa Beach came to mind. After an eventful day touring the NASA launch control center, Pam and I took an evening walk during the golden hour, me with camera in hand.
Full in expectation of catching the passing scene with lots of shot I set to full size jpeg mode using a Sony Alpha 700 dslr with a DT 18-200mm f3.5-6.3 lens. The light was exceptional, so I did not expect much post production work.
My first impression was of the line of cruise ships heading south from Port Canaveral, the starboard side lit perfectly behind human denizens of the Cocoa Beach shore, in full enjoyment mode. A synergy of the images struck me. I took a few experimental shots then, as we progressed down the beach front this unusual tableau came into view.
Pulling back the focal length a bit the reason for the bride and groom on the beach is clear.
The session proceeded smoothly and professionally, it was a pleasure to watch. I felt no compunction for capturing these private moments on a public beach, the transcendence of the images reflect well on all participants.
Pull back to capture the entire environment.
Enjoy!!!
