Saharan dust

South Florida has settled into a rather boring but typical wet season pattern following the spate of tropical storms which culminated in Elsa. We are also in the middle of the Saharan dust season. Dry air masses laden with dust have been coursing over from the African continent. This has the welcome effect of reducing the intensity of the tropical storms which spawn cyclones in the eastern Atlantic ocean.

Visits to nearby Chapel Trail Nature Preserve were not very productive. The high water levels dilute out aquatic prey and wading birds are free to forage over a much greater expanse. 

Often I can find a dozen or more Gray-headed Swamphens, but this morning there was only one:

A pair of Northern Cardinals foraged on the boardwalk for the fallen fruit of an overhanging tree:

The male cardinal perched on the boardwalk railing near an interpretive sign:

A male Anhinga, partially hidden in the spike-rush, dried his wings:

A juvenile Red-bellied Woodpecker searched for food on the trunk of a small tree:


White-winged Doves nest along the boardwalk:


Swamp Lily:

Brown Basilisk:

The Sarahan dust is said to stabilize the weather, which has been rather monotonous, with warm days and nights along with intermittent "pop-up" showers. This past week's forecast was remarkable (32.2 to 25.5 Celsius):

The dust can produce very colorful sunrises and sunsets. Fifteen minutes before sunrise this past Saturday morning, the unseen sun was reflecting off a pink mass in the upper atmosphere:

Within minutes, sunlight had illuminated the expanse of the dust cloud:

While the sky directly overhead was otherwise clear, storm clouds were lined up along the Atlantic coast to the east. The shadows of the tops of the clouds broke the rays of the rising sun. The rays reflected off the dust layer and converged over the Everglades on the opposite (western) horizon. The anti-solar rays were creating a "false sunrise," so I hurried to the lake to catch the reflections on the still water:

    1. @This N That-- Hi, Mollie-- the "false sunrise" occurs just before and during the first 10 minutes after sunrise. Before and for a few minutes after sunrise, the reflections do not reach down to ground level as the shadow of the earth is in the way of the sunbeams. Best wishes and thanks for dropping by!

  4. Hi Ken,
    finally I also read "why call me rosyfinch".That was really interesting. These rosyfinches remind me of our "Bluthänflinge" = Linaria cannabina. - Your photos are great as always.Today I am especially enchanted by the sunrises. Thanks for that.
    Herzliche Grüße – Elke (Naturdonnerstag)

  6. I met an artist who does stained glass art(a New Jersey girl in Texas -it changes the demographics of the state!), depicting birds.I referred her to your blog, because of the diversity of birds you have on your blog.Love the skies here, Ken! Hope you are doing well.
    Oh, before I forget, I changed my username from Jeshie to Emille (to resolve a blog problem). Have a great weekend!

  7. Wow, gorgeous sky images. The last two sky shots are my favorite. I miss the Florida lizards, I do not see many in Maryland. Your cardinal photos are lovely. Sweet captures of the Doves. The Gray-headed Swamphen and young Woodpecker are great sightings too. Thank you for linking up and sharing your post. Take care, have a happy weekend. PS, thank you for the comment and visit.

  11. We too are experiencing the African dust along the Gulf. Of all your photos and narration, I have to say the anhinga is one I've been wanting to see but haven't yet; this summer
    Enjoyed your post, and photos. Thanks for linking up this week at IRBB.

  15. The weather forecast, while monotonous, is consistent and not one that would make me happy, Kenneth. That said, it has been rainy and warm even in New England. As always, enjoyed the bird images, water lily seeing the beautiful sunrise that resulted from the dust.
