Wild African Predators and Their Cousins In Florida

Feature image is a pride of Cheetah (Acinonyx jubatus) including female and her three cubs in Kenyan scrub.

Typical daytime lion setting with an ATV trying to navigate around them. We passed them several times during the day and they never moved. 

Lions spend a remarkable portion of the daylight hours sleeping. I saw this typical behavior in the Florida Naples Zoo but I didn’t expect to see it so frequently in the wilderness of Africa. I expected them to be walking about and hunting and / or engaged in group activities. Seeing them sleeping up to 20 hours per day was a rude awakening. During the best daylight hours where photography would be easy, these critters were usually completely out of it. They would be sleeping in the roads and pathways without any care for traffic trying to pass. They were communally grouped, sleeping together among family members. Occasionally, they might be seen finishing off a meal from last night’s hunting but in general they were boring subjects

In the twilight hours, however, with the sun just at the horizon, the scene was dramatically different. Despite the near darkness, fog, and distance I was able to see the spine-chilling hunt of the packs in action. The pursuit could have been taken from a professional soccer coach’s play book. Each pack member had their position to play – scouting, blocking, hunting, and a final charge for the throat. Without team play all 16 lions would go hungry. 

When visiting the local Naples Zoo, I imagined an animalistic sense. It was as if the captive animals knew the truth of their sheltered, human dependent relationship. At the zoo the animals pace around in their enclosures. There is nothing to hunt. There is no territory to defend. There are no mates to pursue. No families to care for. See out previous blog on the Naples Zoo. This is in contradiction to the animals seen in the African wilderness. There they were busy surviving as hunter, prey or both. On safari the animals are indifferent to the viewer. It is a sense that the people are not there because they are in a vehicle. The vehicle was of no importance. It was simply a noisy passing distraction. 

From our nearly three-week visit, several species stood out as apex predators. These included lions, leopards, cheetahs, wild dogs, crocodiles, and eagles. Each of these meat-eating animals is magnificent in color, shape, skill, and speed. These animals need a large area under their dominion. The area could easily range from 20 to 400 square kilometers. Lion prides and dog packs hunted using carefully laid out strategies and roles. Of the cat and dog, it is difficult to suggest that one is superior to another as their hunting behaviors were very similar. What do they do the rest of the time? They sleep and just hang out.

African black panthers have not been photographed in 100 years until recently. The term black panther is most frequently applied to black-coated leopards (Panthera pardus) of Africa. I did not see this African animal.

melanistic color variant of the African leopard – was filmed in Lorok, Laikipia County, Kenya, on remote cameras set up as part of a large-scale study aimed at understanding the population dynamics of leopards. Dramatic night photos of this are available at the link mentioned here. (*)

Murphy is a Floridian rescue greyhound (Canis Lupus Familiaris) He sleeps most of the day. He might be able to survive for a day or two on the African savanna before finding a friendly human. He is an excellent hunter and can outpace a cheetah on the long run, clocked at 45 to 50 mph for at least 275 yards and 35 mph for 7 miles. The best African animal survivors are pack animals, and the domesticated dog has lost this complex behavior instinct important for family group survival. 
Wild dogs ( Lycaon not Canine), Maasai Mara, Kenya. Just rising from their nest to begin their hunt.

There were some Florida animals in the wild that were directly comparable to those seen in our African safari. These are birds and reptiles. The two apex predators that I saw most often were the Sea Eagles (Osprey) / African Sea Eagles as well as the Florida alligator/African crocodiles. The lizards spend most of their time cruising the water and  lying on the shore waiting and watching for an opportunity to eat. The birds, on the other hand, were busy and exceptionally photogenic.

Fish Eagle (Haliaeetus vocifer) Okavango Delta, Botswan. Going out to fish in the near by river.
Florida alligator (Alligator mississippiensis) waiting for a raccoon or turtle.
Kenyan crocodiles (Crocodylus suchus) waiting for wildebeest

No doubt about it. The birds worked throughout the day. The African Sea Eagles and their cousins, Florida Osprey, were constantly searching and bringing fish back to eat or to feed their brood in the nest. The surprise was to see that these unfettered bird species which are different species but so similar in their size, behavior, and call.

We will spend additional time describing these bird and cat predators. The Zoo is wonderful to visit and see these animals. It is a good place to sharpen your camera skills for animal portraiture. It is a great place to show the real-life animals to children. Zoos are excellent for research and help preserve endangered animal stock. In the wild these same creatures are daily interacting with one another and their environment. There are no barriers separating them. They all struggle for survival. They pay no attention to people. If you want real understanding of the life in a giant working and evolving ecosystem you need to go out and experience it. We live in the Everglades reserve area. This is one of our National and State treasures. If you simply drive a few miles and walk into the Florida reserve area with a guide you may have an experience similar to ours in the Okavango Delta of Botswana

    That was a fascinating article! I had no idea that those animals slept most of the day. Thanks for sharing.

      When visiting the Zoo I have a better appreciation why the animals are sleeping and just hanging out most of the time. It is just their nature to do so.

Tree Blooming Near the End of Summer

With this season we are nearing the completion of the annual cycle of the flowering trees before departing to Africa and Europe. We started this series in the first week of December of 2021 with Trees of Christmas. It has been a remarkable adventure to learn about and collect images and data for the flowering trees in South West Florida (SWFL). Nearly every hue and chroma of the rainbow has been represented in the flowers ranging from deep indigo to brilliant intense reds. See more details about them on our Epicollect5 website. The trees all have exotic origins from Europe, Africa, India and Central/South America. Perhaps we will find some similar trees in Botswana’s Okavango delta and the plaines of Kenya. If all goes as planned we will be there in August of this year.

The featured image is a Purple Glory.

Many of the Blooming Trees of Late Spring are still in flower and in part include the Royal Poinciana, Jacaranda, Plumeria, and the Mexican Tulip. Missing is the Bauhania which had been blooming since Christmas. It has, at last, given up the last flowers.

Royal Flamboyant Poinciana. Still one of my favorite flowering trees, it is repeatedly throwing out new blossoms and filling the neighborhood with a spectacular display of color.

Here are the last of the newly blooming trees which I found on my last walk about.

Pride of India (Langerstroemia Speciiosa). Native to South Eastern Asia including India.
Australian umbrella (Scheffera actinophylla). An evergreen tree native to Queensland Australia. Toxic to dogs and cats when eaten or touched by the sap.
Not as big as a standard tree the Princess flower tree is also known as Purple glory. It has some of the most intense purple flowers.
Purple glory (Pleroma semidacandrum) is native to Brazil.

All of these blossoms are found less frequently as the summer progresses. The neighborhoods and wilderness are definitely less colorful. The remaining flowers will probably last for two months. We will look again after returning from the safari. The interesting plants now include palms and pines. Next year adventures will focus on the palm trees more closely showing the varieties of colors, leaf patterns and fruiting bodies. We will finish the series by making the autumnal blossoms posting during the end of October.

After returning from Africa I hope to post a number of articles comparing the landscape, water features, plants and animals to those in SWFL. I expect these to be very interesting and hope that you are also interested.

To Tree or Not to Tree

Is a palm tree not a tree? In categorizing plants and animals for the Everglades Ark Epicollect5 data base I was conflicted in assigning the characteristics of trees to palms. I have called them palm trees forever but they really look different from oak, olive or other trees. Checking out the definition of a tree resulted in an ambiguous answer.

Featured image: In a spin about palms

Definition of tree: From a technical standpoint, palms fit American Forests’ current definition of trees, as they are woody plants with an erect perennial stem or trunk, at least 9.5 inches in circumference at 4.5 feet above the ground. They also have a definitively formed crown of foliage and a height of at least 13 feet. 

This still didn’t satisfy my curiosity. I still wondered why they were so different. Here are photographs of tree aspects to show the physical differences:

Tree landscape view

Leaf patterns

Central vein with alternating branched secondary veins
Radial symmetry of straight palm leaves with straight unbranching veins

Photomacrograph leaves

Here is a demonstration of reticular veining ~35X
All straight, parallel veining without branching ~35X

Photomicrograph of leaves

Branching veins becoming progressively smaller as they branch ~600X
Straight, parallel veins even at the microscopic level at ~800X

Common biology of both di and mono cotyledonous plants. Both have chloroplasts for metabolism and stoma

Stoma are more randomly disbursed in the leaf surface. The stoma are on the underside of the leaf in the dicot group ~800X
Xylem and phloem circulation and stoma for respiration. The stoma are on the upper side of the leaf ~800X

Tree roots

Broad and deep root system of dicotyledon, olive tree adjacent to monocotyledon palm.

Tree cross sections

Tree rings show annual growth and suggest weather conditions. Specialized bark system.
No rings and no mechanism to repair. Bark is a remnant of leaf system.

Tree behavior to injury

Progressive but not yet complete healing of dicot tree

There is no mechanism for healing in palm trees.

Flowers

All dicots have five petals to their flowers

No petals but other monocots have three petals

Here is a list tabulating differences in the characteristics between the tree types.

Aspects:Palm True tree
Rootsshallow multiple small distributeddeep, branching with tap root
Trunkthe trunk is actually the stem which bendsthick, rigid
Branchesno branchesmultiple arborizations
Leavesveins begin at the base, run parallel to the length of the leaf, stoma on upper leaf surface central veins with multiple arborizations to leaf periphery, stoma on lower side of leaf
Outer surfacestumps of old growth leaves, no structured interior wood specialized bark covering wood

Comparison of plant distinguishing characteristics

A palm tree is really a palm grass.1 They are monocotyledons. Genetically they are similar to other grasses like bamboo. They are resistant to storm damage fracture because of their lack of a woody interior structure but are more subject to uprooting because of their shallow roots.

Grasses are flowering plants that are members of the monocot class that also include corn, rice, lilies, orchids and palms. Now that I understand what a palm is I can more freely post palm types, flowers and fruits. Later I will show the microscopic view of tree anatomy pointing out differences between monocots and dicots.

This subject opens a wide spectrum of ideas regarding plants. We have already broached the idea of cotyledons. There is much more to explore including the microscopic examination of cross sections of plants and their appendages or stems, roots and flowers as well as angiosperms vs gymnosperms and the role of sexual vs asexual reproduction and seed development.

The micrographs shown here are all done with simple direct bright field and transmitted light. Just wait until we get into cross sectional, stained, transmitted plane, and polarized light illumination!

The Epicollect5 database will be modified to reflect this altered view of classification.

Storks and Spoons

Roseate Spoonbills (Platalea ajaja) and Wood Storks (Mycteria americana) share the limited water in the marsh during this dry period before the monsoon season. They both feed in the shallow marshes but do not compete for the same prey. The Spoon Bills are bottom filter feeders while the Storks pick up insects and small fish. The Spoon Bills spend much more time preening than the Wood Storks. I find this particular group appealing because of the stark difference in the feather colors and behaviors of the two species. The spoonbills are so much more flamboyant than the severe storks. Both are iconic birds of SW FL. The feature image is an overview of the flock of birds including the spoonbills, wood storks as well as snowy egret and maybe a blue heron.

“I hope you don’t mind me drying my plumage here.” I emphasized the visual line of interest here.
“There! Now I’m all clean and dry. Arn’t I beautiful?” I really like the reflections in the water in this image.
“Eeeks! Goodness Chickie! Can’t you do that somewhere else? I just got done doing my feathers!”
At last some peace and quiet in this stand of isolated mangroves that has water at this period of high tide.

With diminished water and a protracted drought, water dependent birds are crouded together. These conditions make photography interesting. The birds may be more remote and thereby technically more difficult to photograph. The more compact group with more variety improves opportunities to observe bird behavior. The best approach I had for the group image was still at a distance of 150 meters. The image was just at the limit of the hand held 300mm lens that I had in my bag. I casually followed one bird through the afternoon and in the late in the day it sought an isolated area away from the flock. The fill-in-flash picked up the brilliant colors.

Make a comment: Which bird images do you prefer, roseate spoonbills or flamingos?
