May I introduce the propagule?

In April I was in Vero Beach, Florida for a bewitching week with friends. It is a barrier island, and the inland waterway is bordered by red mangroves Rhizophora mangle.

P1040475

Their name comes from their reddish stilt roots; the above-water sections help them breathe.

P1040397

These extraordinary trees and their roots provide important habitat for all sorts of fish, crustaceans and birds, including this American White Ibis,  Eudocimus albus, who is looking for crabs:

P1040339

Mangroves live in brackish water, and they have the most unusual reproductive system. They flower, like most plants, producing tiny inconspicuous downward-facing flowers:

P1040767

But instead of then producing seeds, they produce propagules, (a brand new word for me, sadly with too many letters to be very useful in Scrabble).

P1040769

These miniature plants stay attached to their mother plant while they grow a longer and thinner root:

P1040761

Eventually, they drop off into the water below:

P1040770

Once launched, they bob around vertically and drift with the tides and currents until they stick tip-down in the mud, and become a new tree.

The mangrove edges provide rich pickings for this Little Blue Heron, Egretta caerulea, foraging at low tide:

P1040603

Alone among herons, the pure white immature is entirely differently colored from this adult.

And in these lagoons there be manatees, which the early mariners thought were mermaids. To my delight we saw them, but not clearly enough to photograph, so this will have to do:

Florida may conjure up images of Disneyworld, but it still has many wild and beautiful places.  More next time.

“A great eagle with great wings”*

Compared to the Broad-winged Hawk of Maine, the Tawny Eagle of Ethiopia, Aquila rapax,  is of an altogether fiercer order, as his name suggests. His wingspan, at 190cm, is almost twice that of the broadwing, and at up to 3Kg he weighs about six times as much. I rather like his warm feathered breeches.

Tawny Eagle

He feeds on rabbits and other small mammals, lizards and insects, which he catches with his rapacious talons (visible above if you look carefully). He is also an opportunist, not above feasting on the carcase of a dead goat, and in fact carrion is a large part of his diet:

Tawny Eagle, on goat carcase

The Black-chested Snake Eagle, Circaetus pectoralis,  is a tad smaller, and highly specialized:

Black-chested Snake Eagle

 

 

Snakes are his preferred food, and he hovers before diving onto his prey (he is claimed to be the only eagle that hovers). During courtship, a pair will feed each other snakes in mid-air, something I would dearly love to see.

My last photo is aa juvenile African Fish Eagle (thanks to Ian for the ID), but even as a teenager it shows the power of those wings that inspired the poets: *A great eagle with great wings, longwinged, full of feathers, which had divers colours, came unto Lebanon, and took the highest branch of the cedar:” Ezekiel 17:3

DSC09324

I’ve just realized I have referred to all my eagles by means of male pronouns: unconscious bias pops up in the oddest places. To keep things real, I have not corrected my prose, but I am clearly not woke yet.

Broad of wing

Before I left Maine,  just down the road from the beaver pond, I saw this Broad-winged Hawk, Buteo platypterus, all fluffed up drying itself after a downpour:

Broad-winged Hawk

When it deemed its feathers dry enough, off it flew:

Broad-winged Hawk

Platypterus means broad-winged, and the aptness of the name is clear from the photo above. This part of the hawk’s name is shared with the sailfish, Istiophorus platypterus, and two flies,  Sciapus platypterus  and Diogmites platypterus . If it reminds you of the word platypus, that is because platypus means ‘broad-footed’.

These small crow-sized hawks hunt by sitting on low branches, watching for prey on the ground. They in turn are preyed on by larger hawks, like the Red-tailed Hawk.

Here is what they sound like:

“What’s in a name?” 

As I was sitting quietly on a log watching the muskrats, a male Wood Duck, Aix sponsa, flew in right over my head and landed in front of me. In the 20 seconds or so before he noticed me and took off in hurry, I managed a photo: he is in full breeding plumage, very splendid: *

Male wood duck in breeding plumage

The second half of the scientific name, sponsa,  alludes to his resplendent turnout, in the hopeful expectation of being the groom at a wedding.  His intended spouse,  however, was nowhere to be seen.

The next morning, more water birds.  These are Hooded Mergansers, Lophodytes cucullatus.

Hooded mergansers, females or juveniles

Another apt name: cucullatus is related to the word cowl, as in a monk’s hood. It even has a tonsure!

Hooded mergansers, females or juveniles

These two seem to be either both females or juveniles because the male would be more spectacular.

The next evening, a male Northern Flicker, Colaptes auratus,  flew in to the very top of one of the tallest dead trees.

DSC09259

Notice the bright yellow (auratus) underside of his tail, found only in the Yellow-shafted subspecies of the Eastern US. They have a varied diet of insects and fruit, nuts and berries, but 45% of their diet is ants.

This one was not feeding; he was on a different mission. He alternately called and then drummed on the very end of the branch, typical territorial display for the springtime. Unlike most woodpeckers, they largely feed on the ground, so the drumming is unlikely to be foraging. Here is a short video:

 

And then the icing on the cake, for me. This beaver pond and all the others on my land were bereft of beavers last summer, and I didn’t see a single one. But as I was walking away, standing right out in the open, I saw a giant muskrat…… no, a beaver, the creator of this magical place! Happy days.

Beaver

(I am slightly worried that the poor beaver has a porcupine quill stuck in his upper lip? But maybe it’s just part of his mouthful of vegetation.)

* PS: In Florida three weeks ago I saw this pair of wood ducks, high in a tree. They will nest up to 65 feet up. As you can see the closer female is relatively drab:

P1040749

They breed all along the East coast of the US, but in winter the northerners all move southwards, rather like Canadian retirees.

Back to the present, and the less exotic. Behind my house in Maine there is a small beaver pond, currently seemingly abandoned since the dam is not being maintained.  These ponds are scruffy places, full of dead trees, but they create openings in the dark forest that are home to all sorts of wildlife. All the photos in this and the next posting were taken last week on my pond. The small teepee-like pile of sticks, background, left of centre, is the old beaver lodge, and as you can see I had to take my photos from some distance.

DSC00170

There are two muskrats living in the pond this spring.

 

Muskrats, Ondatra zibethicus, are about a foot long, with another 10 inches of bare black tail.

DSC08952

At first glance they could be very tiny beavers, but the tail is quite different, round at the base and then flattened vertically:

DSC00286

They are living in the old beaver lodge, and they emerge to eat roots, rhizomes, shoots and leaves, which they wash obsessively first, before eating them delicately:

DSC09068

This video shows one eating, washing,  and eating its lunch, in their typical frenetic fashion:

 

They are feeding from a feeding station in the middle of the pond, exactly at water level, so that they can reach to wash their food easily, and are also safe from predators. If the water level goes up or down, they choose a new feeding station. They slide off to get more food, and return to the same spot for the next course. Their front feet are able to manipulate the food with great precision:

DSC09537

Their hind feet are much larger:

DSC09518

I suspect they have young in their lodge, because the next morning they were busily diving for vegetation, then taking it straight back to the lodge, instead of eating themselves:

DSC09492

A litter will have 4-6 kits, and they are born naked. When the mother leaves to feed, she covers them with shredded vegetation to keep them warm, so this may be bedding, not food, that she is carrying back. They are ready to live on their own by 4 weeks, and she may have 3 litters a year.

In the winter, muskrats gather in groups in larger lodges for warmth, and move around under the ice, making occasional holes through which to breathe and feed..

PS In its native North America the muskrat is doing fine, although it used to be heavily hunted for its long thick fur.

DSC09186

It was introduced into Europe for its pelt, but has now become a serious pest in some countries, where among other things it burrows through Dutch dykes, presumably creating jobs for little Dutch boys who use their fingers to plug the holes ….

PPS Ratty in Wind in the Willows, is actually a water vole. He is on the left below. He is about 2/3 of the length of a muskrat.

images-3

Kenneth Grahame describes Ratty thus:

“Dependable and thoroughly decent, with a fondness for impromptu picnics and impeccable taste in clothes, this twinkly-eyed country gentleman would take you out for a glorious day on the river before asking you, as the sun began to set and he draped his jacket over your shoulders, whether you’d care to have dinner with him next week.”

In 2011 readers of Country Life ranked Ratty second only to the gamekeeper Mellors in Lady Chatterley’s Lover as their favorite “lusty literary hero”.

Go figure.

 

The mother, the jewel and the clown

[The first photo is honor of US Mother’s Day tomorrow!]

Maternal love is not to be explained. This warthog and her baby are clearly struggling in this harsh arid environment, but their mutual gaze is every bit as loving as that of  Mrs. Bennett and her offspring.

Note the Red-billed Oxpecker looking on, oblivious

dsc08898.jpg

Beautiful the warthog is not, but Ethiopia has bejeweled wonders for the taking, like this Northern Carmine Bee-eater:

Other birds are almost comical:

Double-toothed Barbet

This is the Double-toothed Barbet, named after its unusual beak, seen here in close-up:

Double-toothed Barbet

The notches help it hold onto live and kicking uncooperative prey, like scorpions or frogs.

My last photo is blurry, because the camera insisted on focussing on the branches not the bird,  but this male Nile Valley Sunbird in his breeding plumage is so fine I thought I’d include him anyway.

The Fish Market: strictly for the birds

[If you only want to see the birds, they are mostly near the end of this post!]

There are two fish markets on Lake Awasa in Ethiopia, and they attract a rich melange of human life and wildlife, in a symbiotic balance that has probably changed little for centuries. The boats are skiffs:

DSC07542

And there are dozens of them:

DSC07398

The fishermen clean the fish with ferocious mini-scimitars and sell them to middlemen:

DSC07440

Who in turn sell to local buyers:

DSC07584The pelicans hang around hoping for discards:

Great White Pelican

The entrails are sold for “rich man’s dogs” to eat, but there are plenty left over that are cleaned up by the marabou storks:

Marabou Stork.

though this stork has clearly scavenged from something much larger:

DSC07491

The  half-wild village dogs chase the storks (unsuccessfully, and the storks are much larger than them anyway, their 12 foot wingspan is the largest of any living bird):

DSC07507

And they also scavenge the carcasses dotted around the shoreline:

DSC07576

On land there is a party atmosphere. Kids play soccer, though this goalie is rather unorthodox:

Marabou Stork. Goal.

At the back, stalls sell fish soup:

And in the back rooms , something else:

In the water, birds abound. A spur-winged goose:

And Hammerkopfs:

Everyone wins except the fish. As the population (both local and tourist) increases, overfishing is apparently taking its toll, and the catch is steadily shrinking,

P.S. Lake Awasa is part of the Great Rift Valley, It is an endorheic basin, meaning it is fresh water, but has no outlet (except perhaps an underground one), and instead it peters out into shallows and swamps.

P.P.S. Most of these photos were taken at the smaller and less official market. The high-end hotels buy from the other one, which is slightly (just) more hygienic!

Mountain Nyala: Shy giants

My final Ethiopian antelope weighs about 100 times more than my first, and is much rarer.

The Mountain Nyala, Tragelaphus buxtoni, my last and largest antelope from the Ethiopia trip, is found only in Ethiopia. Our first glimpse was a big male browsing in the distance: they can weigh up to 300Kg, and be up to 53″ tall at the shoulder, Their horns always have creamy tips:

DSC09648

The Bale Mountains have a montane woodland ecozone at around 10-11,000 feet, and that is where the shy, elusive nyala are most often found. As we walked, they were all around us, but dissolved into the trees when we got too close. So we had only tantalizing glimpses:

Mountain Nyala, endemic to Ethiopia

Until this closer encounter:

Mountain Nyala, endemic to Ethiopia

They are endemic to the Ethiopian highlands, with half the total population in the Bale Mountains National Park. They are considered endangered, and there are thought to be only about 2500 adults left in the wild.

They might well remind you of the kudu or the bushbuck with their grayish coloring and white markings, and you would be right, they are related to both.

PS The Ethiopian 10 Birr coin has a nyala on the back, demonstrating their significance to Ethiopians.

That dreadful Hartebeest

After a break from antelope, back to Ethiopia and a couple more, larger than the last batch …..

This elegant beast is a female Lesser Kudu, Tragelaphus imberbis. She will hide in thick brush most of the day and feed mainly at night. Males can be 41″ at the shoulder and weigh 108Kg, with spectacular spiral horns.

Lesser Kudu

For comparison, these are male Greater Kudu, Tragelaphus strepsiceros, in Zambia last spring. These males are much larger, 63″ at the shoulder and at 270Kg weighing more than twice as much as their Lesser brethren.

Kudu. "The Grey Ghosts".

There are only around 700 mature Swayne’s Hartebeest, Alcelaphus buselaphus swaynei, left in the world, and one of the remaining populations is in Senkele sanctuary, not far from Lake Awassa. The sanctuary is reached via a dirt road through a tiny village, and the village kids climbed precariously on the back of the bus for a fun but dangerous ride. Our worried guide tied thorny acacia branches to the back, which successfully dislodged them.

The rangers had burnt the dry grass to encourage new growth, and the herd had headed straight there for the tiny invisible green shoots.

Swayne's Hartebeest, endemic to Ethiopia

This mother spent maybe ten minutes cleaning her baby’s bottom. A mother’s love knows no bounds, but I prefer baby wipes.

PS Hartebeest were given their name because they look rather deer-like, ‘hart’ being an archaic word for deer, and the obsolete Afrikaans hertebeest means ‘deer-beast’. Males can weigh up to 200Kg, much larger than the Lesser Kudu.

PPS My title comes, yet again, from the Flanders and Swann song about the Gnu, since poems about hartebeest are hard to come by…

“G-nor am I in the least
Like that dreadful hartebeest”

PPPS You will be relieved to know that after today there is only one last antelope post still to come!

Strutting Tom

It is definitely spring. Outside my study window, in the mist,  a tom (male) turkey is displaying to his lady hen, who continues to preen, unimpressed by his splendor.

P1040208

Seen advancing from the front he is quite a sight, like a galleon under full sail. He has an enormous blue snood hanging down over his beak, a darker blue face, …. and bright red wattles. He puffs himself up, and drags his wings,  strutting his stuff, the Arnold Schwarzenegger of the turkey world.

P1040176

Meanwhile, she grazes on,  oblivious.

In 1784, Benjamin Franklin wrote to his daughter in support of the Turkey as national bird: “For my own part I wish the Bald Eagle had not been chosen the Representative of our Country. He is a Bird of bad moral Character. He does not get his Living honestly. You may have seen him perched on some dead Tree near the River, where, too lazy to fish for himself, he watches the Labour of the Fishing Hawk; and when that diligent Bird has at length taken a Fish, and is bearing it to his Nest for the Support of his Mate and young Ones, the Bald Eagle pursues him and takes it from him.

…For the Truth the Turkey is in Comparison a much more respectable Bird, and withal a true original Native of America . . . He is besides, though a little vain & silly, a Bird of Courage, and would not hesitate to attack a Grenadier of the British Guards who should presume to invade his Farm Yard with a red Coat on.”
