Blue Springs Manatees

High on our agenda for our Florida trip was a visit to Blue Springs, a bit west of Orlando.  This is a classic limestone (karst) spring, carved out by upwellings of sweet water.  We devoted our last morning to it, as a sweet cherry atop the luscious sundae Sunday of our trip. It was cold and foggy when we arrived, making us envy the manatees stacked like cordwood in the pellucid 72 degree water of the river.  My first wild manatees, anywhere. Yes, I'd seen the Amazonian freshwater manatee in Brazil and Guyana, but only in captive situations. Heck, I'd gotten right down and hugged them!

I was overwhelmed by seeing free-living wild manatees--so very many--I counted 80 in one turn of my head! Yeah, yeah, I was bawling. I'd waited a long time to see my first wild sirenians, and I'd strained my eyes peering into the muddy waters of many a tropical river trying. This was too easy. It was like they were waiting for a bus, and the bus was us!

While we waited for the fog to clear, we looked beneath the observation dock. Some native Florida gar joined a snook, hanging as if on strings in the water. My GarGuru, FloridaCracker, advises that there may be two species of gar here, so he advised me to go against my Science Chimp instincts and not get too specific. 

The spring was almost choked with tilapia, an African escapee from fish farms. They're cichlids, related to those darlings of freshwater aquaria. Pretty good eating, but it doesn't look like we're going to catch up with their reproductive rate any time soon. Sigh. Fortunately (or unfortunately for Blue Springs), tilapia are confined to waters that stay above 60 degrees year-round, meaning that (so far) only Florida has to deal with them, and, outside of extreme southern Florida, generally around power plant outflows.

Farm-raised tilapia fed on corn may be fattier than bacon or hamburger. (Remember when everyone found out that the fish sandwich at Mickey D's is the worst thing you can order? That was because of the way they fry it, though.) And,

 interestingly enough, commercially farmed tilapia are subjected to testosterone baths as young fry, turning them all into males. In this way, pisciculturists can ensure they raise an even-age batch of harvest-sized fish, rather than having to sort the offspring of their inevitable pairings. These look pretty even-aged to me--where are the juveniles? Dunno.

FloridaCracker says tilapia make huge, meter-wide bowl-shaped nests, crowding out native sunfishes. Bah. Why do so many escaped exotics have to live so darn large?

Tilapia have made it to the International Union for the Conservation of Nature's 100 World's Worst Alien Invasive Species, having been introduced into tropical waters all over the planet.  They're the big boxy gray fish in this photo.

The blackish banjo-shaped catfish are vermiculated sailfin catfish, native to Amazonia and known in the aquarium trade as Plecostomus catfish, or "plecos." One guess where those came from. I'll give you a hint. When I was a kid, I had one in my tiny 5 gallon aquarium along with the mollies and platies, and it got about 8" long so we gave it to the neighbors, who flushed it down their toilet when it got too big for their 20-gallon tank. Never give anything to your neighbors if you care about it.

In an Amazonian fish market in Manaus, Brazil, I saw Plecostomus catfish for sale, stacked like firewood, upside down, their sucker mouths gasping for air. They were about a yard long. I felt bad about that for years until I saw these.

Why do we import things like this, to put in little tanks and then, when they no longer fit in the tanks, to put in our crystal springs, where they dig the sides out and erode them, making their nests? Why do people keep Burmese pythons and then, when they're too big for the  apartment,  turn them loose in the Everglades, to proliferate to terrifying levels? That's just what we do. Dumb stuff like that. Genies get out of bottles and there is no stuffing them back. Especially when the genies like Florida's subtropical climate.

There were other creatures in with the manatees, which caused the big sirenians no concern whatsoever.

This was the youngest gator we saw, still carrying its banded tail.

It was about two feet long.

Even the big gator seemed not to carry a threat to the gentle mammals, who cruised right under it.

Blue Springs State Park is a magical place. Just the original homestead with the new sun beaming through its Tillandsia-draped tree...oh my goodness. We didn't have time for the house tour. Well, anyway, the Science Chimp can rarely be found on historic house tours--she's usually digging around in the leaf litter instead.

We had only one morning, this misty morning burning off to bright sun, before we had to go back to freezing, iron-gray Ohio.

We soaked it up as best we could.  More manatees anon!

The Crane Battle Moves to Kentucky

I cropped off the heads, with their big grins. Hunters tell me it's not hard to get your daily limit with such a huge, slow-flying target. 

We now interrupt our regularly scheduled inspection of armadillo carcasses with this important action alert for wildlife enthusiasts everywhere.  MARCH 15, 2011 is the deadline for public comment on a proposal to hunt sandhill cranes in Kentucky. That's TOMORROW. If you wrote to Tennessee in the campaign this winter, you can cut and paste and change "Tennessee" to "Kentucky." If not, please read my letter, crib bits of it in your own words if you wish, avoiding overly sentimental or confrontational wording,  and politely email Mr. Gassett at this address:    jon.gassett@ky.gov


Copy your letter to FW_Suggestions@ky.gov


Do it now, please, for the cranes. We fought them back in Tennessee; there's a two-year stay on their proposal. We can fight them back in Kentucky, too. The Kentucky Ornithological Society and the Beckham Bird Club have both come out strongly against the hunting season.  Kentucky Dept. of Fish and Wildlife Commissioner Jon Gassett has indicated that if enough people write in protest, the proposed hunting season--due to start this December-- will be reconsidered. Nobody owns these cranes--they're free for all to enjoy. If you think it's wrong to shoot them, please take the time to email Mr. Gassett. THANK YOU!

Dear Mr. Gassett,

I am a writer, naturalist and artist with a special interest in human/bird interactions.

 For my new book, due out in 2012 from Houghton Mifflin Harcourt, I’ve been researching sandhill crane hunting. The sandhill crane has the lowest recruitment rate (average number of young birds joining a population each season) of any bird now hunted in North America. Historic recruitment rates of all migratory sandhill crane populations range from 7.5% to a high of 11%.

 Since 1975, hunting in the Central Flyway has taken around 20,000 cranes annually (E.M. Martin, U.S. FWS report). This represents 6% of the estimated mid-continental spring population of 322,700 birds for the same two decades. Given the projected recruitment rate, harvesting 6% of the population each year in the US alone seems to me to be cutting it too close to the edge. Kills in Canada, Alaska and Mexico are not included in the count. What about all the other birds that die from inexperience, disease, natural predation and accidents? Further, the crane take in Mexico is a free-for-all: neither regulated nor recorded.

 Hunting sandhill cranes in Kentucky is a bad idea from a public relations standpoint, considering the growing cadre of birders and nature enthusiasts for whom cranes are a touchstone species. How can Kentucky possibly garner enough revenue from crane hunting to offset the outrage when birdwatchers find out that the cranes they love and travel to see are being shot? Hunting is on a steady downturn, and nonconsumptive wildlife pursuits are on a tremendous upswing. Nationwide, wildlife watchers now outspend hunters 6 to 1. The explosion in digital photography allows people to stalk wildlife without harming it. Initiating a hunting season on a large, charismatic species like a crane is no way to resuscitate hunting. It is, however, an excellent way to alienate nonconsumptive wildlife enthusiasts, and further polarize the camps.

 Texas and North Dakota together account for 88% of the total yearly kill of sandhill cranes. There is evidence that a unique Canadian prairie population of lesser sandhill cranes is being selectively wiped out, since they migrate over the most heavily hunted areas of Texas. It should go without saying that the incidental kill of endangered whooping cranes is an unacceptable cost of adding another state to the shooting gallery all along both species’ migration route. Of the Central Flyway states, Nebraska alone holds out in protecting the cranes, having proven by its longstanding Festival of the Cranes in Kearney that a crane is worth infinitely more alive and purring in the sky with its family than thudding, broken and bleeding, into a cornfield.  Just ask Bill Taddicken, director of the Lillian Annette Rowe Sanctuary on the Platte River in Kearney. Crane tourism brings that little town around $10 million each year in revenue, without a single shot being fired. 

Proposing a hunting season on a bird with that kind of ecotourism potential simply doesn't make sense. Giving a few hundred hunters something else to shoot, in my opinion, cannot be worth the blowback from tens of thousands of people who are willing to travel and spend just to watch the birds fly over.  Please reconsider this proposal, and consider taking a lesson from what happened in Tennessee. Letters and emails by the thousand poured into the commissioners' offices, protesting its crane hunting proposal. Even more telling, the support the Tennessee Wildlife Resources Commission was expecting from its hunting community simply never materialized. I've received letters and emails from a number of avid hunters who find the concept of shooting cranes repugnant. TWRC's response to the outcry was a two-year stay on the proposed season. I feel certain that, given Tennessee's 18-year track record of celebrating cranes in a tremendously successful festival, the opposition will only be stronger in 2013. I would encourage the the Kentucky Department of Fish and Wildlife to take Tennessee's example as an indication that offering sandhill cranes for hunting will create far more public relations trouble than it's worth. 

Sincerely, 

Julie Zickefoose

Examining an Armadillo

It was a huge treat to find a roadkilled armadillo the same evening, to be able to put my eyes and fingers on this creature and experience even more of it.

That shell is HARD! You can knock on it and it sounds like hard polystyrene. It was more like a turtle shell than the leathery cape  I'd imagined. Of course this specimen was pretty dessicated, but still, the shell was much harder than I thought it would be.

Such elaborate armor for the tail...does the tail have a function? I wonder. It looks like it could telescope out longer, but of course it doesn't. That would be cool, though...

What a marvelous integument this animal has; how specialized is its skin!

What a wonderful world this is.

Armadillos haul lots of dry grass and plant material into their deep burrows, making a cozy nest where they give birth to their four identical quadruplets right about  now (March/April). The young, born mobile and with open eyes, stay with their mom for most of a year, and then disperse. Armadillos can live about seven years in the wild and up to ten in captivity.

I cannot resist lifting some photos from an excellent overview of armadillos on Armadillo online. Because where else are you going to see babeh armadillos? With floppy wet leather, before their shells harden up?

But oh, they harden up fast.

Imagine how fast these razor claws could slice through sand in a rapid descent into the earth, with all four feet churning at once. I've read that they can just disappear in seconds in a big fluff of sand.

Even the top of its head is armored.

Back to the living armadillo: Before long a little crowd gathered, attracted by my crouching form. We all appreciated the armadillo together. I like being in a place where people habitually stop to admire wildlife.

The kids and I were thoroughly amused by the long golden hair on the armadillo's soft underside.

It's an unexpected detail, the mustache on the pretty lady, and it's very cute in real life.  Liam kept saying, "He's so HAIRY!!" I don't know why we expected him to be other thanhairy. Maybe it was the yellowness of it, or the length...it was just a surprise.

Thank you, little armored one, for interrupting your long nap and showing yourself to me and the kids. I owe you one.

Hey! It's a wonderful kind of day! Oh wait. Arthur was an aardvark, wasn't he? 

Our First Armadillo

Warning: This post contains some roadkill photos. Heck, it's a post about armadillos. If it didn't mention roadkill, it wouldn't be about armadillos now, would it? Let's get that first DOA 'dillo out of the way:

There, that wasn't so bad. This poor fella managed to get himself killed in a beach parking lot. That takes some doing on both killer and killee's parts. Armadillos would be OK if they'd crouch down when a car passes over them, but instead they startle and jump straight up, bonking against the chassis and essentially commiting suicide. Armadillos are capable of leaping 4' straight up into the air, so you can imagine the forces when this power is applied to a speeding automobile.

I have always, always wanted to see an armadillo in the wild. Any armadillo (and there are 20 species worldwide, all but one of them in Latin America). In the southern US, we are blessed (or cursed, depending on who you ask) with a single armadillo species, the nine-banded Dasypus novemcinctus.

It's just so cool to have an edentate in the United States. "Edentate" means "toothless," though the nine-banded armadillo is hardly toothless. Here are the weird blade-like teeth of the hapless roadkill I found and examined in Florida. They stood up like an edge cut with pinking shears, more crenulations than teeth. Gross, I know, but look at the teeth, please.

 

Seriously: having an edentate in the US is like our having a flamingo, a spoonbill, an antelope, a lion. It's a lone representative of a cool order we might not otherwise have. D. novemcinctus ranges from Argentina to the southern United States, and it seems to have relatively recently colonized the US, having first been seen here in 1849. Armadillos naturally colonized Florida, but became extinct for unknown reasons. Modern Florida nine-banded armadillos are thought to descend from a pair that escaped from a roadside zoo about 50 years ago in Cocoa, as well as at least one earlier release. Knowing they aren't exactly "native," even if they were historically in Florida, seems to give some people license to hate them. Lots of people hate any animal that digs huge holes, so the cards are definitely stacked against the little armored one. Of all the world's species of armadillos, only the nine-banded has managed to thrive and extend its range. Go novemcinctus!

In deference to Floridians who will doubtless give me their $.02, it's easy to love an animal when it's not excavating your back yard.

But get this: The giant armadillo, Dasypus bellus, once ranged as far north as the Ohio River Valley!! No wonder I was so hot to see an armadillo, even if only its smaller cousin.

Armadillo Online is an amazing compendium of cool armadillo information. Like this: The nine-banded armadillo has a unique salivary bladder surrounded by muscle, a tappable reservoir of gluey saliva that it uses to snare ants, termites, and other insects as it eats.

Did you know that armadillos always have four young, and they are all identical, all the same sex and genetically alike? All four come from the same egg, which divides into four embryos. This makes them good lab animals, because where else are you going to get four genetically identical siblings every time? You've got your experimental animals and your control in one litter. However,  though they quickly become tame, they don't do very well in captivity.

They're also sought after and captured because armadillos can catch and carry leprosy, so a great deal of what we know about transmission of this disease comes from armadillo research. People go out with nets and catch 'dillos and sell them to labs. Unfortunately, people who handle a lot of armadillos sometimes get leprosy from them, yuccch. The armadillo has a weak immune system and an extraordinarily low body temperature -92 to 95 degrees, which is thought to make them susceptible to leprosy. Reason enough not to keep a pet armadillo!

Leprosy, a dreadful lesiony lumpy skin disease caused by the bacteria Mycobacterium leprae and M. lepromatosis, is now treatable with a multi-drug regime of rifampicin, dapsone, and clofazimine given over 12 months. However, the Third World still hosts leper colonies where people suffering from the disease are segregated--over 1,000 colonies exist in India alone. I flew over an island that's given over to people suffering from leprosy in Guyana, in South America. It's still part of the reality for many less affluent countries. That hit me hard, circling over that island just an ocean away from Florida, but decades removed in medical advancement. We are incredibly fortunate in the U.S. I try never to forget that.

Armadillos sleep up to 16 hours a day. Maybe this is why I'd never seen one until this trip to Florida. I've been all over south Texas too, but no go until now. As the kids and I headed to the beach one evening, I saw the trundling shape of my first 'dillo near a busy intersection. I whooped with joy and pulled over to document it.

Absolutely beautiful it was, a perfect specimen.

I was impressed by its muley ears and perfect carapace; its birdlike snoot and tiny eyes. It spent 90 per cent of its time with its nose deep in the grass, looking for insects to eat, so I have dozens of photos but only a few where you can see its little eye. This is one of them.

More armadillo exploration anon.

Fun on Biolab Road

A young roseate spoonbill greeted us as we turned onto Biolab Road.  What an alluring name for a road!

                                This is what a black vulture does when it's really, really windy.

I like how he's using his tail as a brake, and he's clinging for all he's worth to the snag. Vulture feet are not strong in the clutching department, which is why they have to carry prey in their beaks.

Black vultures are a Florida fixture, and they call southwest Ohio their year-round home, but they're still pretty unusual to see in southeast Ohio, where we live. I have a feeling it's only a matter of time before they completely colonize my area. We have roadkill aplenty. You could live on roadkill around here, if you wanted to. Which I do not.

Bill had told me that Biolab Road was a must-see, and we were not disappointed. Phoebe said it led to the beach, and that seemed like a meet adventure for a mom and two cubs...drive down the road and wind up on Cape Canaveral's beach. We drove and drove, rolling slowly along, taking in the incredible wildlife along the way.

The kids loved the reddish egret, especially when I told them that birders call it the "drunken clown" for the way it staggers about in the shallows, following the lightning-fast movement of schools of fish which only it can see.

It throws out its wings for balance, making a spectacle of itself. To someone who doesn't know that it's fishing, it looks crazy, possessed, drunk.

And then it plunges its rapier bill straight down into the water to stab at little fishies.

 A far more placid feeding style distinguishes the roseate spoonbill. I felt incredibly lucky to be able to show this bird to my babies.

The spoonbills are more filter feeders, running that great appendage through the silt and snapping closed on whatever lives within.

They swing their great heads side to side, slowly sweeping through the shallows. 

They make pass after pass in an unconsciously lovely ballet.

Earlier in the day, we'd lucked upon a preening group of spoonbills along Black Point Wildlife Drive in Merritt Island NWR.  I quickly deployed the Leica scope and camera to digiscope their sickly green heads, ruby eyes and glorious crimson shoulders.

Could there be a much more convincing link between the dinosaurs and today's birds?

It was not much of a stretch to imagine duck-billed dinosaurs snapping to attention at the approach of a pack of Deinonychus, especially for Liam.

So long did we watch and admire the wading birds and snoozing gators that it finally became clear that we would never reach the beach before dark

and we decided that that was fine with us, because what could be better than this pastel sunset, with us all breathing the salt air, appreciating the heartbreakingly beautiful color. Color has been gone from our lives for months and months. We decided that all our color had drained down into Florida. We're very anxious to get it back, as rainy day follows rainy day and the crocuses struggle to bloom.

Phoebe snapped me in pursuit of egrets

and I snapped her in pursuit of sunsets

and it was all dreamily beautiful. We hated to see that sun sink, but it was kind enough to go behind some cutout palm trees, delighting Liam who thought it was time for the pterodactyl to swoop through, cackling, at any moment.

A snowy egret punched a white hole in the inky marsh as we said goodbye to another Florida day.
