It was another humid Florida Keys day, with record setting heat, when a naturalist friend alerted me to a very rare bird sighting. The tip came from a true photo enthusiast, who sadly possessed only an iPhone. I gathered up my professional photo gear and showed up in the hopes of getting a shot. OK… Though most of my photo archive consists of photos of birds flying away, I am optimistic. The first rule of photography… always have your camera ready so you can be there to get the shot. The thing about the iPhone is you will definitely have it when something happens, and though they are amazing, they fall short on details. The rare birds were a pair of Black Swan (Cygnus atratus) which had been parading back-and-forth in a small cove on the Atlantic side of North Key Largo. The second rule in photography, is you have to be lucky; I was pleased when the swans decided to come to the shore and greet me. My friend called me a “swan magnet.” These birds possessed no fear at all. Was it the bold blue hydrangea print dress I was wearing, or maybe I represented a source of food, as people tend to befriend wildlife in nature. I lingered for the best part of an hour, took dozens of swan portraits, before they retreated offshore as the tide was going down, and more feeding grounds opened up on the flats. It was a breathtaking scene, with Carysfort Lighthouse on the distant horizon, sport fishing yachts and sailboats passing by, and even some paddle-boarders moving through. From time to time I would see a flash of white feathers, as they dunked and bobbed, but wasn’t sure where on their body, as they were so far away. Ecstatic that I had been able to witness such a beautiful display of nature, I headed home, eager to share my discovery with my husband, whose first reaction was, “oh that’s very bad.” Huh? I was more thinking this was a gift, and I was blessed to witness it. As a child, I recall seeing White Mute swans paddling in the canal behind our home off East Las Olas in Ft. Lauderdale. We’d feed them scraps of bread and enjoy their presence, but one day these graceful creatures, whose only predators are birds of prey, mysteriously disappeared, amidst rumors of foul play. Maybe that’s what my husband was thinking about… that humans can be so cruel sometimes? I later returned to the cove, and they were still there, but a Great Blue heron had now befriended them, and they were happily feeding side-by-side. I thought for a moment, how is the Blue heron reacting to these strangers? Has it ever seen a Black swan, with a long neck such as this? All of a sudden one of the swans fluttered up and revealed a beautiful white underside to an otherwise black feathered body. I captured many images of these swans, both close-up, and far away… so much for my theory about birds flying away! I logged a few photographs on iNaturalist (www.iNaturalist.org) to confirm the identity and search for places where Black swans had been observed; the closest to the Keys was Fort Lauderdale, but very few overall had been reported. There are estimated 500,000 Black swans in the entire world. The Black swan is a non-native species, and there are no breeding populations in this area, They are migratory, and their origin is southeast and southwest regions of Australia. Florida is home to three species of swan: the Mute swan, the Trumpeter swan and Whooper swans. Factors that may have attracted the Black swans to this area include the search for more abundant food options, and migration patterns. They are typically found near lakes and ponds, with fresh water and cover needed to survive, but they frequent brackish environments during migration times when resources become scarce elsewhere. 80% of a swans diet consists of plant based food sources, but they will also eat small fish, mollusks, insects, crustaceans and worms when available. While online, I checked my email, and my husband had sent me info about the “black swan theory”, often used as a metaphor for an unexpected event, that plays a dominant role in history. Up until a Dutch explorer in 1697 discovered Black swans in Australia, people thought that only white swans existed. In the financial world, a black swan event is seen as an event that negatively impacts the stock market, catching investors off guard. Recent examples include the dot.com stock market crash, and the housing crisis that caused recession. Hope that as I stand in proximity of a ga-zillion dollars worth of real estate, their rare visit is not a forewarning of some future event.

My favorite times of day are near dusk and dawn. The time of day, when the shadows get longer and you can sit outside without a hat on, with coffee or cold drink in hand, and contemplate the wonders of nature. It’s the time of day full of chirping and songs, and the emergence of the critters. It’s the time before the sounds of daily human activities; the din of lawn mowers and leaf blowers, the constant chatter of workmen nearby. Think of how your morning walk would change if you pulled out the headphone plugs, and simply listened to the sounds of nature. Tune in not out. I will use my iPhone on nature walks; it has an app called “Merlin” that listens to and records bird sounds, and in real time suggests a possible identification. For me, a nature lover who basically knows nothing, it has opened up a world of knowledge, and has brought me even closer to nature. As the names of birds are popping up on the screen, you get an idea of what may be making the sound, and aiding you in visually identifying it. The app can also be used by someone with a hearing loss, someone who can hear, but the sounds may not be crisp enough. As areas are developed, and natural land is changed, birds lose their favorite trees and water sources. Several of my friends have installed screech owl nesting boxes, in their yards, within view of their windows or porches. In the wild, screech owls nest in abandoned holes created by woodpeckers for example. Before I get a nesting box, I need to use “Merlin” to see if I already have owls in my yard, or vicinity. There might just be a natural "house" in my wooded acreage. “Birders” are a pretty great bunch of people. A friend was invited for a cocktail at the home of a neighbor who had a “screech owl” nesting box in a palm tree outside the porch. Yes, lively Key Largo nightlife…sipping on a drink while listing to the “HOO”. She later found an appropriate spot in her own yard, where she could enjoy the owls, who came year after year thereafter, until hurricane Irma tore the house down. Have you ever heard someone say they never see any birds in their yards? Or maybe they do not know where to start looking for birds. The answer is, look in your backyard. Ask yourself, what does a migrating bird or even a local bird, have to eat in your yard? Do you have any native plants? With development and habitat loss, there are increasing pressures on wildlife. If everybody just planted one native plant, that's a start. In a suburban jungle one native tree may be fruiting, while in another there is pollen and nectar attracting bugs and caterpillars. That is what they need to eat. It's like you going to the store and there is only cat food there. What are you going to eat? Birds need fresh water, and cover too, so they may hide from predators. Owls can be a great source for natural pest control and it is free. No pesticide service or poison filled plastic boxes needed! Screech owls feed on all sorts of bugs, cockroaches, lizards, beetles, moths and rodents. Whatever they can see, catch in the air or pounce on is fair game. Spraying for bugs eliminates a food source. Owls can also be threatened by pest control of the another kind… rat traps containing poison are a huge problem. The rat entering the box does not just eat the poison and die there, they eat the poison, then leave the trap, to slowly die from the effects wherever they wander off to. Unfortunately for the birds of prey such as the owl, or the hawk, that same poison does not discriminate between the rat, and the bird that just ate the rat. For all of us, birds alert us to seasonal shifts like migration, teach us about communication, and the cycle of life through behaviors like predation, mating and nesting. Screech owls mate in late fall, and you can hear their noises. The baby owlets emerge from the nesting boxes in April or early May. Nature is the Law. It makes me want to get up early in the morning and keep going. The ecosystem is provided free of charge, no accessories required. And the benefits are lower rates of anxiety, depression and stress.
Anyone out there ready to turn back the hands of time to the way things were in our youth? Our house pets were dogs and cats; they taught us responsibility, and were family members. There were also goldfish, a small turtle lagoon, caged parakeets or hamsters, and fluffy white “Blossom B Rabbit” who lived in a pen under the shade tree. Exotic creatures lived in zoos; venomous snakes, alligators and crocodiles were housed at the Miami Serpentarium until the late 70’s. . Soon people began buying a new kind of pet: the harmless looking baby snake, sitting on a rock under a heat lamp in a pet store terrarium without thinking that when mature, the creature would be 20 feet long, weigh 200 pounds, live more than 25 years, and must be fed with live mice, rats, and eventually rabbits. There were reports of pythons in the Everglades in the ’70’s and 80’s, most likely caused by people releasing their unwanted pets, to happily slither off into saw-grass marsh or cypress slough. Look out for snakes in the proverbial grass! If it were only that easy. For years Everglades park managers were convinced these invasive snakes were escapees, or former pets, not part of a breeding population. Florida offers virgin hunting grounds for pythons, who are carnivorous, but aren’t picky. Last year in N. Key Largo 40 pythons were captured. These captures were humanely euthanized, and then necropsied to examine their stomach contents, which revealed a diet of possums, raccoons, woodrats, and cotton mice. Pythons are biological vacuum cleaners, their jaws are fitted with sharp, inward-curving teeth to grab their prey, while they coil their body around it. Pythons are ambush predators, so they patiently wait for animals to go by for their next meal. The number of possums and raccoons in our area is fairly high; this may be because the Keys are fairly early in the python invasion, and/or because there are a lot of food resources available, so more young are born, and survive, Poor Henry the Westie, family member of Julie and Rob, who one day on his regular “potty break” was traumatized by a near fatal encounter with a large python lurking in his backyard. It was the quick thinking of his dad, who snatched him from within inches of the pythons head. Later on Julie got to wondering where had the raccoon gone that regularly visited her pool for a drink. She concluded it must have been nabbed by the python. She said there was a feeding station next door, and that may be why the python has chosen this area to hunt. Soon after hearing this, I began scanning my property for potential food sources that may attract pythons, and guarding my doors from my cat’s possible escape. The snakes have migrated to the Keys over land and by water, and are adapted to hiding underground, in the cracks and crevices of a geological ancient coral reef. There is whole subterranean world under our feet; a space where pythons have the ability to occupy and where man has an inability to detect, and they stay beyond reach in impenetrable mangrove swamps. So how many pythons are there? Too many! Some distrust the agencies putting out the data, and believe the numbers are exaggerated for whatever reason. I'm no scientist, but the fact is pythons never were in my neighborhood before and now they are. EDDMAPS is a website, that shows on a map, the actual places where pythons have been sighted or captured. The best thing people can do is be on the lookout for pythons. The most important thing to do if you see a python is take a photo. Document it, and then report it immediately. Percy the python sniffing dog is successful if it is a very recent sighting, a few hours or a day, but not more than that. If you see a python, call 1-888-IVEGOT1 As homeowners we should adopt cultural controls: things we can do to modify the habitat, without physically or chemically harming animals. We can eliminate food sources that attract small mammals such as rats, possums and raccoons to our homes. To prevent infestation of not only rats, but also pythons. we can close up crawl spaces under our homes, place mesh over vents that may be missing or cracked, and eliminate any holes big enough for critters and snakes to go through.
Indeed, things have changed since our youth. The night watchmen and security patrols have always had an eye out for suspicious human activity while on patrol; now their watch must be expanded to include the night creatures, If you were to drive on CR905 at night, you would potentially see pythons cruising the side of the road. Agencies must make it a condition of employment, and provide the training and incentive, to remove the python, not just drive right by it. |
