    SALT AND FRESHWATER LAKES

Larnaca saltlake birds

Saltlake. first rains. arrival flamingoes. image Whenever the first rains occur greater flamingoes land on the salt lake. The rains bring the brine shrimp larvae to the surface and the flamingos like to eat the shrimp larvae. They also feel safer surrounded by water. The brine shrimp lays fertlised eggs in the sand which will hatch only when conditions are right, that is when lake is full of water, and the salinity of the water does not exceed 25%. Flamingoes arrive at the earliest in November, depending on rainfall, and leave at the latest in June. when they fly north east to breeding grounds in Turkey. (watch video)

Saltlake. flamingo feeding. imageFlamingoes are filters feeders. They prefer to feed in water 5 to 50 cms in depth but will also feed in much deeper water. Stationary, with their head submerged upside down in the water, their bill pointing backwards, they tread in one spot turning in a circle, disturbing the mud with their feet, and suck the water into their bill. The delicate keratine gills in their mouth grasp and swallow the solids, then squeezing out the water from the sides of their bill. When upright the cup of the flamingoe's beak is on the top, which only makes sense when feeding as the head and the beak are upside down the cup is now on the bottom holding the food before swallowing. Their food is brine shrimp, larvae of chironomids, small molluscs, crustaceans and plant seeds. They will eat 200 grammes (7oz) a day, 60 grammes (2oz) dry weight, per day filtering 20 litres of water in the process. As there is no competition for brine shrimp from other birds, the flamingos can stay on the lake in large numbers. They arrive when the density of algae and brine shrimp are at their maximum and stay until the supply is depleted to one quarter of its original density, when they will move on. The minimum concentration of algae in the water is 3 grammes dry weight per litre before the flamingos will have to move on. The shrimp recover very quickly, returning to normal levels in under two weeks. This emphasises the unique value of several saltlakes within flying distance, as exists in Cyprus, for the birds to fly between and to return to lakes following the variation in availability of food. There is also an need to manage all the Cyprus lakes to provide a home for the flamingoes. Their food contains carontenoids made up of carbon, hydrogen and oxygen sythethised by the algae, that converts to pigments in the flamingoe's body, that form the canthaxanthin in their feathers. This turns the flamingoes pink.(watch video)

Saltlake.flamingo behaviour. image Flamingos have a array of distinctive body movements which are thought to indicate to prospective mates that individuals fitness. The more vigerous the movements the fitter the bird. These displays are more frequent as the flocks are preparing to leave their wintering lakes and set off for their breeding sites. Marching A group of birds, standing upright, one bird almost touching the bird in front, set of on a fast walk, head flagging as they move. Head flagging. One bird will lift its head into am alert position, with its bill pointing upwards, and start to turn its head from side to side. once one bird has taken this posture others follow. Wing salute. Usually following head flagging. Each bird, with its head held up and its kneck outstretched, spreads its back feathers, cocks its tail into the air and flicks its wings open. It will hold this position for a few seconds and then snap its wings shut. Inverted wing salute/Bowing The flamingo lowers its kneck, cocks its tail into the air and partly opens its wings over its back with the tips pointing upwards.This lasts just a couple of seconds before the wings close again. This movement is more often made by the females. Twist-preen. The head flag and wing salute is usually followed by a twist preen.One wing is held above its back while the bird twists its head and kneck around as if it is preening. Wing stretch. The flamingo stretches one wing and one leg on the same side of its body to the back. Hooking. An aggressive action against other encroaching flamingoes. The head is held forward horizontally with its beak pointing back into its chest. Kneck swaying. Another agressive gesture. The flamingo sways its head and kneck to and fro.(watch video)

 

Saltlake.flamingo moult. imageFlamingos moults are irregular but usually occur once or twice a year depending on the age of the bird and takes place over winter to early spring. The discarded feathers wash up along the shoreline providing ideal material for the swallows to line their nests. If the flamingos loose and replace their flight feathers gradually over the winter then they will still be able to fly, but if the moult happens over a short time then they will be flightless and vulnerable. Flocks tend to synchronise their moults, as the group can better protect itself rather than allowing flightless individuals to manage by themselves.(watch video)

 

Saltlake.flamingo sleeping. imageFlamingos sleep with both legs tucked under their bodies, or standing on a single leg, head held in front of their body or curled into an "s" shape along their backs. For protection they gather into tight flocks with the individuals at either end keeping an eye open. (watch video)

 

Saltlake.flamingo short flights.image Flamingoes fly around the saltlakes, always looking for the most abundant supply of their food. And as time for their departure grows nearer flights become more frequent as wings and communication is tested, They take three or four running steps to propel themselves into the air and three or four running steps to steady themselves as they land. By March these flights are more frequent as the food in the lakes is becoming depleted and more movement is needed to find the best spots. Finally as the water recedes and food becomes scarcer, one after the other, the flamingo flocks take off for good, heading east for their breeding colonies in Turkey, Afghanistan and Iran.(watch video)

Saltlake. flamingo predation. imageAdult flamingoes are over six feet tall and quick to take flight. There are not many predators who would be able to bring them down. But pollution in the water, the outflow from drains of neighbouring houses, and overkeen child hunters with their first air rifle, will. All the saltlakes, except Paralimni, are protected and this sort of activity is prohibited. But occasionally it still happens. (watch video)

 

Saltlake. flamingo young. image Young flamingoes are the last to arrive on their wintering grounds and the last to leave. They will not mate until they are 5 to 8 years old and so do not share the same pressures as the adults to establish a nesting site on their summer breeding ground. As they are raised in creches they are used to sticking together and migrate to and from their wintering ground in flocks of young birds, guided by a few adults, and remain in these flocks throughout their winter stay. Their plumage is black and white. They will be two years old before they will grow pink flight feathers as they will have not yet consumed enough of the carotenoid to produce the pink colouration. (watch video)

Saltlake.flamingoes depart. image The saltlakes dry out completely over summer and cannot provide the protection anf food needed by breeding birds.So the flamingoes will leave. The frst signs are a creschendo of hoots as they seem to alert one another, opening and closing their wings as if in practice flight, dipping their heads with their wings pushed upwards, raising their heads up and down, moving their heads from side to side, and walking purposefully in circles. Then they take off in huge groups. Individuals some way away will join in and, once in the air, smaller groups split off from the main group and circle back as if to pick up straglers. Then they head off east, either following the coast or the line of the Trodos mountains, before turnng north, to join flamingoes migrating from Spain, Italy, Iran, Israel and India on the breeding grounds on Lake Van and the Gadiz delta in eastern Turkey. Other breeding lakes in Turkey, Akgol and Burdur have dried up due to drilling and climate change. Young birds, with black wing feathers, without the pink of the mature birds, stick together in juvenile flocks, and are the last to leave, with no urgency to establish a breeding territory. Flamingoes will start to leave from Febuary although it will be late June before the last birds have left. In winters of heavy rainfall birds may be on the lakes even later as long as there is sufficient water to feed and keep safe from predators.(watch video)

 

Saltlake. small birds. imageSome birds like the hooded crows, owls and kestrels, live around the saltlake for the whole year. Most of the smaller birds are staying for just the winter before moving on to breed further north. During their stay they need be aware of predators, the most deadly being the kestrel. Crows will see off a kestrel by acting together, mobbing him, and forcing him out of their territory.(watch video)

 

Saltlake.autumn migration.image The saltlake is a safe resting place for migrants. In autumn, with most of the water evaporated, there is no food for the birds. They have landed here simply to rest. With wide visas, it is easy to spot predators before they can cause any harm. Flocks of grey heron and demoiselle cranes sit at the centre of the saltlake within sight of the mosque, while glossy ibis, egrets and waders black backed stilt and spur winged plover prefer the reedbeds near the aquaduct at the northern end of the lake. They stay for just a few days.(watch video)

Larnaca saltlake foxes

Saltlake.fox cubs. image There is more than one set of breeding foxes around the saltlake, each producing an average of two cubs. Normally the parents will bring back carion to the set to feed the cubs, but these two cubs are orphans. They have found foster parents who have stood in to provide food until the two become independent. But they are very wary and approach very slowly. Their distrust of humans will hopefully keep them alive. (watch video)

 

Saltlake.fox eats. image Foxes live and breed in the wild copses that surround the saltlake. They establish a territory which will have a safe den underground to give birth to their cubs and access to food. The bushes around the saltlake harbour birds lizards and rats, all food for foxes. Foxes hunt but they are also scavengers and are as adept as feral cats in finding leftovers in dustbins. Once a territory has been tested and found safe, then families of foxes will breed in the same territory from one generation to the next. They are shy animals, seldom emerging before dusk, and very wary of humans. With good cause. As now hunting pressure groups are trying to reinstate the fox as a legitimate target for their guns. (watch video)

 

Saltlake.cat and fox. image Cats and foxes are both hunters and scavengers and their paths cross often as they seek out the same food scources. Nomally a cat will give way to a fox. But as the outcome is uncertain if there should be a confrontation, fights are avoided. There are feeding tables around the lake where people who care for the wild animals will put out scraps. The cats will often be waiting safe in a tree and,less wary of humans, will be the first to feed. The fox approaches later when quiet has returned. (watch video)

 

Saltlake.beagle and fox. image Beagles are the traditional hunters of foxes. But this beagle, abandoned on the saltlake, has found it better to co operate rather than compete, at least at mealtime. He knows when food is put down for the foxes and he has come to share. The fox and the beagle dance around each other a little but settle down to each take a mouthfull. (watch video)

 

 

Saltlake.fox family eating. image When food is readily available foxes will share with close relatives. Four foxes share a meal of dinner scraps put down by a walker. This meal point is regularly replenished and the foxes have come to know this and that there will be enough food for all. The dominant fox, with face marks resembling black eye tears, eats first while a smaller fox with similar markings watches and eats when the opportunity arises. Two other foxes watch and pace in the background afraid to approach before the larger fox has finished. A lighter coloured fox, with less distinct eye markings, approaches first. When he leaves, a fourth fox with black socks on his/her front paws, warily approaches to mop up what little is left and quickly retreats. This group remained together for a month, before they were disturbed by moving heavy machinery near the earth, after which the group split up and dispursed. (watch video)

Larnaca saltlake trees and flowers

Larnaca saltlake.eucalyptus forest.imageThe eucalyptus is a tree with a flaking bark, shallow widespreading rootes, and long pendulant leaves growing in clusters, white, cream, yellow, pink or red flowers, woody cone shaped fruits with valves that open to release its seeds.  Its leaves produce the eucalyptus oil that is used as a perfume and disinfectant. The petal structure of the leaves let the light  filter down to the ground not shading out the shrubs that grow beneath the tree. Eucalyptus trees were introduced by the British late 19th century.  In 1879 a forester A.E. Wilde,  seconded from the bBitish consulate in India, planted the first Eucualyptus seeds. Eucalyptus spread  out their rootes  sideways under the ground and will draw up water from a wide area around the tree. Cyprus at that time was hit by frequent malaria epidemics, one third of the population of Nicosia died from the disease in one year 1986. Today older people remember as children, loosing brothers and sisters to the disease.The mosquito larvae breeds in shallow pools and it was hoped that the eucalyptus with its unusual roote pattern would drain the saltlake swamp  destroying the mosquitoes breeding sites. The last case of malaria was recorded in Cyprus in 1967, the same year the WHO declared Cyprus malaria free. A Turkish Cypriot, Dr Mehmed Aziz, health inspector for the British government in the early 1900s was responsible more than anyone else, for the eradication of malaria in Cyprus. The eucalyptus also played its part. Today there is concern that the Eucalptus draws up water that might be better used for irrigation, but its unusual roote pattern does not penetrate the deep aquafers where the water flows and so the tree does not divert water from crops or town water supplies. It does not compete with native shrubs in the mountain forests and so does not endanger native Cyprus trees.  ( An article by Serkan Ilseven and Mert Basson our pdf page explains this in more detail) The eucalyptus is native to Australia, part of the myrtle family, of which there are over 700 species. 16 species can be found in Cyprus of which two, the blue gum eucalyptus ( eucalyptus globulus) and the red gum ( eucalyptus tereticornis) are most often found. The eucalyptus adds a layer of bark each year as the old bark dries up and peels off the tree. The gum resin from the bark is used as a colour die for silk and wool giving a natural green to red hue. The leaves contain an oil which serves as a powerful disinfectant and insect repellent, and a sweet perfume. The tree itself regenerates quickly when cut down and so provides a replenishable scource for pulpwood and paper production. It is favoured habitat for bees as it is the only tree in flower from October to December and so loved by beekeepers. So in all eucalyptus is a productive tree for humans. On the saltlake the forest is a hunting ground for the kestrel and tawny owls, shelter for the hooded crows, and migrating beeeaters. Foxes build their homes in the undergrowth. Mimosa and buckthorn are the most common shrubs growing beneath the trees providing nectar for bees and  berries nutrition for small birds. The shallow rootes of the eucallyptus make it vulnerable to high rainfall and strong winds. In  the spring of 2020 a large magnificent tree crashed to the ground. Young eucalyptus will sprout from seeds which had laid dormant in the ground as full sunlight penetrates for the first time and the fallen tree will likely regrow from its stump. (watch video)

Saltlake.spring flowers. image The rains are followed by a greening of the banks of the saltlake. Asphodel is the first flower to bloom, with anenomes and crocuses suceeded by the barbary nut iris, yellow trefoil, blue scarlet pimperel and asparagus pea, Many of the flowers, like the iris and anenome, grow up from bulbs in the ground in the same places every year. They spread by sending out rhizomes under the soil, extending their colony very gradually over time. As they don't rely on insects for reproduction they can flower earlier than other plants. Rarer plants like the naked man's orchid also propagate through rhizomes, and so also appear in clusters in early spring, but they need a special fungus to thrive and so remain rarer and localised. Other early flowers, like the rest harrow, pimpernel, cape sorrel, grass vetchling, wild garlic and crown daisy are insect pollinated and so flower later, their seeds carried over the entire bank of the saltlake. (watch video)

 

Larnaca saltlake.early summerimage .The banks of the saltlake change from green, interspersed with colourful spring flowers, to uniform brown as temperatures rise and rainfall decreases. The most visible plant of early summer is mimosa with its dense display of yellow flowers. The mimosa, like the eucalyptus, the dominant tree on the saltlake, is an import from Australia. Migrant birdslike the reed warbler, are on their way from East Africa, to breeding grounds in central and northern Europe. A few remain to bred in Cyprus.The beeater flies from western and southern Africa to breed in southern and eastern Europe. Small numbers have bred in Cyprus. Beeeaters burrow a hole into sandy banks to lay their eggs, breeding in dense colonies. Although the colourful early spring flowers have died away, there is a subtle variation in colour amoung the grases, from green through brown to red.The lake is filled to the banks, even as late as May and June, but a carpet of algae floats on the surface, created by the increased oxyen levels resulting from the recent inflow of grey water from nearby houses. (watch video)

 

Saltlake.late summer flowering plantsimage .With its yellow petals and red stamen, the flowering Jerusalem Thorn is quite striking. It is one of the last flowering plants before the summer heat withers any delicate vegetation. The bumble bees and wasps drink it's nectar, taking pollen from flower to flower at the same time, propagating the plant. Only specialist salt tolerant plants can grow in the conditions on the banks of the saltlake, plants like the saltwort and glasswort. These plants can grow here as they have mechanisms for dealing with the salt which is drawn in the water the plant needs to survive. Some of the salt is pumped back into the soil through the plant's rootes. What salt is taken up into the plant is absorbed and stored within its cells. When the concentration of salt becomes too great in some stems, they wither to be replaced by a younger growth and the cycle is repeated. Late in its annual cycle the glasswort turns brilliant red. Subsequently some stems die away to shed excess salt. (watch video)

 

Saltlake.agave plants in flower. image A native plant of Mexico and related to the yucca. The agave flowers only once, every ten years or so. It sends up a stem to a height of thirty feet, to bear its tubular flowers which turn to seed over the summer. Once the seeds are dispersed the parent plant dies. In the Meditteranean the american agave is the most common, known as the century plant as it takes so long to mature flower and produce seeds. Young plants can also grow from the roote system.The argave is a natural sweetener and a food scource. One variety is the main ingredient in the production of tequilla.(watch video)

 

Larnaca saltlake.Limnatis.fallen trees. imageOnce weakened, sucessive years of drought will kill a tree altogether, or so weaken it that a strong wind will bring it down. Once it has fallen, fungi and insects get to work, absorbing the bulk of the tree little by little, returning its nutrients back into the soil. The bracket fungi and crust fungi creeps over the surface of the tree while the weevil and the chafer beetle burrow into its centre. Beetles and ants both eat into the dead tree and lay their eggs in the caveties, accelerating the trees decompostion as their offspring do the same. Bit by bit the dead tree breaks into smaller pieces until it disintergrates altogether. (watch video)

 

Larnaca saltlake walks

Larnaca saltlake.walk at dusk. image A walk around the saltlake at dusk reveals the shy animals that hide away during the daylight. On the receding waterline, noisy black winged stilts pick insects off the lake surface and crustaceans like the brine shrimp from the water. They arrive in June, depending on how much sand has been exposed by the receding water, and leave together, over just a few days, in early August, possibly to other local sites where the feeding is better. Swallows give way to bats, the nightshift, both sweeping for insects. Crows roost as the owls wake. Two types of owl hunt on the borders of the lake, often in pairs, the scops owl, distinguishable by its erect ear tufts, and the smaller little owl. They swoop over bushes picking off insects, mice and frogs. The largest mammal of the saltlake, the fox, is also a hunter. The vixen brings back food to her cubs, sometimes a crow, sometime even a feral cat. If he doesn't eat it, the cub marks it as his for eating later. The Cyprus fox is protected as it is a unique Cyprus species. Also brought out by the night are are the smaller mammals, the hedgehog and the field mouse. (watch video)

 

Larnaca saltlake.spring floral walk. image After a late but long period of rainfall the grasses of the saltlake break out into colour with a succession of wildflowers. On disturbed ground light and water trigger seeds into growth. Poppy seeds can lie dormant in the soil almost indefinitely, before exposure to light will stimulate growth. These opportunistic plants of disturbed ground, corn poppies and crown daisies, are annuals, which, once pollinated, will wither away, leaving their seeds in the ground for the cycle to repeat.They grow in different places each year, wherever their seeds fall. At this time of the ear flamingoes are on the lake in large numbers.Some will stay till late Spring but most will move before the last of the rains. They fly east, setting off on their migration to their breeding sites in Turkey. They follow two rootes over Cyprus, either following the south coast or the line of the Trodos mountains. Amoung the grasses perrenial plants like the thistles, grow in the same place every year. Their roote system buried in the soil, is stirred into growth by the Winter rains, push up their stems, flower and then wither, with their rootes always secure under the soil. Other birds visible on the lake in numbers are the swalows and swifts. They fly in flocks over the grasses and and over the water sweeping up the myriad insects that hatch in Spring. Some perrenials have developed an extraordinary relationship with other plants that provide nutrients they cannot generate for themselves. Broomrape, looking a little like an anaemic orchid, cannot produce chloryphyl and, on the saltlake, relies on pine trees to provide it. They grow under the pine, formng a perfect cicle under its canopy, extracting clorophyl from its rootes. The most exotic plants include the orchids and broomrape. These plants grow in small single colonies and can be found in only one or two spots around the saltlake. As the water of the lake starts to evaporate, wading birds, like the blackbacked stilt fly in to feed from the insects exposed on themud and in the shallow water. Most of the flamingoes have left. Often it is just the juvenile flamingoes that remain behind. As they do not need to compete for nesting sites there is no rush to leave, as long as water remains on the lake. Now the last of the flowering plants are showing, the wild leek and blue cardodatium, as the grasses yellow and wilt in the increasing heat. (watch video)

 

Larnaca saltlake.summer floral walk. image During the long scorching six months of summer, from May to October, plants wither and colour evaporates from the saltlake. Groundhugging plants with very small flowers like the heliotrope manage to keep their flowers into early summer. The caper flowers after dusk when the daytime heat has diminished. From June even the grasses dry out. The thistle husks are the only reminder of the springtime blossom. Red and green dragonflies hover over the vegetation, engaging in courtship races, returning to a familiar stalk of grass, waiting for a mate. A dragonfly lives for a single year, of which only two months in late summer are spent in its adult form when it is seen flying between plants. The rest of its life is spent as a nymph under water. In its two months as an adult a dragonfly finds a mate and lay its eggs under the surface of the saltlake for the cycle to repeat, eggs hatching into midges, which undergo several moults before finally emerging as adults next summer. If not first plucked from the water by overwintering flamingoes. (watch video)

freshwater lakes and ponds

Achna reservoir.autumn migration.image Birds have a high metabolism and so need to eat constantly. When food becomes scarce they will migrate to new places where food is more abundant, they relocate to a territory that is optimum for them. Migration will consume up to 40 percent of the birds bodyweight, so the rewards in energy conservation when they reach their destination must outweigh this loss. Not all birds migrate. Common feeders with a generalised diet will usually stay put, while birds with more specialised diets will fly south in persuit of their favourite food. As lakes freeze in the north water birds fly south to find open water. Herons, egrets and bittern are fish eaters and so look for open water with a supply of fish. The reservoirs fit the bill exactly. These large birds use thermals, upward drafts of air, to aid their flight and as these thermals are only found over land, normally these birds will avoid flight over the sea, rather following the mainland coastline. The birds on the Achna reservoir have followed southerly winds which have brought them to Cyprus.If there is enough fish, some will overwinter here, but most will fly on to the Middle East, and Africa, north of the Sahara. (watch video)

 

Oroklini marshes.waders. image Waders arrive later in the spring, when the water levels on the saltlake have receded. As they feed from the waters edge as they cannot reach their food when the lake is full. Some waders, like the black winged stilt, the ruff and plovers tolerate the salty conditions on the lake, while others, like the snipe and sandpipers, prefer the clearer water on the Oroklini marshes east of Larnaca. (watch video)

 

Spiros reservoir. freshwater birds. image One pond on the saltlake has been dug and lined to take recycled water from Larnaca. This is greywater pumped on to be used by agriculture. It is fresh not saltwater, and the lake is much deeper than the saltlake and stocked with fish. This attracts freswater birds who like to eat fish, and diving birds who feed from molluscs on the reedbeds on the bottom. Cormorants, buik swans, grebes, and even pelicans visit this pond.
