It's simple - Lake Kerkini offers some of the most accessible, and best, opportunities for both birding and bird photography in Europe. As the year unfolds January and February can be cold, and, wildfowl numbers reach their peak with over 20 000 Pochard often with a handful of Red-cresteds. Spotted and White-tailed Eagles are frequently seen, Great White Egrets are everywhere. Dalmatian Pelicans are looking their very best and Cranes are increasingly arriving to spend the winter here, with 28 in February '13.
Migration begins in early March, with the arrival of pioneering Garganey and Osprey. White Storks arrive towards the end of the month. Migration gathers steam through April into early May, when every bush seems to hold warblers. Glossy Ibis are regular and there can be over a thousand of each species of pelican.
The early summer sees the drowned forest alive with herons and egrets. Golden Orioles sing in the poplars and Bee-eaters and Rollers sit on the wires. Great Spotted Cuckoo bred in 2010.
Returning wader migration begins as early as late June, continuing into October, although by then numbers are small. The autumn sees the water level at its lowest, exposing acres of mud, particularly at Mandraki and along the eastern embankment. This is attractive to waders but they are often some considerable distance away. Collared Pratincole pass through in good numbers in early autumn. Pelican numbers build again as Dalmatians arrive to spend the winter and Whites stop off on passage.
October typically sees the Lesser-spotted Eagles replaced by Spotteds. The remaining months bring the ducks back, together with Lesser White-fronted Geese, which spend time here before moving on south-east to the Evros delta.
In the winter of 2007 - 2008 the total number of birds on the lake was counted at just over 41000.
There is also great birding to be had in the nearby hills, with Long-legged Buzzard, Rock Nuthatch, Calandra Lark, Subalpine and Olive-tree Warblers. Nearby woods hold Black, White-backed, Middle-spotted and Grey-headed Woodpeckers and the mountains to the east have Capercaillie, Nutcracker, Rock Thrush, Wryneck, Semi-collared Flycatcher and Barred Warbler.
Following heavy rains in the winter of 2010 - 2011, the Strimonas River changed its course to the south of the Vironia bridge, with the result that it enters the lake at an earlier point. This has cut through the embankment at site 3 in the site guide where it can now be a little tricky to turn the car around if there's been recent rain.
The new river channel has had a detrimental effect on birdwatching at site 4. Previously the shallow waters by the embankment were a favourite spawning ground for carp in spring, bringing huge feeding frenzies of pelicans, cormorants, herons and egrets close to shore. The new river course means that as the river enters the lake earlier the spawning grounds have gone as a result of the strong current.
Work to return the river to its previous course began in the summer of 2013.

The highlight of the month was the invasion of hundreds of Rosy Starlings which began on the 18th, with the arrival of a few individuals. The 19th brought more and, by the 20th, it seemed like every mulberry tree was alive with their movement and chatter. Many of the males were in full song between berry-gorging sessions. Plenty of Cuckoos and all four shrikes were in evidence, including good numbers of Masked.
The heavy spring rains have brought the lake to full capacity very quickly, causing the nesting attempts of the Great Crested Grebes to be twice washed out. Third time lucky hopefully. Of better news, over 200 Dalmatian Pelican chicks have hatched on the platforms and several pairs of both Glossy Ibis and Cattle Egret have bred in the drowned forest.
Of concern is the seemingly low numbers of large raptors, particularly Lesser Spotted, Short-toed and Booted Eagles, a phenomenon that seems not to be restricted to Kerkini.
Spring is here, some flowers have already bloomed and birds have already started their migratory trip. The White-tailed Eagles are noticeable around or in their nests. The Golden Eagles are carrying sticks to the same breeding nests they have used for years now. The Peregrines are flying near the nest they had used for years before the crows stole it last year. Maybe they are trying to take it back. The Dalmatian Pelicans with their bright colored beaks have already occupied two of the man-made breeding platforms while the third one that was constructed by the Kerkini Lake Management Authority, has already been adopted by several pairs. The Cormorants and first Grey Herons are sitting in their nests in the riparian forest. The first Little Egrets are here as well as a few Spoonbills, and the first House Martin. We noticed one White Stork on 21st Feb., 22 Ruffs on 25th Feb., and on 28th Feb., the first Lesser Grey Shrike. The Cranes increased to 29 on the 24th Feb. when a new group of 13 birds joined the initial flock. On 17th Feb., 57 Lesser White-fronted Geese arrived from Evros Delta and are getting ready for their big return journey to the Northern European countries. The White-fronted Geese are moving constantly looking for food. A pair of Long-legged Buzzard seem to have decided to stay in the region of Belles mountain for the time being at least. More than 10 Spotted Eagles along with 6-7 Marsh Harriers are looking for food near the riparian forest. The Great-crested Grebes have already begun their love games while the presence of three Oriental Turtle Doves has been the surprise of the region lately. Last but not least the Otters appear more often mainly in the North-eastern part of the lake while at the lower parts of Krousia mountain various mammals start appearing more regularly like roe deer, wild boar and wildcats.
During this February the Lake Kerkini Management authority made a total count of the birds in the broader area .These are some our results:
The Great crested Grebes are more than 900, around 4850 Cormorants, almost 500 Pygmy Cormorants, more than 500 Dalmatian Pelicans and 5 White Pelicans, one Cattle Egret, 42 Spoonbills, around 2000 Flamingo, 330 Swans were counted in total from the three species, around 800 White-fronted Geese, 57 Lesser White-fronted Geese and 45 Greylags. The Shelducks are more than 1400 and the Wigeon are more than 1000, the Teals and the Mallards are reduced but are still some thousands while the Pintails are at least 450. The Shovelers are almost 4500 while the Pochards are reduced to 3000 (among them a White-headed Duck). There are also more than 80 Goldeneye and 1200 Avocets. Large groups of small waders (>4500) and Black-headed Gulls (almost 8000)can be seen all around the lake.
Thanks to Kostas and the Management Authority for this data.
Around 5,500 Cormorants form large groups and look for their food in various parts of the lake but mainly in the mouth of the river.
The 3,000 White Pelicnas comprise the greatest number we have ever written down for the last years ( possibly the greatest number that has ever been recorded in Greece) .
The Dalmatian Pelicans have been more than 500 the same period of time.
There have also been two absent minded Squacco Herons , two young Purple Herons and three Night Herons who are a bit late for their migration.
We could also spot the last Glossy Ibis (14) at the Mandraki region and almost 500 Spoonbills in the shallow waters of the east and west part of the lake.
A White Stork and six Black Storks wander around the old riverbed of Strimonas river and the riverside forest and ten Mute Swans at the Trigono area.
The number of Greylag Geese remains 27 while there are ducks of every kind that someone can notice this time of season.
As prey birds are concerned the White-tailed Eagles, the last Lesser Spotted Eagles, Short-toed Eagles and Booted Eagles as well as Marsh Harriers, Peregrines and other smaller prey birds (Sparrowhawks, Goshawks, Kestrel etc) look for their food around the lake and mainly in the north part of the lake while in the forest there are more than fifteen Crows.
There are more than 4000 Coots , almost 800 Avocets , some hundreds of Lapwings and very many riverside birds in the east and west part of the mouth of Strimonas river. There are also more than 500 Yellow-legged Gulls, more than 6,000 Black-headed Gulls and 2500 Flamingos.
Two Cranes continue to stay in the same region up till now and along go three Egyptian Geese (they probably escaped from a park).
The first six Spotted Eagles presented themselves at the National park on 6 October .The same day we had the arrival of the first group of 29 Lesser White-fronted Geese –lwfg-(among them a family with 5 young birds) on the northeastern part of the lake. This date has been the earliest arrival of this species for the last few years in the region.
The White Pelicans gather in large groups and try to find rising currents to migrate.
On 8 October another group of 5 lwfg was added to the existing population that has now reached the number of 34.
In the middle of October we noticed an adult pair of White-tailed Eagle and a second pair with an adult and subadult individual.
The Spotted Eagles have been already more than ten maybe twelve individuals while the Marsh Harriers have been of a similar number.
A group of around 22 lwfg arrived at the region and is added to the existing group. The number of the species has reached 56 up till now.
After the middle of October we observed the presence of various smaller prey birds like Hen Harriers, Merlin and one or two passing by Hobby.
The presence of Rock Partridges, Woodcocks and a few Thrushes has been noticed on Belles mountain.
Around the end of October the first pair of Red-crested Pochards appeared at the region Trigono and one young delayed but very friendly Cattle Egret presented itself and has remained in the region near a herd of cows daily.
Everyday around 3000 Flamingos feed themselves in the east embankment.
Twelve Glossy Ibis remain in the region and on 28 October we noticed for the first time a group of around 110 White-fronted Geese and the first 6 Bewick’s Swans swimming in the waters of our lake.
The first Lesser White-fronted Geese arrived on 5th, with a group of 10, and these increased to 56 on 20th.

It is worth mentioning the successful breeding of a pair of Golden Eagle that used the same nest as previous years. This year some 190 Dalmatian Pelicans (a record number!) were born in the 130 nests that we counted on the artificial platforms especially constructed by the Management Authority for this reason. This year we had the successful breeding of at least 9 pairs of Common Terns that took place on the small platform (it had been constructed by the Authority Management of Kerkini lake and the financial support of two very good friends, Steve and Hilary.
We had the chance during the night to watch some mammals like badgers, ferrets ,weasels, jackals, young foxes even wolves while during the day we could come across hares, roe deers and wild boars.
During the month of August we had some important recordings of various birds :White Pelicans (>1500), Dalmatian Pelicans (>550), more than 650 Pygmy Cormorants,at least 20 Cattle Egrets, around 1500 Little Egrets,250 Great Egrets, 40 Purple Herons, more than 300 Grey Herons, around 800 Spoonbills, more than 400 Flamingo (we are expecting the arrival of more in due time), 40 Greylags (the young birds are included), more than 15.000 ducks of all kinds that someone can watch this time of year.
As the big birds of prey are concerned we can observe Short-toed Eagles, Lesser spotted Eagles, Booted Eagles and other birds that live and breed here like Golden Eagles and White-tailed Eagles. Recently many Harriers have been observed in the shallow waters of the lake (even today I counted 9 Marsh Harrier that were hunting in the area of the river mouth ). The Coots are many thousands while there are a lot of Black-winged Stilts, Avocets, Lapwings and Plovers in the mud lands. There are also Black-tailed Godwits (at least 350) and other wader birds in big groups ( as it is the migration period ).We can also watch seagulls in great numbers and Black-headed Gulls more than 5000 while the Yellow-legged Gulls are around 700.
The lively picture of the Kerkini region is completed by the presence of the last Glossy Ibis, few Squacco Herons, Night Herons, Black Storks, the first Wood Pigeons and very many small birds like Wagtails, Thrushes, Shrikes, Warblers, etc.

June has started hot and humid with regular thunderstorms in the late afternoons. The water level rose quickly this spring and as yet (9th) there isn't sufficient surface vegetation for the Whiskered Terns and Black-necked Grebes to begin nesting. There are, however, plenty of all four herons, Little Bitterns and Little Egrets with just a few Cattle and Great Whites. Masked Shrikes are the most numerous that we have known, but the Lesser Greys are absent from their regular track near the river, perhaps spooked by a pair of nesting Buzzard which has three chicks. A flock of 40 Eleonora's Falcons was near Vironia bridge and Short-toed, Booted, Lesser Spotted and Golden Eagles are fairly easy to find.
