Resolutions and Solutions


We are now well into the New Year but it is by no means too late for resolutions. Waterford has an immense variety of and richness in its wildlife so make a decision now to get out and enjoy and experience some of these opportunities during the current calendar year.

So what can we expect?

Birds

Cattle Egret by Richard Zamora
Historically just over 300 different species of bird have been recorded in Waterford. In the last five years the numbers of different species recorded have been 187 (2013), 197 (2012), 203 (2011), 194 (2010) and 185 (2009). On the 4th of January 2014, 112 different species of bird were recorded in Waterford on that single day.

Opportunities abound to see birdlife in the county and the following are some suggestions:

Spoonbill by Fran O'Connell

Dungarvan still hosts the overwintering spoonbill. Check out Ballyneety for the spectacular male goldeneye and accompanying dowdier females. Over the past several weeks two cattle egrets have taken up residence in the Bunmahon/Seafield area - southern Europe or Africa would be their more usual winter home. The boating lake at Tramore is presently affording close-up views of shovelor, gadwall, tufted duck and snipe along with numerous gulls and other wildfowl. 
Ring-necked Duck & Tufted Ducks by Bernie Sheridan

A careful search through the gulls should yield the North American ring-billed gull and an Artic glaucous gull. A male ring-necked duck is currently wintering at Ballyshunnock reservoir.



Kingfisher by Richard Zamora

A check out of the bridges crossing the rivers at Ballyvoile, Stradbally, Bunmahon and Annestown (among other rivers) should yield a dipper and perhaps a colourful kingfisher.

During spring/early summer a visit to the foothills of the Comeraghs or The Vee should produce a cuckoo. The distinctive call is obvious and with patience it should be possible to observe the bird itself.

In late April whimbrel migrate through Waterford on their way north to their breeding grounds. In some years literally thousands of these birds linger on the beach at Clonea as they feed up before resuming their journey northwards.
Whimbrel by Andrew Malcolm

Spring also offers the opportunity to experience the famous Dawn Chorus. At dawn numerous different species of bird sing loudly to proclaim their territories and re-establish contact with each other. Organised outings take place in Waterford and although it means an extremely early start it is well worth the effort.

Dipper by Fran O'Connell
In July/August watch from headlands such as Helvick and Brownstown during storms for seabirds pushed close to land by strong winds. Numbers passing can be spectacular and include shearwaters, skuas, auks, terns and other species.




Insects

With the warmer weather in spring insects make their appearance. Watch out in March and April for the spectacular male orange tip butterfly. A visit to Coumaraglinmountain in May/June should provide an opportunity to observe the green hairstreak butterfly. Its much rarer relative the purple hairstreak can be seen fluttering around the tops of oak trees in August/September. Colligan and Ballyrafter are good sites for this butterfly. The ideal habitat is the canopy of oaks overhanging streams. A visit to Mount Congreve may be rewarded with a comma – a recent Waterford coloniser.

The area between Annestown and Dunhill castle is excellent for emperor dragonfly and brown hawker in summer. Watch these large insects as they hunt and defend territories, resembling miniature helicopters as they fly to and fro.

Mammals
Fox by Andrew Malcolm

Everybody admires red squirrels and they are widespread in Waterford. The Towers at Lismore and Colligan Woods are good areas for the species. Pine martens are rarer and much more elusive but are present in the Kilrossanty and Portlaw areas. Watch the fields throughout the county at any time for foxes hunting.



Common Dolphin by Andrew Malcolm
Bats are also widespread in Waterford. Watch any waterways at dusk in the county
during spring/summer for the daubenton’s bat. Street lights attract leisler’s bats at night where they can be observed feeding.
Minke Whale by Andrew Malcolm

Harbour Seals by Bernie Sheridan
The Waterford coast is fast gaining a reputation as one of the foremost places in Europe for observing marine mammals. Fin whales (the second largest animal to ever exist on the planet), minke whales, humpback whales, bottle-nosed and risso’s dolphins are easily observable in season. Ram Head at Ardmore, Helvick Head and Tankardstown at Bunmahon are excellent vantage points. Dungarvan Harbour holds small numbers of
both grey and harbour/common seals.

MUD GLORIOUS MUD AND WADERS


High Tide Wader Roost by Richard Zamora
Waterford being a coastal county has large areas of estuarine mud. At first glance mud may seem to be a degraded habitat devoid of all life. Happily this is not the case. Estuarine mudflats are considered one of the richest habitats in the world. The mixture of fresh and salt waters, with abundant nutrients and organic materials supports an extremely abundant invertebrate resource. This food concentration is extremely important to birdlife, particularly waders.

Lapwing by Colum Flynn
Waders, or shorebirds in American parlance, generally occupy wet places where they probe for food such as molluscs, snails, worms and other invertebrates. Waders include a large number of different species characterised by different bill and leg lengths. This allows each species to probe at different depths in the mud to locate prey, thus avoiding direct competition. It also guarantees that the prey species can survive in sufficient numbers to ensure continued existence.

Waterford is of vital importance to wader survival in two respects –
Long-Billed Dowitcher by Liam Cahill
overwintering birds, and passage migrants.

Large numbers of waders choose Waterford to overwinter. Their feeding is dictated by the tides. Waders only stop feeding at high tide when the mud is totally covered. Night-time is not an obstacle – they simply continue probing for food during the hours of darkness.

Whimbrel & Grey Plover by Pat Veale
Waders are long distance migrants moving in spring to their breeding grounds in the far north from their over-wintering areas here, in Southern Europe and Africa. In autumn they reverse their migration along with their progeny. These journeys are not done in one step. The waders stop off at traditional feeding areas upon which they have become dependent over millennia. They feed at these staging posts before continuing with their onward migrations. Any loss or damage to these feeding areas would be catastrophic to their wellbeing. Whimbrel, migrating to their breeding grounds and stopping on the way to feed in Waterford in late April, is an excellent example of passage migration.
Dunlin by Fran O'Connell

Black-Tailed Godwit by Colum Flynn
The following illustrates the absolute importance of Waterford to waders as a winter refuge in terms of numbers: Dungarvan is internationally important for black-tailed godwit and nationally important for oystercatchers, golden plover, grey plover, knot, dunlin, bar-tailed godwit, greenshank, redshank and turnstone. Tramore is nationally important for golden plover, grey plover and black-tailed godwit whilst Waterford Harbour holds nationally important numbers of oystercatcher and black-tailed godwit. The Blackwater Callows are internationally important for black-tailed godwit and nationally important for curlew.
Lesser Yellowlegs by Colum Flynn

Occasionally Waterford plays host to rare American waders (shorebirds). At different times long billed dowitcher, American golden plover, pectoral sandpiper, lesser yellow-legs and semi-palmated sandpiper have graced the Cunnigar.

Sanderling by Fran O'Connell
Viewing waders in Waterford is easy. Bar-tailed and black-tailed godwits are readily located in large numbers on estuarine mud virtually anywhere within the county. Turnstone get their name from their habit of turning over stones and seaweed to locate prey. Dunlin are the ubiquitous small wader often in large flocks. Both dunlin and turnstone are widespread throughout Waterford. Watch out for the small grey sanderling feeding along the tideline.
Turnstone by Andrew Malcolm


Curlew by Liam Cahill
 Sanderling resemble toy soldiers as they advance and retreat with the breaking waves. High tide roosts present an opportunity to view different species in close proximity and to study the varied sizes and plumages. Look for and listen to the widespread lapwing with its distinctive pee-wit call. The long de-curved bill of the curlew is unmistakeable, coupled with its plaintive ‘curlew’ call. 

Look among the wader flocks for the plump, stubby billed, medium sized, pale coloured grey plover. The grey plover is easily recognised by its dark axillaries (armpits) once in flight.
Redshank by Andrew Malcolm


 Both redshank and greenshank are common throughout Waterford and best recognised by their respective leg colouration and easily recognisable calls.

WHERE ARE ALL THE BUTTERFLIES DURING WINTER?


Peacock by Fran O'Connell
Butterflies cannot survive our winters as flying adults due to the cold and lack of food. To survive the adverse winter conditions, most but not all, species of butterfly hibernate. Thus most species of butterfly are all around us during the colder months of autumn, winter and spring. However, dependent on the species, they adopt a variety of different strategies to survive until suitable conditions return.



Painted Lady by Daniel Wheldon
MIGRATION
Amazingly, just like swallows and warblers, some species of butterfly migrate south to Africa to avoid our
Small Tortoise Shell by Bernie Sheridan
colder months. Red admirals, painted ladies and in some years clouded yellows migrate in summer from Southern Europe and Africa to Ireland. It was once considered that most, if not all, died with the onset of colder weather. However, radar studies have now proven that these species are capable of a reverse migration to sunnier climes in Africa. These epic journeys involve thousands of kilometres which is truly phenomenal for such a tiny creature. The numbers involved in these movements can run to millions of individuals.

Comma by John Joe & Liam Cahill
ADULTS
A number of species including small tortoiseshells, peacocks and commas hibernate as adults. These species build up sufficient fat reserves during summer/autumn to enable them to survive the long colder months. They seek out suitable niches in trees, buildings, crevices etc. and hibernate. Most people will be familiar with small tortoiseshells hibernating on the walls of their homes. If you come across a hibernating butterfly it is best to leave them well alone to sleep.


 CHRYALIS/PUPAE
Wall Brown by BernieSheridan
This is the stage between the caterpillar and the flying adult butterfly. The chrysalis spends the winter at the base of plants or underground thus avoiding the worst of the winter weather. When conditions improve in spring/summer the chrysalis metamorphoses into the flying adult butterfly. Large whites, small whites, orange-tips and holly blues among others adopt this policy.

Common Blue by Fran O'Connell
CATERPILLAR/LARVA
Many species spend the winter as caterpillars. The advantage of this strategy is that, being mobile, caterpillars can hunker down in deep cover in adverse conditions and emerge to feed at opportune times. A caterpillar can also move to avoid flooding, predators and other dangers. Common blues, small coppers, fritillaries, wall browns, gatekeepers, meadow browns, small heaths and ringlets use this strategy.



EGGS
Small Copper by Bernie Sheridan
The purple hairstreak over-winters as an egg. The eggs are laid in July/August. The Caterpillar quickly develops within the egg, immediately hibernates and does not hatch until the following April. The caterpillar then feeds on the emerging buds of oak trees – its only food source. Oak leaves contain tannins which are poisonous so early feeding on the buds may avoid this hazard.





Silver-washed Fritillary by Fran O'Connell
THIS YEARS BUTTERFLIES
The spring/early summer being wet and relatively cold was not conducive to butterflies. Species such as orange-tips, green-veined whites and green hairstreaks seemed to be flying in reduced numbers. As the summer progressed and the weather grew warmer conditions became optimal for adult butterflies. Large numbers of whites, red admirals, peacocks, silver-washed fritillaries and common blues were on the wing. Wall browns were in good numbers in suitable habitats and the beautiful small copper very much in evidence. 

After a number of poor summers this augurs well for the future wellbeing of butterfly populations.

Commas consolidated their expansion into Waterford with multiple additional sightings in the Mount Congreve area.

RECENT WILDLIFE SIGHTINGS
The spoonbill has returned to Dungarvan for yet another winter as have a number of long-tailed ducks. A new surf scoter is presently overwintering in Dungarvan harbour and a number of yellow-legged gulls are on the Colligan River at Ballyneety.

Fin and minke whales, common dolphins and porpoises, harbour/common seals, grey seals and otters are presently being encountered along the Waterford coast.

Watch out for returning thrushes such as redwing and fieldfare over the next several weeks.
