No let up in winter flood

It’s hard to believe that it’s late February already. Over the past few weeks instead of flood levels receding, they have been getting even higher and we are currently in the grip of a very high winter flood.

Winter waterbird flocks are still around, although the high water levels can make them difficult to get close to. Often they are far out on isolated islands of high ground, with only a few stragglers close by the water’s edge. They also tend to be more dispersed over a larger area, again making it more difficult to get good views.

Of note a number of Ruff have turned up on Tower Callow. There are also good numbers of Black-Tailed Godwit on “The Commonage” on Bullock Island, a good birding spot, even when water levels are high.

The predator fence on Inishee is still very much under water. It will probably take about three weeks before water levels are low enough to begin working on it and by that stage the pressure will be on to get the work done before Lapwing, Redshank, Curlew and Snipe return to breed. Fingers crossed no serious damage has been caused by the prolonged summer and winter flooding.




As the sun goes down

Today is the winter solstice and in some respects the end of the year.  However, large wintering waterbird flocks will remain in the Callows right through the Christmas and into the New Year, before starting to disperse around late February to head to their breeding grounds.

If any of you are in the area, in addition to the Commonage at Bullock Island near Shannon Harbor (http://www.birdwatchireland.ie/Default.aspx?tabid=219), the Little Brosna is also a great place to see large wintering flocks and even some less common species.

The other day I had 162 Pintail, 45 Shoveler, 27 Tufted Duck,  11 Little Egret,  and nine Gadwall. I’ve never seen so many of these species in one place before, so it was a lovely surprise. There were also large flocks of Wigeon, Teal and Lapwing around. It’s well worth a visit over the Christmas, you never know what else might turn up.

From here on in, days will start getting longer and thoughts will slowly turn to spring. Come January I begin organising maintenance works on the predator proof fence on Inishee. If you think you’d be interested in lending a hand, go to http://www.birdwatchireland.ie/Jobs/tabid/71/Default.aspx for more details.

I’d like to take this opportunity to wish you all a very Happy Christmas, and all the best for 2013. I hope you have enjoyed this year’s blog and look forward to keeping you up to date with next year’s happenings in the Shannon Callows.

Winter in the Callows

After a brief spell, when flooding subsided, the Callows are once again under full winter flood. Unlike in summer, when flooding leaves the Callows eerie and silent, in winter they become a hive of activity.

Large wintering flocks of Golden Plover, Black-tailed Godwit, Lapwing, Teal and Wigeon arrive, along with other species such as Curlew, Redshank, Dunlin, Shovler, Pintail, Whooper Swan and Black Headed Gull. And it’s always worth keeping an eye out for rarer visitors, such as Ruff, American Wigeon and passage Greenshank.

When water levels are high, as they are now, sites like “The Commonage” between Banagher and Shannon Harbour are excellent spots to see all the above, and often provide opportunities to get quite close to birds.

It’s also a great place to try and spot colour ringed Black-tailed Godwit, which turn up occasionally. A few years ago I had seven on one visit!  Sending the records to the Schools Godwit Project, and finding out exactly what that bird has been up to for the past few years, is both exciting and extremely useful in helping researchers gather important information on the species.

The I-Webs season is now well underway and two counts have already been carried out on the Little Brosna. It’s a daunting task because as winter progresses, it holds huge numbers of birds. Indeed it’s an internationally important site and one of the most important in the Country, often holding more than 20,000 wintering waterbirds.

The summer that never was

Although it felt like summer never actually started, it’s now well and truly over here in the Callows.

Wintering flocks of Curlew have started to arrive back. Always the first, they really mark the end of summer in the Callows.  

The farmers participating in the Breeding Wader Grant Scheme (BWGS) have already set their sights on next year’s breeding season and are now involved in preparing the habitat on their land for it.

Despite all the rain and the flooding waders did well in the Callows this year. They were extremely lucky, had flooding occurred a week or two earlier, it is likley that breeding would have completely failed. Other species, including the later nesting Corncrake were not so lucky, and it will be next year before we see the true impact of this summer’s flood. Will there be a Corncrake in the Callows at all?

Last year and for the first time since 2008, wader populatins on BWGS land declined; most likley a result of the harsh winter of 2010/11. However, breeding was sucessful for many pairs and on the back of this success numbers were up again this summer. This year hatching and fledgling success continued to increase - up by 117% and 146% respectively on last year’s figures. Hopefully this should result in an even bigger population increase in 2013.

On Inishee, the final tally was 38 pairs of Redshank, eight pairs of Lapwing and 11 pairs of Snipe. All but one pair of Snipe successfully fledged chicks. The Curlew, originally recorded on Inishee, moved to a quieter spot across the river to breed and managed to fledged two chicks. As the population continues to rise on this island, birds will eventually spill out into the surrounding land and start new colonies.

The fence also provided good nesting habitat for other species.

I’ll continue to update this blog throughout the autumn and winter months, and follow the Callows progression from an important wader breeding site to a major wintering site for waders and waterfowl.

The End of Corncrake in the Callows?

Flooding continued to get worse since the last post

The last Corncrake in the Callows is unlikely to breed successfully this year. Double brooded, its first nest would have been washed away. It should be on its second brood of eggs now, but all suitable habitat is under water. For such a short lived bird (3 years) failure to successfully fledge two broods can have devastating impacts on its population. Our bird is unlikely to fledge any young this year. The farmers and conservationists are devastated – could this be the last Corncrake in the Callows? We won’t know until next year…. it’s going to be long wait.

Inchinalee Island is now nearly completely under water. Luckily the famer managed to swim his cattle off safely. Against all odds, the Redshank fledged its chicks and flying juveniles were seen last week on the adjacent mainland.

Breeding has finished on most sites and the birds have left. Their absence and the silence is a little eerie, especially on Inishee.  Apart from a few Redshank, which should be gone this week, Snipe are all that is left. They have a longer breeding season than Lapwing, Redshank and Curlew and surveying will continue for another few weeks on their sites.

We turned up a new Snipe nest on Inishee last week. 

Hanna the Breeding Wader Fieldworker finished up last week. A big thank you to her for all her hard work. It’s been a difficult season and I’m sure she never imagined she’d spend so much of her summer wading through food waters!

More Rain and More Flooding

The summer flood has progressively got worse since my last blog and is now the worst summer flood that I’ve experience in my eight years working on breeding waders in the Shannon Callows. Flooding is now at proper winter levels.

Inishee Island is partially under water and I’ve had to turn off the predator proof fence. The water levels in some sections are so high they are interfering with the electric current and there's a risk that it could blow the fencer unit.

The flood has meant that I can't get to some of our island sites. Luckily Mark the NPWS predator control operative was able to give me a lift out to these sites.

Inchinalee Island, up near Athlone is nearly completely under water, the cattle stranded on what is left of the island. The distance to shore has increased from about 30 to over 500 meters and the current is so strong that swimming them off the island is impossible, for now. They have enough grass, but if flood waters persist or rise the farmer will have to provide them with additional feed or find some way of getting them off the island. Amazingly the last remaining pair of Redshank managed to sucessfully hatch its chicks in the worst of the weather and the male is continuing to raise them.

Although there have been wader nest losses, we have been lucky. Many sites had already fledged or hatched their chicks before the flood rose. Inishee has done amazingly well despite the weather, probably because the chicks were already a few weeks old before the worst of it hit. Splashing through puddles this week we turned up 27 Redshank, seven Lapwing and five Snipe fledglings.  Breeding is still ongoing for 16 pairs…. hopefully predators will stay away even though the fence is off.

We’ve been helping out with the Whinchat survey and although many areas are inaccessible we have turned up a number of breeding pairs in meadows that are nearly completely under water.  We’ve even recorded some birds carrying food to chicks, so some at least are surviving.

A Summer Flood

Poor weather in summer puts everybody in bad form, but for the Callows farmers and its wildlife it has a real impact.

Last week it rained for over 48 hours straight, in some parts three inches falling in just a day. Wader chicks would have been unable to feed, the adults having to brood them constantly to keep them dry and warm. Young chicks would have suffered the most and anything unlucky enough to be hatching during this period is unlikely to have survived.

Anyone who saw the BBC’s Spring Watch on Monday would have seen the devastation that prolonged heavy rain can have on young Lapwing.

The river Shannon drains a fifth of Ireland and when heavy rain is experienced nationwide, as was the case last week, much of the water makes its way into the river system. The Callows are now under a summer flood, its true extent hidden by the long meadow grass. Nests will have been flooded, chicks displaced and the farmers have lost their grazing land, in a year when grass has been in short supply. If the flood persists, they are in danger of losing their winter fodder – the grass in the hay meadows will simply rot.

It may be weeks until we can assess the extent of the damage. Some sites are inaccessible and we have been unable to survey them, while on others we can only carry out a partial survey.

Thankfully the Corncrake meadow is not yet under flood, although there is a risk of further flooding as more heavy rain is forecast.
