The last egg and the Norwegian Blue Parrot



We're delighted to announce that the last Little Tern egg has hatched. 111 Little Tern pairs successfully hatched young this year, more than any other year since the project began. We have a total of 213 chicks, most of which have fledged. Little Tern numbers in the colony are noticeably smaller as they start to leave the colony so the season is well and truly winding down. The only small concern we have is a Peregrine Falcon that pays the colony a visit every other day, we've seen it take at least 3 birds this year but given how quick they are the number is likely to be higher. However we are not too worried as they do not take many and it would be foolish to think that we can protect every individual.

The Otters have been ever present this year and we often watch them hunt and play from our caravans. They seem to be particularly fond of crabs, munching loudly on them all night. Birds appear to be on the move now and we've had good numbers of Black-tailed Godwits, Curlew and Common Sandpipers  show up in the lagoon. Willow Warblers can be seen passing through the Buckthorn and a pair of Wheatear were spotted in the colony yesterday. We were also lucky to see a Red Kite glide past the farmland last week. Yesterday our first Clouded Yellow of the year in Kilcoole made an appearance. Clouded Yellows are a migrant butterfly that comes all the way from Spain/North Africa. Some years they can be very scarce and some can be just the opposite, like the Waxwing, so here's hoping we have a good Clouded Yellow year. They are unmistakeable bright yellow butterflies that are a joy to see.

In recent years in Kilcoole we leave a little joke around the colony. Last year we put a plastic owl on a fencepost near the caravans. It was almost heart breaking telling excited onlookers that it was plastic! One year on our species board we had Unicorn listed. To our surprise this did catch one person out! This year we went for a more subtle approach. On our species board we listed "Norwegian Blue Parrot (dead)". This was lost on most people and it didn't seem worth it. We had many people asking us where we saw it and how it got here. But it was all worthwhile (to me anyway) when I saw a couple of people delighted with themselves after getting the joke. After which the flood gates opened and more and more passers by gave me their approval. The parrot is a reference to the infamous Dead Parrot Sketch performed by the legendary Monty Python gang - https://www.youtube.com/watch?v=4vuW6tQ0218. And it wasn't dead, it was resting.

Unsung heroes: Volunteers

There are 5 Little Tern eggs left to hatch in Kilcoole and 212 chicks of all sizes. It is an excellent time to come and visit the colony as there are fledglings everywhere learning to fly and hunt. We have counted a minimum of 86 fledglings on site which is excellent, we suspect some of the older chicks (Juggernaut and friends) have moved out of the colony to somewhere else along the east coast, or beyond. Many of the chicks are pretty advanced and have darker crowns than their younger cousins. They're still a bit clumsy in the air and haven't mastered the art of diving like their parents. We often see them hunting close to the surface and then bellyflop into the water after a fish without success. However, Little Terns learn quickly and they will be making their way to Africa, for the first time, very soon. The Bray airshow was on recently with many of the planes practising in the Kilcoole area, it was amazing to see but even the most elaborate aerial displays by the stunt planes were no match for the grace and aerial prowess of the Little Terns! We are delighted with the progress of the terns and so far everything is going according to plan. Touch Wood.

It has been very exciting to be involved in a record year and we are extremely grateful to our volunteers for all their hard work and dedication. Since the project began in May we have had an overwhelming response from volunteers and their help has been integral to the successful running of this project. What is incredible is the contrast in our volunteers. We have teenagers fresh from doing the Junior Cert to old age pensioners helping us out on the beach. We also have volunteers that are expert birdwatchers and skilled researchers in wildlife conservation as well as volunteers who are beginners and don't even possess a pair of binoculars. One of our volunteers Seán Kelly is a PhD student in Trinity College Dublin and was recently the centre of media attention after the publication of his paper in the scientific journal PLOS ONE. Seán has spent the last few years looking at bird speciation in Indonesia and his paper classes the Wakatobi Flowerpecker as a full species for the first time! Like all great discoveries this story ended up on the cover of the Metro newspaper, it also appeared in the Irish Times, Independent and countless websites and Seán was interviewed on the radio and television. We were all delighted at how well Seán's work has been received and we had more than a few members of the public asking us in Kilcoole about the Wakatobi Flowerpecker. For the full story and a link to the paper check out this article - http://www.headstuff.org/2014/06/reclassification-bird-species-matters-introducing-wakatobi-flowerpecker/wakatobi-flowerpecker-nlb/. Another volunteer, Des Higgins, was also in the limelight recently as he was named as one of the most "influential names in science" and in the world's top 3,000 researchers for his work on the Bioinformatics tool Clustal. Find out more here - http://www.ucd.ie/news/2014/07JUL14/020714-Two-UCD-researchers-among-most-influential-names-in-science-according-to-Thomson-Reuters.html. Des had to get a taxi down when he volunteered last time as he thought we would be late, dedication!

Ignore the jail and hammer headline!

Many of our volunteers are students in Tralee, Cork and Dublin etc. who are trying to put their summer to good use and we also have volunteers from a wide range of occupations who squeeze in some hours at weekends or after work. Some people go to great lengths to get here spending hours on public transportation and walking to get here and occasionally helping out in horrid weather (we don't expect this from everyone!). There has also been a multicultural array of volunteers this year with people from France, Lithuania, Peru and Poland (to name but a few) helping us out! All of our volunteers do share one thing in common and that is they have all helped in the conservation of a beautiful and endangered bird as it does not matter who you are or how qualified you are you can still play an important role in this project. Regardless if someone has helped out for an hour or for a whole season we are extremely grateful and we would find it very difficult without the help! We are also particularly grateful to the volunteers that donate chocolate to the project. Last week I carefully left a KitKat chunky in the Buckthorn so I could run off and do something else. When I returned it was gone, I was convinced it had been stolen until I caught a glimpse of the shiny foil of the packaging in the corner of my eye. A rat had taken my KitKat and devoured it, devastation and surely one of the biggest losses of the year in Kilcoole. After hearing my tale of woe a volunteer generously donated some chocolate to the project. So there you have it, volunteers, what a great bunch they are. Thank you.

P.S Our e-mail account littletern@birdwatchireland.ie stopped working recently, we are trying to fix it. Apologies for any inconvenience caused, you can e-mail me at powera2@tcd.ie.

200 chicks, colour ringing and Moths!

This year has been all about records. We have reached 2 milestones in the last week, we now have 208 (!) chicks on the beach with 13 eggs left to hatch and today we colour ringed our 100th chick! The numbers are extremely high and the colony is buzzing at the moment with plenty of fledglings in the air and 113 active pairs of Little Terns.

This is the first year we have colour ringed Little Terns  in Kilcoole. We put metal rings on every Little Tern chick that hatches in Kilcoole (and have done so for many years) and they can be put on the chick when they are only a couple of days old as their leg doesn't change in diameter as they get older. We can only put colour rings on Little Tern chicks that are a couple of weeks old as colour rings are longer and we have to wait for the chicks legs to stretch out a bit first. Chicks start to leave the nest after 2 or 3 days so finding old enough chicks to colour ring is a little more difficult than metal ringing. At that age chicks congregate on the foreshore and, unlike their younger cousins, can run! So when we look for suitable birds to colour ring we usually end up catching a big group of them at once. The fact that we have colour ringed 100 out of 208 birds is incredible and it also gives us a good indication that many of the birds have survived the first 2 weeks, bearing in my mind that a fair chunk of the birds are not old enough for colour ringing!

Even though the Little Tern is a flagship species there are still many mysteries surrounding it's migration behaviour. We know they go to west Africa but west Africa is a big place and we are not certain what their migration routes are. We know that Little Terns move between sites, a dead adult tern was found last year in Baltray that was originally ringed in Kilcoole in 2010 and an adult bird was trapped on the Isle of Man last year that was also a Kilcoole bird ringed in 2010. We hope that colour ringing the birds will allow us to see the extent these birds move between sites. Colour rings are far more visible than metal rings and we hope this will lead to many re-sightings, especially considering that many Little Tern sites are actively wardened. We also hope that more re-sightings will happen along their migration routes. Most adult Little Terns are metal ringed but it is impossible to read the code from a metal ring, without catching an adult or finding a dead bird, so we don't know where they originated. This will not be the case with colour rings as the code is much easier to read but even if it is not possible to read the ring we can still get extremely useful information simply from the colour of the ring and what leg it is on. We are using green colour rings in Kilcoole with white writing on the left leg of the Little Tern. They are also colour ringing in Baltray and putting green colour rings on the right legs of the Little Tern. A colour ringing scheme is also underway in the Isle of Man where they are using yellow rings. Hopefully other tern colonies will follow suit and keep colour ringing for years to come as it should provide excellent long term data. Understanding everything about a species can be vital for determining it's conservation requirements. We can do everything we like to save a migratory species in our own country but if they are being killed in their wintering grounds it could count for very little. Hopefully this scheme will help us see the bigger picture. So remember if you see a colour ringed Little Tern report it!

And now for something completely different....
 
Stephen McAvoy paid us a visit last week and brought along his Moth trap. I was very lucky to see some real beauties before he let them back into the wild. The Poplar Hawk moth looks like it could devour a tern!

We have lift off.....



It's hard to believe that it is already mid July, the season has really flown by. But it's not the only thing flying in Kilcoole as the first wave of Little Tern chicks have begun fledging! The first chick, K1, was first seen in the air on the 4th of July (celebrating independence day) and the rest are starting to follow suit. We almost have the full range of Little Tern age groups on the beach now with 20 eggs left to hatch, 194 chicks of all sizes (getting close to the magic 200!) and, of course, the adult birds themselves. The only thing missing is a 2nd calender year bird which is a rare occurrence in Ireland. 2nd calender year Little Terns do not breed and tend to stay in Africa during the summer instead of migrating back to Ireland. However there is one or 2 knocking around in Baltray in Co. Louth. http://www.irishbirding.com/birds/web/Display/sighting/69114/Little_Tern.html

Each stage of the season has different and unique challenges. Bird of prey activity has skyrocketed in the past couple of weeks. A juvenile Peregrine Falcon has frequented the colony practically every day for the past week and sometimes comes in 2 or 3 times a day. Luckily, the juvenile Peregrine is still learning it's trade and hasn't managed to pick any off any just yet. However, an adult Peregrine took out an adult Little Tern over the colony on the 7th of July. There is nothing we can do to prevent a hit and run predator like a Peregrine Falcon attacking the colony. It is the fastest bird in the world after all! Fortunately they do not tend to take many birds. Peregrine Falcons employ an almost cheetah like strategy where they use an incredible burst of speed to attack the colony and single off an individual bird. Little Terns are also master aviators and are usually capable of avoiding such attacks. Kestrels, on the other hand, will come to the colony and hover looking for the chicks. This gives us time to chase them off using state of the art anti-Kestrel technology (see below pic). If you ever see a warden running down the beach banging a frying pan and a saucepan together do not worry we haven't gone crazy (although that should not be ruled out!) we are just trying to scare off the Kestrel. Luckily we have only had to do that once this year. The Kestrels have not yet copped that there are chicks on the beach and hopefully it will stay that way. We have had occasional glimpses of Sparrowhawk (which took an adult Little Tern last year) and Long-eared Owl but they have not yet posed any threat. We have spotted a Fox on the beach on 2 occasions well north of the colony, snooping around, but it hasn't taken any notice of the terns.

So, all in all, everything is going according to plan. If the wee chicks can get through the next 3 or 4 weeks unharmed they will begin their journey back to Africa. We will be here, doing our best, to make sure that they get that far.

Chicks, chicks and more chicks!

Wow, what a busy couple of weeks we have had in Kilcoole! Apologies for the lack of recent updates, the beach has really come alive since our last blog post. It is a minefield out there with new nests still being found and chicks running riot. We now have an army of 150 chicks on the beach with a further 90 eggs expected to hatch! It's a great and busy time to be a warden and we are thankful that the good weather is holding up.

On the 19th of June, after the Spring tides, disaster struck the colony. A mild easterly combined with a high tide was enough to flood the foreshore and it effected almost 30 nests. 10 nests were destroyed completely and it was horrible seeing random eggs washed up in amongst the seaweed. Some nests were completely submerged but stayed put, others were carried by the tide into different locations (and later regathered by the adults) and other nests lost some of their eggs. However, Little Tern eggs are resilient and it was with great joy that we watched the majority of the tide effected nests hatch in the past couple of days. Needless to say that chicks are much better than eggs at avoiding the tide!

Some of the chicks hatching are incredibly small, the smallest chick to date hatched today and weighed a mere 4.57 grams. The first chick to hatch (K1) which is the largest one by some distance (nicknamed Juggernaut) has walked about 400 metres north and out of the colony protection. It may be the biggest but not the brightest! Hopefully it will go undetected outside the colony and fledge successfully. Unfortunately we found 2 more nests far outside the main colony, 1 with chicks and 1 with eggs. Sadly there is not much we can do in this situation so we ask any people walking the beach to try and stay on the path or at least be mindful that not all the terns are in the safety of the fencing!

We would not be able to stay on top of all the work here in Kicoole if was not for the help of our volunteers. We are very grateful for all the hours they have put in and it really makes a big difference to our efforts here! So, all in all, things are looking very good in Kilcoole. Regardless of what happens with the rest of the season we know that the Little Terns are doing well by the record numbers here and in Baltray. It is a great time to come down and see the colony so why not pop down for a visit?

The first chicks and a record year!

It happened. The record has been broken. There are an astonishing 108 active pairs of Little Terns in Kilcoole. The previous record was 106 pairs in 2006. Incredibly, we are still finding nests and are expecting some more to relay. We were agonisingly stuck on 99 nests on Saturday the 14th of June but we completed the century with a tentative single early Sunday morning. This was perfect timing for the hugely successful Carlow and Wicklow Branch of BirdWatch Ireland outing later in the morning. Darren and I were both involved with the Baltray Little Tern Project last year which was also a record year so our good luck continues. However, we are under no illusions and records do not matter in June. We will see how the Little Terns are doing in August! Nevertheless it is great to see so many of them nesting here and with the good weather we hope this excellent start continues.

The good news does not stop there as our first Little Tern chicks of the year hatched today! K1, found on the 25th of May, had 2 chicks this morning. When we checked the nest the second chick had just hatched and it was unusual to see the egg shell still in the nest and yolk on the head of one of the chicks! K1 was laid earlier than the rest of the group so most off the hatching will take place later this month. There are a staggering 244 eggs on the beach. This makes the colony all the more attractive and vulnerable to predators. The colony is now a beacon to predators with so many birds and eggs and the density of nests is so high that any stray dogs (or members of the public!) have a much higher chance of crushing eggs if they enter the colony.

We started seeing some strange creatures drifting under the bridge into the lagoon a couple of days ago. We now have up to 40 Barrel Jellyfish washed up into the lagoon. Some of them are gigantic and can be up to 80 cm in diameter and weigh 35 kg! Check out this link to find out more - http://www.jellyfish.ie/irish_sea_jellyfish.asp#2. The good weather has also brought out the more colourful day flying moths such as the Hummingbird Hawk moth, the Six-Spot Burnet moth and the Cinnabar moth. The Oystercatcher chicks that hatched last week seem to be doing very well and starting to bulk up in size. We've also got another Oystercatcher pair nesting in the south end of the colony which gives us a total of 3 nests in close proximity. This gives the terns in the south end of the colony 6 hefty bodyguards.

The trials, tribulations and triumphs of a Little Tern Warden

* Before we update you on all the exciting news from the Little Tern Project I would like to remind everyone that there will be a joint Carlow and Wicklow Branch of BirdWatch Ireland outing to Kilcoole on Sunday the 15th of June. We will be meeting at the Kilcoole Railway Station carpark at 10:00am. This is always a great opportunity to meet some of the conservation team and get a guided tour of the Little Tern Colony!

It has been a strange week here in Kilcoole full of highs and lows. The nest explosion has continued and we're still finding more by the day. We have more than double the amount of the nests than the previous year! However, we were brought back to reality on Monday morning the 9th of June (the day the Earth stood still) after we discovered that 10 nests were depredated in the space of a couple of hours! 4 nests were completely destroyed and 6 were partially depredated, 4 of which were later abandoned. We did not see the culprit but based on the evidence it was almost certainly a corvid. It was most likely one of the usual suspects, Hooded Crows or Rooks, but we're not ruling out the Jackdaws, who have become ever bolder in entering the colony in search of food. It was hard to take at the time, especially as we were steamrolling our way to 100 nests! Luckily this attack has come early in the season, meaning that affected Little Tern pairs have a chance to relay, so all is not lost. For the moment the attack remains an isolated one but we will remain vigilant. The topography of the beach is more erratic than in previous years which leaves plenty of blindspots for predators to exploit and there is no predator out there as canny as a corvid.

Disturbance in general has been quite high this week with a number of unleashed dogs wreaking havoc on the foreshore and we recently discovered a nest, with the egg intact, covered in blood. A grim sight and proving to be a bit of a mystery. Before Monday morning we lost one nest to an unknown predator but we suspect it to be an Oystercatcher. Oystercatchers do not really look for Little Tern nests but, like most animals, they are opportunistic and will not tern down a free meal! We also lost one nest to the tides. We have a number of nests that are precariously placed on the foreshore that we are keeping a close eye on. The Spring tides are fast approaching but the forecast is looking good so fingers they can get through the next week.

The road to recovery has already begun. We have subsequently found  7 nests and we know there are more out there. We now have a staggering 91 active nests with a combined total of 216 eggs! In the knowledge that there are more nests to find and that there are 10 pairs that need to relay, we know that we have over a 100 breeding pairs in Kilcoole which is great news. We are also expecting the first Little Tern nest (K1) to hatch in the next couple of days. Our first Oystercatcher nest hatched yesterday and we now have 3 prehistoric looking chicks running around on the beach to join the Ringed Plover chicks!

There is always exciting wildlife to be found  in Kilcoole. The good weather has brought out the butterflies, damselflies and lizards but the highlight of the last couple of weeks has to be this stunning Osprey which briefly flew south past the colony!
