Unexpected visitors

There were two unusual visitors at the colony over the past few days.

The first was a Manx Shearwater. Generally only seen far offshore through our telescopes, this bird was caught during an overnight mist-netting session by Declan Manley. After taking and recording its body measurements, the Shearwater was released back into the night with a shiny new ring on its leg.

The second visitor was even more unexpected. Our warden Jerry was keeping an eye on things from the bird-hide when he heard a scratching on the roof above his head. Thinking it might be a small flock of the juvenile Starlings that landed on top, he leaned out the window only to find himself face to face with a Grey Squirrel. Moments later, the startled squirrel was racing away down the train tracks with an angry mob of Terns on its tail.

A squirrel is indeed an unusual sight in the colony, since there isn’t a tree for miles. He is unlikely to be of any threat to the Terns, but their intensely defensive behaviour probably scared him off for good. However, it is great to see the colony protecting their eggs and chicks so fiercely. We have over 70 chicks on the beach today and it is good to know they are so well guarded!

What a wonderful week we have been having down at the colony. After the exciting news last Friday that our first nest hatched two chicks, the fluffy-count has shot up. Today we have 54 little ternlets on the beach, and I daresay that number will be up again after this evening’s nest rounds. There are 117 active nests still out there with 240 potential hatches!

We have had all sorts of chicks. The first two that hatched are a week old now. They have moved away from Nest No.1 permanently and always appear in the same seaweed pile every morning. They’re huge, and gambol about after their parents with their tiny fuzzy wings outstretched for balance.

Younger chicks, such as those of Nest No.8, haven’t quite mastered the art of scampering during their first 24 hours on this earth. Master Nest No.8 gave me a right laugh this morning when he tried to climb out the sides of the nest scrape. On finally summiting the lip of the nest, he lost his balance, tipped over backwards and rolled all the way back down, finding himself with his little red legs and fuzzy white belly in the air before he was swept back under a protective grey wing.

We also had a most unusual sight when we reached Nest No.7 on last night’s nest rounds. Two of the three chicks are the usual sandy-and-speckled-black cuties, but the third is a snowy white albino tern with red eyes. Although the parents were happily brooding all three this morning, the albino is noticeably tinier and more helpless than his brothers. Only time will tell whether he is healthy enough to pull through his first days.

For all the other ternlets on the beach, their first days have been kind to them. The weather is dry and so warm that many chicks are lying out in the sun next to their parents instead of cozied up under them. We have put out old roofing slates as “chick-shelters” to provide cool shade on intensely sunny days as well as a refuge in wind and wet. While one parent broods, the other hunts and brings food back to the nest. He lands beside his brooding mate, enthusiastically brandishing a sandeel in his bill. He holds it with great hope next to one wing, waiting for a young one to poke a head out. Nothing. He hurries to the other wing and waves the sandeel around in delighted anticipation. Finally, one chick catches on to the situation and the brooding parent jumps up suddenly as all three chicks struggle out from under her and come greedily running. The first one to the finish line wolfs down the eel, and straight away the parent is soaring back out to sea for more.

More tales from the colony to come.

A Tale of Two Oystercatcher

Little Tern chicks are not the only new faces about the colony. Only a couple of days ago, the first of the colony’s two Oystercatcher nests hatched. There were two dark brown and fluffy chicks huddled among the rocks, giants compared to the tiny tern chicks, yet still no bigger than my fist. Evening was closing in fast, so after a quick photo, I left their dubious parents to come back to brood.

Although tiny, Oystercatcher hatchlings are far bigger than Little Tern chicks

The following morning, I combed through the vegetation with my telescope to see how the new arrivals were getting on. The two were still close to the nest, crouched low into the stones while the parents scrutinized me from afar. I expected that I would find them in the same area of beach for at least the next few days, while they were still so helpless and fluffy.

But how they proved me wrong!

I was in the middle of dinner when I got a call to say both chicks were on a mission of lemming-like proportions, heading away from the nest. Their destination was the lagoon, which offers a safe haven with plenty of food, so their parents were calling overhead to encourage them to these greener pastures. However, the beach and lagoon are separated by the ultimate dangers: the railway track and the pedestrian footpath. Joggers! Dogs!! Commuter-rail!!!

The young chicks' destination...with a dangerous interlude!

The wardens jumped into action. When I caught up with their flight, they had survived the perils of the footpath, but were struggling to get through the railway fence and onto the track. We rescued them both inside a hat and hatched a plan to convey them across the tracks to the lagoon side, while making sure their parents knew to follow.

The reckless attempt is intercepted

The Oystercatcher parents were quite alarmed to see their young traveling over the fence in an upturned hat, but they got the jist of what was happening, because once we had turned the chicks out from their makeshift habitat, the parents were quick to circle in. After a few minutes of baited breath, I watched the family reunite from a hiding place in the boulders.

Today, the chicks are happy out in the lagoon, still in roughly the same spot they were released. We wardens will be better prepared for such exploits when the second Oystercatcher nest hatches, and hopefully these two chicks will be joined by four more in a couple of weeks.

New life at Kilcoole

This week was a busy one at Kilcoole. Early in the week there was a large influx of adult terns into the colony, with max counts of over 250 individuals. This lead to great excitement amongst the wardens over this fresh potential for a large number of new nests. The large number of adults is also an advantage for the terns because they are better able to mob avian predators.

A substantial number of terns started to lay eggs and build scraps to the south of the protective predator fence. On Wednesday morning wardens were busy at work extending the fence future south as far as the breaches outlet to incorporate these new nests which would otherwise have been exposed to a number of mammalian predators.

By weeks end, the number of nests was up to 84, and included just over 200 eggs! Wardens continue to find new nests daily and this number is estimated to continue to grow well into next week.

Thursday afternoon saw the first cracks beginning to appear in the first nest that was discovered 21 days ago. Much to the warden’s delight, early Friday morning, there were two fluffy tern chicks freshly hatched in the nest. This nest was a very early layer and it is expected that no more eggs will hatch for another 3 or 4 days, and with a large bulk of the first batch of eggs hatching on the 19^th and 20^th of June.

Two nests of Ringed Plover also hatched on Friday morning, with 4 chicks each. Unlike the terns these Ringed Plover chicks run off the nest on their very long legs to hide in the shingle mere hours after hatching! As a species, Ringed Plovers are very promiscuous, and chicks learn to feed and take care of themselves very quickly. All that was seen of these little chicks was the broken bits of shell which they had escaped from earlier in the morning. The Little Terns, however, require a lot of parental care and rely on their parents for food right up until fledging. We will be seeing a lot of this around the colony soon as all our eggs begin to hatch!

Sunny Side Up in Kilcoole

The Terns are doing a fierce job making nests and laying eggs. This week has been a brilliant one for new nest discoveries! Tonight, we have a tally of 75 active Tern nests and 189 eggs on the beach, which we are, of course, delighted about. The expected arrival date for the first little ternlet is coming ever closer – I hope to meet my first chick of the 2015 season within two weeks.

Our remaining Ringed Plovers are very close to hatching. Several nests have slowly cracking eggs. Likewise, our first Oystercatcher eggs are cracking (ever so slowly), keeping us in great suspense! I regularly come across three of the four Ringed Plover chicks that hatched this week as they have stayed in the vicinity of their nesting area in front of the hide. The parents spend all day long searching for them among the stones, whistling and darting back and forth towards the chick’s calls. They find one, only to loose the other two and set off again. They try to sit and brood another, just to hear the call of the third and jump straight back up to find it, while the first scarpers into the grass again!

The good weather and sunshine looks set to continue for the time being. Hopefully the high pressure will keep the tide at bay and prevent a repeat of last week’s wash out. If the sunshine stays in Kilcoole, we may have another great rise in nest numbers by next week.

Ringed Ringed Plovers

We had a lovely evening when one of our Ringed Plover nests hatched four adorably fluffy little chicks. These four chicks were ringed with metal rings so that we can monitor their progress in the colony and perhaps see where they head off to as adults.

For you know I'd even try to turn the tide

Alas, after such a positive start to the season, our fortunes did not last.

The Terns and I survived the unruly wind and rain all day Monday (see how the wind took half of our Warden Flag - raised 24/7, because we are here 24/7!). The weather eased and calmed by sunset, but there were indicators that something was coming – Manx Shearwater were visible from the shore and a large pod of Common Dolphin passed very close, both telling of storms far out to sea. 

The wind took half our flag off!

 That night, the tide came in… and kept coming in further… and further … and further. The unusually high tide surge, probably pushed by a sea storm, obliterated our seaward fence and claimed many nests in the colony.When I rolled into bed on Monday night, we had a colony-count of 51 active nests and 136 eggs. On rolling back out Tuesday morning, we had 41 active nests and 108 eggs. Altogether, 10 nests were lost. It was a sad old morning surveying the damage from the bird-hide: many Little Terns were sitting on top of the fencing and seaweed that had buried their eggs.

On a happier note, 7 new nests were found after the tidal sweep. Thus, the Tern facts and figures are currently at: 48 active nests (out of a total of 62 nesting attempts) and 119 eggs. Not a bad way to be indeed! It is so early in the season that many Terns who lost their nests are likely to re-lay, and sure enough, many Terns were observed digging scrapes and sampling nest spots today.
