It's that time of year when every day sees new migrants moving through on their way to their summer homes, and this week there's been plenty of variety out on the reserve. We had a male cuckoo at the far end of the reserve on 6 May, a whinchat also on 6 May, yellow wagtails on most days and up to 8 wheatears on the Estuary Track. Waders have also been moving through, heading up to their northern breeding grounds - small parties of whimbrel are seen daily out on the estuary, along with groups of dunlin, and we've spotted both ruff and grey plover on the Deep Lagoon. High tide has often brought small numbers of sandwich terns into the estuary, following the fish which they feed on - their rasping cries are unmistakeable as you walk along the Estuary Path, so keep your eyes and ears peeled for them! Two Mediterranean gulls also briefly visited us on 7 May, and on 12 May we were treated to two red kites sailing over the reserve, heading south down the valley.

The most spectacular sight this week was on 10 May, when hundreds of swallows and martins were seen on the ground in front of the Carneddau Hide. It was a cold, wet and windy day, so presumably they had recently arrived on migration and were exhausted from struggling against the weather. There seems to be plenty of food for them on the lagoons just now, as we've had a big hatching of non-biting midges - you can see them caught in the spider's webs on the windows!

Our hapless pair of great crested grebes are suffering their usual trials and tribulations - having built the nest in a very exposed situation right in the middle of the Deep Lagoon, they were washed out within a few days. Undeterred, they decided to build again in exactly the same place, and again the nest disappeared. Thankfully they hadn't yet laid any eggs either time. They then appeared to have an attack of good sense and started building closer to the shore by the causeway, but that evening when I went along to see what they were up to, they were busy building back in the first location again, and a big fat terrapin was sitting in the middle of the sensible nest! The terrapin has been here for several years, presumably dumped when it outgrew its tank, and is always a surprise when you first spot it, as not quite what you would expect to see here.

On Wednesday 16 May, we're going to be having a special evening when we open up the Coffee Shop after the usual Summer Evening Stroll. If you fancy coming along for a cup of coffee and cake sitting by the Shallow Lagoon as the sun sets, then come along for the walk  - no need to book, just meet at the Estuary Gate at 7pm, and the walk is free!

This is a bit of a catch-up, as we've had a busy few weeks. Remember that you can keep up-to-date with our nature news on Twitter or Facebook in between our blog posts. This brilliant photo of a willow warbler was our April Photostream Conwy Picture of the Month, and will be used in our social media throughout May.

Despite getting their nest washed out by last weekend's rain and winds, the pair of great crested grebes will not be defeated and have built a new nest, that looks a bit more substantial. Fingers crossed for better weather. We're hoping that some better conditions will also help the first lapwing chicks that hatched on Thursday.

There are still a couple of pairs of little ringed plovers around the reserve, but neither seems to have settled yet.  Waders have been a bit slow coming through, but a few whimbrels and dunlins have been here the last few mornings, along with bar-tailed and black-tailed godwits and a smart summer-plumage knot.

We've had quite a good number of Sandwich terns in the estuary this spring, including six on Thursday 3rd, perhaps pushed in to shelter by the northerly winds.  A whinchat was a nice surprise this morning, feeding alongside four wheatears on the saltmarsh.  A few yellow wagtails have been among pied and white wagtails on the estuary this week, but the wagtail passage has diminished in the last few days.  A grasshopper warbler was on the Ganol Trail on several dates, most recently on Wednesday (2nd).  The cowslips are still looking spectacular around the coffee shop, but get here in the next few days to see 'em, as they'll soon be over.

The swallows, swifts and martins have been a spectacle over the last few weeks, feeding low over the lagoons during poor weather, and around your head over the estuary track if it got a little warmer.  Other highlights during late April include six white storks over Llandudno on Monday 23rd (but seen from the reserve by standing on a picnic table!), ring ouzel in the paddocks on Sunday 15th and redstarts on Sunday 15th and Monday 30th.

Not all our visitors are welcome
The first visitors to the reserve on Friday were greeted by the sight of the Benarth Hide with part of its roof ripped off and the guttering wrecked: we'd been visited by some undesirables (that's not the culprits in the picture, even though they might look a bit suspect...).  Thanks to our alert visitors and social media, we knew about this before we'd even arrived on site!  Two of our brilliant outdoor volunteers, Dave and Phil, came in this morning and did some temporary repairs, at least to ensure that it's watertight over the next few weeks, but ultimately we'll have to replace the whole roof, at a cost of hundreds of pounds.  That's hundreds of pounds raised by volunteers, donated by visitors and members, which we can't spend on something else.  What a shame!

The man from planning, he say "yeah!"
On a more positive note, we were delighted to receive confirmation last week that Conwy County Borough Council has approved our plans to create new outdoor visitor facilities, the centrepiece of which is Y Maes.  We've also appointed a Project Officer, to organise the programme. Laura Kudelska starts here on 21 May, and we look forward to her helping us transform the area between the Visitor Centre and the Coffee Shop.

Get out and enjoy the reserve
The Summer Evening Strolls have restarted for the summer, every Wednesday evening at 7 pm (you don't need to book). The reserve is a brilliant place to spend a couple of hours on a summer's evening.  And we've just posted our June events online, so see if there's something that grabs you. 

PS. We still have a few places left on our Birds for Beginners course on Sunday 27 May.

Our big news this week is that at least two, and perhaps three, little ringed plovers are on the Deep Lagoon, and by their behaviour this morning, they're up for nesting here again.  The exposed mud in front of Benarth or Carneddau Hide is the best place to look.  This little wader, with its bright yellow eye ring, is a visitor from west Africa, so will they stay to breed?  A few black-tailed godwits and dunlins have been among the curlews and redshanks roosting at high tide.

Other migrants are trickling through, including 30 white wagtails with a couple of wheatears on the estuary this morning, and more willow warblers and blackcaps singing as the week progressed.  A whitethroat was reported on Thursday, and we had another osprey sighting on Easter Monday.  The flocks of sand martins and swallows are getting larger, with a few more house martins among them.  Some of the lapwings have settled down to nest, and we've seen robins and song thrushes carrying food this week.

The cool weather is making it hard-going for insects, but a few speckled woods have been flying on the sunny days.  Let's hope we have a few more of them this week!

We still have places on next weekend's Birds for Beginners event, if you know someone who might be interested.

It's only a week since we were writing about glorious weather, but the northerly wind and rain this week have slowed summer migrants, and kept a few wintering birds at the reserve.  The highlight has been another osprey this morning, hovering right above the coffee shop.  There are more sand martins feeding over the lagoons than last week, and a handful of swallows have been seen each day.  Our first house martin of the year was spotted on Monday (2nd).  One or two willow warblers have been heard each day, and blackcap has been singing since Tuesday.  Wheatears were seen on Monday, but these have been surprisingly scarce so far this spring.

On the water, our pair of great crested grebes are still here, displaying but showing no signs of nest-building, though a couple of pairs of Canada geese are already on eggs and one of two of the lapwings are bottom-shuffling, making scrapes that might become nests.  Shovelers and pochards have both been seen, and a few black-tailed godwits remained through the week.  Many of the curlews and redshanks have already left for their breeding areas, but a large flock of oystercatchers remains.  A first-winter Mediterranean gull was seen here on Monday and Tuesday. 

It's not been a great week for butterflies, but the stoats have been reported occasionally and it's worth looking in the pond to see if you can spot a newt - there are two species, palmate and smooth in there.  And for a splash of spring colour, the cowslips outside the coffee shop are still looking impressive and the dog violets on the estuary provide a purple patch for those on a longer walk.

Finally, a quick plug for a couple of events that are booking up.  The Birds for Beginners on Sunday 29 April is the first of three over the spring and early summer, while Wake Up with the Dawn Chorus on Monday 7 May is always a popular event, perhaps because it includes breakfast.

The week's glorious weather brought more early migrants, with the first willow warbler reported on Wednesday (28th) and the first osprey of the season mobbed by gulls as it flew north on Friday (30th).  Wheatears have been on several days this week, and the sand martin flocks are getting larger in size.  Butterflies spotted this week include speckled wood, small white, comma, peacock and small tortoiseshell.  A goldcrest singing in the car park on Friday was unusual for here; will it find a mate and nest?  If you're visiting this week, look out for the superb display of cowslips flowering near the coffee shop.

Our pair of great crested grebes have re-appeared this week, and we still have two little grebes here, so are hoping that both of these will stay for the spring.  A count of 26 little egrets was high for springtime, so will we see an increase in the nesting population across the river in Benarth Woods? Certainly there are plenty of grey herons on nest platforms.

The pick of the week's birding were two Iceland gulls, an adult and first-winter found by Rob late on Monday afternoon.  He managed to get a photo of one of the birds - a rarity here.

It's still early for passage waders but a flock of 10 black-tailed godwits that dropped in on Saturday were welcome.  The flock of tufted ducks is getting quite large for spring, with 25 birds yesterday (31st).  A kestrel was a last taste of winter on Friday, and a red kite was seen by several visitors on Wednesday, while a couple of redpolls were heard flying over later in the week.
