14th August: Events this weekend

Two events are taking place on Lindisfarne NNR this weekend:

Saturday 16th August, 11.30am - 1.30pm
Butterfly Walk

Join Reserve Warden Laura for a walk around Lindisfarne NNR to learn how to identify and record our spectacular butterfly species. This is also a great chance to see the rest of our amazing wildlife including the NNR's birds and flora along the way.
Booking is essential as places are limited.
Meet at the Window on Wild Lindisfarne, grid ref. NU129419

The Peacock butterfly, one of many you might see on our butterfly walk

Sunday 17th August, 1.30pm – 4.00pm
The Lost Buildings of Lindisfarne

Come along to Lindisfarne National Nature Reserve to see there's more than nature hidden in the dunes! Join local historian and volunteer John Woodhurst to explore some of the island's less well known historic sites and discover Lindisfarne's once thriving, but now mostly forgotten, industrial heritage.
Booking essential.
Meet at Holy Island Main Car Park - a car parking charge is applicable.
Grid ref: NU 126 423.

11th August: Shorebird season update

Mhairi, Northumberland Little Tern Project co-ordinator, has an update on what the shorebirds are up to now that the breeding season is over:

Shorebird Season – ups and ups but still more to do!

Well on the coast here we have had a brilliant breeding season for our shorebirds! New fences have meant that new areas have allowed ringed plovers to thrive where there was high disturbance from humans and dogs in the past. All along the Northumberland coast, we have also had good numbers of breeding terns, which have translated into a great year for fledglings.

So that’s it, 31st of July the fences come down, give ourselves and the birds a pat on the back - and relax knowing we have done our bit until April next year?

Well yes and no! The birds have finished the hard part having successfully negotiated high tides, threat of being eaten and the odd stray balloon which looks surprisingly like a bird of prey from the ground. However, the chicks are facing new threats now they have turned into fledglings (a word for those in the know to describe those chicks which are taking their wobbly, haphazard first flights), now having to flop and flap their way down to the water’s edge to follow their parents. They then hang around the shore waiting to be fed until the penny drops and they attempt to feed themselves (again rather haphazardly). All this time on the beach opens them up to new challenges. They are about to start their first ever migration to their wintering grounds. There is no dress rehearsal - once they leave the safety of Northumberland’s beaches they have to fly thousands of miles to find favourable areas for them to winter. Take the Little Tern, just one of the birds you will find on our beaches: the furthest a Little Tern from the UK has been found to migrate is Guinea-Bissau. A quick google search tells me Guinea Bissau is in West Africa on the sticky out bit - a massive 4000 miles.

The distance and the timing of this migration means that our beaches play one last role in the lives of our young terns before we see them in two years time when they return. And we can all help – if you see large roosts of terns or other birds on the beach keep dogs under control try to avoid walking through them and most of all enjoy watching this spectacle. Help by giving them the time they need to take some food from our North Sea larder, gain strength and get ready for their epic journey.

I’ll be giving an update from the breeding season when we get all our reports together and also give you an idea of how the EU Life project has helped nationally.

9th August: Porpoise found on beach

Along with the jellyfish we posted photos of earlier in the week, a dead porpoise was also washed up onto the beach. It looked to have died from a large wound to its underside. One of our volunteers discovered it and took a photograph so we could try to find out what happened.

We contacted the Cetacean Strandings Project at the Natural History Museum who replied that it was not possible to say for sure what caused the wound, however one possibility is a Greenland shark which has been recorded in the North Sea. The Greenland shark is a scavenger and has been reported to feed on porpoise bodies, removing large chunks, and the porpoise wound does suggest one large bite. The photo has been passed on to experts who will hopefully give us a definitive answer. The further damage looks to have been done by other scavengers, possibly seals.

It can be distressing to see dead animals washed up on the shore, but reporting them provides important information which helps us understand more about these creatures. If you find a dead animal such as seals or cetaceans washed up on the shores of the Reserve, please call the Reserve base on 01289 381470 so we can report it to the relevant organisations. If you find a live animal that is wounded or looks to be in distress, it is crucial that you call us so we can try to rescue the animal.

5th August: Pirri-pirri bur work update

Since our last update on Pirri-pirri bur removal works we have removed burs from more of the main paths on the NNR and trialled a new machine.

First we used a grasscutter on the main paths to cut the Pirri seed heads and leaves, then used the new machine which is like a giant vacuum to suck up the burs loosened by the cutter.

The combination of cutting the Pirri-pirri bur then using the vacuum has worked very well, meaning we can clear more paths of the burs which prevent them being spread to other sites on shoes, clothing and animal fur.

31st July: Jellyfish washed up on the shore

A large number of jellyfish were washed up on Lindisfarne NNR recently after some high tides pushed them up onto the beaches.

Blue jellyfish (Cyanea lamarckii): the vibrant blue colour of this jellyfish is where it gets its name, but sometimes they can be pure white! It's tentacles can grow up to 1 metre in length but its body is normally around 15 cm in diameter. This is a widespread visitor to Britain's coasts.

Moon jellyfish (Aurelia aurita): these distinctive jellyfish are commonly found in estuaries and harbours as well as on the shore. The moon jellyfish is easily identified by its 4 round gonads seen through the translucent body.

Lion's mane jellyfish (Cyanea capillata): a large jellyfish, usually red or brown in colour. You may be surprised to learn that this is one of the largest animals in the world - it's body can reach over 2 metres in diameter with tentacles up to 150 ft long - much longer than a blue whale!

If you find jellyfish on the shore, be careful not to touch them as they may still sting even when dead.

30th July: Peak count of Little Egrets on Lindisfarne NNR

At 8.00am this morning, 21 Little Egrets were spotted just south of the Causeway next to the mainland. This is the highest ever count of Little Egrets on Lindisfarne NNR - Reserve staff headed out to take some fantastic photographs of the group:

If you are visiting Holy Island today, keep a look out for this group of elegant Little Egrets to your right as you approach the Causeway. You can park in Beal car park and view the birds from here - remember not to get too close to them to prevent disturbance.

29th June: Shorebird Celebration - Tomorrow

It's nearing the end of the breeding season and it has been a busy, challenging few months for shorebirds on the Reserve and further afield. Reserve staff and volunteers think it is a great time to celebrate the birds of Lindisfarne NNR for their hard work brooding nests and rearing chicks!

Come to the Window on Wild Lindisfarne between 10.00am and 1.00pm on Wednesday 30th July to make your own craft shorebirds and chicks, and enjoy learning about these amazing birds and the incredible journeys they make on migration.

Enjoy making your own shorebirds, learning about migration, colouring in and more at our fun event tomorrow
