Radipole Lake

  • Dip into Radipole Lake...

    Well not literally but its amazing what families are turning up at our pond dipping platform this sunny summer. The ponds are simply heaving with wildlife and as well as the aptly named water boatman comically scooting around, the slow but beautifully formed pond snails who are great at cleaning up the algae and diving beetles with their amazing breathing bubble that they clutch to them, absorbing the air through their body. They have also been finding the super fantastic water scorpions and water stick insects, no prizes for guessing what they look like! These are ambush predators at their best. They have the equivalent of snorkels up their bottom which they stick out of the water allowing them to breathe and stay hiding in one place under water, looking out for prey. How cool is that! This year people have been finding common newt tadpoles with outrageous frilly feelers at the sides of their head as well as lots of stickleback fish and dragonfly and damselfly nymphs. Its a truly remarkable world down there so why not come over and get dipping and see what you can discover. Pond dipping is available 7 days a week from 10 am-4 pm.

    The marsh harrier story continues with we think 6 young fledged and on the wing from the 2 harrier nests (let us know if you have seen more together!) at Radipole Lake and Lodmoor, which is a fantastic result. Lodmoor as ever has been attracting the unusual with 3 great white egrets and a hoopoe during last week. The weather may still be sultry during the day but get out early morning and it feels like autumn is on the way and certainly the autumn migration is well under way at Lodmoor with wading birds like 3 types of sandpiper; green, common and wood, black-tailed godwits, dunlin, lapwing and redshank all busily feeding. Now’s the time to get to know your waders or just appreciate the shear beauty and elegance of these birds.

  • Little terns back from the brink!

    Morgan Vaughan and his fantastic team of staff and volunteers have been saving a species right here on our doorstep on Chesil Beach. This year 33 pairs of little tern have nested on Chesil Beach and produced 77 eggs. Hard to believe that just a few years ago the colony here was close to collapse with just a handful of birds hanging on. Its been a fantastic effort guarding the nest site night and day from disturbance by animals and people and now that the chicks have started hatching from birds of prey and other mammals.


    Here is Morgan’s story:

    It’s all going very well for the little terns, the weather is being incredibly kind to the terns and plenty of fish are coming in to fill the chicks. A majority of the fishing is happening out in Lyme bay. This was causing the chicks to gravitate up the bank towards the hide, affording volunteers, staff and members of the public wonderful views of the chicks which seem to be growing before our very eyes.

    At the start of the season around 80 coconut matting baskets filled with sand were placed out on the little tern nesting site and the majority of the birds chose these to nest on giving the eggs greater protection and warmth than the cold shingle.

    We have unfortunately started to have interest from a male kestrel at the colony so the excellent wardening team of volunteers and staff have increased their efforts in keeping him at bay and will hopefully prevent the kestrel from having lunch at our section of the beach.

    We have also deployed shelters for the chicks which they have been using to get out of the heat of the sun –  keeping them out of sight from hungry kestrels too.

     More excitement came in the form of the oyster catchers hatching – This will hopefully cause their parents to be even more aggressive to potential predators and help the little terns protect their young.

    68 little tern eggs have hatched in total this year – The last 2 hatching at the start of July.

    We now have at least 50 fledglings on the foreshore – A phenomenal success for Chesil beach little terns and testament to the dedication of wardens and volunteers involved in protecting the birds through proactive wardening efforts.

    Huge thank yous must also go to funders and partners: EU Interreg PANACHE project, Natural England, Crown Estate, Portland Court Leet, Dorset Wildlife Trust and the Chesil and Fleet Nature Reserve who without their support this would not have been possible.





  • Marsh Harrier 1 Magpie 0

    The marsh harriers have given us a scare recently after the male seemed to disappear for a couple of days, this was worrying as he should be bringing food in to the chicks or food passing to the female. Shirking his parental responsibilities surely not! Thankfully just as we were tweeting about it he returned and since then the first of the young marsh harriers have fledged from Lodmoor with 3 now testing out their wings over the reserve, very exciting!

    Some of our volunteers based up at north hide were treated to some very unusual hunting behaviour from the female marsh harrier at Radipole Lake who was seen flying into the top of a tree and coming out clutching a magpie. Behaviour more suited to sparrowhawks than marsh harriers!

    Excitingly a bittern has also been spotted flying close to the Discovery Centre at Radipole Lake, a rare occurance in June, all encouraging signs for this bird at our Weymouth nature reserves.

    The skies are full of activity and colour at the moment with lots of dragonflies and butterflies on the wing and newly emerged moths; scarlet tiger and burnet. At Lodmoor a grass snake was seen swimming up the channel.

    One lucky chap who kindly donated to the Chesil Beach Little Tern Project in return for a guided tour of Radipole Lake to see bearded tit was rewarded with great views of them and the masses of young about at the moment and walking back from the hide an otter was spotted along the River Wey too! Check out the fantastic pictures below.
