  • Commas cause quite a commotion...

    Thanks to some careful management, the meres are getting shallower. This is proving brilliant for spotting some extra wildlife that might otherwise be more difficult to see at this time of year.

    At Lilian’s hide, several water rails are pottering about with their young closeby. Looking at these birds head-on they look distinctly two-dimensional: their flat shape allows them to manoeuvre easily through the reeds and stay hidden from predators. Water rails are secretive birds and can usually be seen better in winter when they are forced to come out to the pools edges to find food.

    Down at Grisedale hide, snipe can be more easily seen at the edges of the pool, weaving in and out of the reeds. Grey herons and mute swans use Lilian's and Grisedale hides as their bases - the cygnets may almost be reaching adult size now, but they still follow their parents closely through the dykes and waterways.

    Over the weekend, butterflies and dragonflies have been out enjoying the sunshine with brown hawkers fighting each other in the air to defend their fiercely guarded territories. This beautiful comma butterfly was also seen on site. Its frilled edges make its flight pattern look slightly erratic as they flit between the ferns. However this interesting shape also gives it the appearance of a withered leaf when its wings are folded, providing excellent camouflage.

    You’ll be pleased to hear our three great white egrets are still about. One can be seen regularly strutting across Lilian’s pool throughout the day, and another is frequently seen from Public and Lower hides amongst a group of little egrets.

    But get down soon or you might miss them!

  • Beautiful butterflies

    With all of this gorgeous weather we have been having, butterflies have been flitting around among the flowers in our garden and out on the reserve, so I thought they would make a nice subject for one of our 50th anniversary blogs.

    So just how many different types of butterfly are there here then?

    There are 59 different types of butterfly in the UK. Leighton Moss is home to a fantastic range of them during the summer months, with 35 different species recorded to date. Butterflies have been a feature of the reserve for its whole 50 year history. More common ones such as red admirals and small tortoiseshells add dashes of colour along the edges of the paths at this time of year, when there is an abundance of wildflowers in bloom. Up on Warton Crag you can spot much rarer butterflies such as the high brown fritillary.

    In the spring and summer, our Wardens carry our surveys every week to see how butterfly numbers are doing. Due to differing life cycles, you get peaks of when you see more of some species than others at certain times. For example, brimstones are often the first ones in the year to appear, and have been known as early as February if the weather is mild, whereas pearl bordered fritillaries only tend to start being seen in June.

    Unfortunately, over the last 50 years butterflies have suffered a rough time in the UK. The State of Nature Report launched in May last year showed that 72% of butterfly species have declined, including a 24% decline in the more common garden butterflies such as peacocks. This is largely due to the loss of places where they live.

    You can really help butterflies by planting flowers to provide feeding areas for them in your garden or community.

You can also assist them by taking part in the Big Butterfly Count, which is running until 10 August - click here for details.

  • Sedges on the edges

    You may have noticed that I missed doing a 50th anniversary blog last week - apologies for this, but it does mean you will be treated to two this week to catch up!

    A month ago, I chose a reedbed favourite at this time of year - reed warblers so I thought this week would be good to look at their cousin, the sedge warbler.

    Now they won't be around for too much longer (although this glorious weather might mean they hang about a bit), as sedge warblers are migrants. They arrive here in mid-April from Africa in order to breed., and will have 4-5 young in a brood (sometimes they will have a second brood).

    As you walk through the reserve, you can't fail to hear one. Now they can sound remarkably similar to reed warblers, but whereas the reed warbler remains fairly level in their song, the sedge warbler gives itself away by sticking in some fluty bits. If you are listening out for them along the trails then you sometimes have to wait a moment for the sedge warbler to add in its fancy notes to establish which one of the two you are hearing. Sedge warblers often differ in their location within the reedbed too. It isn't a hard and fast rule, but generally sedges (sedge warblers) are on the edges, and reeds (reed warblers) are within the reeds. Sedge warblers will often sit up high on top of the reeds or willow to sing, whereas reed warblers tend to skulk low down a little more.

    Once you do catch sight of them, sedge warblers do differ in their appearance from reed warblers. The most distinctive difference being that sedge warblers have a beautiful white eyestripe. I always remember it as 'sedges have a stripe' so the two 'S' sounds go together.

    Sedge warblers have always been present here from the beginning. They breed in reedbeds but are also happy to raise their young in a variety of other place too such as marshes, riverside scrub and in trees or bushes alongside wet ditches. They have also been known to nest in the edges of crop fields! Sedge Warblers eat a variety of food including aphids, mayflies, grasshoppers, lacewings, moths,  beetles and flies. They also feed on berries such as elderberries in autumn.

    If you've not heard or seen one before, come along in this fine weather before they head off south!
