Building for birds – RSPB Leighton Moss

Reed beds at Leighton Moss

The RSPB reserve at Leighton Moss is the largest area of reed beds in the north west. I lived in Carnforth until 2012, and so it was right on my doorstep. As members get in free, I’d often have a wander in just to see if there was anything interesting to be seen and sometimes have tea and a scone in the tea shop. My main memories were of hides that were getting a bit worse for wear, and where you had to make sure you hooked up the windows properly otherwise you risked getting whacked on the top of the head while peering through your binoculars.

Bridge to nowhere (1)

When I first started coming to the Lake District, several decades ago, the road to the southern lakes and beyond was a narrow road, only just wide enough for one lane each way. Then pressure of traffic led to parts of it being widened and some bits becoming dual carriageways. One of these bypassed the pretty village of Lindale, but then the road became narrow again as it wound through Low Newton and High Newton. A few years before I bought Limestone Cottage in Levens, the dual carriageway was extended by building the High and Low Newton Bypass. This has speeded up the journey considerably (until you get to the next narrow bit), but can’t have done much for the passing trade in the pub in High Newton.

Anyway, the reason for this rambling is that there is this ‘bridge to nowhere’ over part of this new bypass. This puzzled me for some time.

Bat bridge

It is, apparently, a ‘bat bridge’. It is thought that bats navigate around their patch in the dark using their sonar to follow hedgerows or walls. Bats are reluctant to cross open spaces, due to the risk of predators, so removing linear features such as hedges and walls can restrict their commuting routes. When they do cross open areas they tend to do so low down – at vehicle height, with the inevitable fatal consequences.

Bat bridges like the one above are an attempt to mitigate these problems by providing a higher-level structure that the bats can detect and, hopefully, follow to cross the road. However in the years since structures like this have been built in various places in the UK, there is little evidence that they work – bats still cross open spaces lower down.

There is more on bat bridges here.

Ospreys and dragonflies – Foulshaw Moss

Foulshaw Moss is a few miles from the cottage at Levens, on the southern edge of the Lake District. Part of the area is owned by the Cumbria Wildlife Trust.

I’d read that there were ospreys nesting there, so I thought it was time for a visit. I saw the osprey’s nest, and with the aid of a ‘scope provided by one of the volunteers on site I might have seen the head of one of the ospreys… but what I really enjoyed was the discovery of a totally different landscape.

But first, the ospreys…

The nest is in the tree in the middle distance.
