Batty about bats in #Manchester – echolocation, biodiversity and climate change

MCFly volunteer Sarah Irving learns about bats in one of Manchester’s loveliest parks.

It’s no shock when an outdoor event in Manchester gets rained off. But at least we got to come face-to-face with a pipistrelle,  Britain’s commonest bat;  in the hands of a gloved expert it looked like two inches of quivering, furry energy bursting to take off around the room.

This was the high point of a talk from Simon, an ecologist and member of the South Lancashire Bat Group  hosted by Friends of Platt Fields in Rusholme. We may not have got the promised walk around Platt Fields lake with bat-detecting equipment, since bats don’t come out in the rain (even Mancunian bats). But we did hear how the Daubenton’s,  another bat species, feeds on small insects on the surface of water by scooping them up with its big furry feet.  (see picture!)

Other bat facts:

  • individuals from some of the 17 or so British bat species live up to 30 years;
  • bat hearts beat up to 300 times a minute when flying but drop to 10 beats a minute while hibernating;
  • scientists have synthesised an anti-coagulant called ‘draculin’ from the saliva of Central American vampire bats, and
  • vampire bats show one of the rare examples of co-operation in the animal world, with some individuals regurgitating food (yes, blood) for fellow (but unrelated) colony members.

Then there’s echolocation  as a means of catching your dinner, which is just mind-bending in its incredibleness. Really.

And you know how all the men in a room wince and cross their legs when testicular injuries are mentioned? The female equivalent is watching all the women in a room react to the information that baby bats are a third of their mother’s weight when born – roughly analogous to a women giving birth to a 3-stone infant.

Ouch.

There was, of course, a serious message to the evening. Most British bat species are in decline, falling prey to habitat destruction (especially the loss of most of the country’s ancient woodland) and reduction in food supplies due to wetland drainage and insecticide use. As long-lived, slow-breeding species, they may also be especially impacted by the habitat changes that climate change will bring about. In fact, a major report published only yesterday says that bats around the world have been seriously affected by climate change, and the situation is expected to get worse.

As well as the loss of biodiversity this represents, falling bat numbers around the world could impact on other species, with bats playing important roles in pollinating some plants (including bananas) and spreading seeds.

In the short term, there is information on how to make a bat-friendly garden or other local environment on the Bat Conservation Trust website.

    fantastic, went on a bat walk tonight very inspiring and what a great bunch the South Lancs bat group are, Steven our guide was very passionate and knew his stuff, think he said the oldest bat recorded was 42 not bad for a little fella eh? great article btw, these little creatures are so misunderstood they do not spread disease, dont bite or attack you and dont suck your blood whilst you sleep! or cause rabies! they do however eat the nasty midges that bite you! They are declining due to habitat loss and people replacing their wooden barge boards and soffitts in their rooves (the eaves basically) with upvc plastic ones that tend to seal up gaps so that bats cannot roost in loftspace (which is harmless) so we need to all do our bit…..education is crucial for the survival of these increasingly rare mammals, bat walks for kids should be encouraged more on school weekend field camping trips maybe……and bat box construction as school projects the bat conservation trust has details on how to make the ideal bat nest box called the “Kent” which is the best design for them apparently. Sarah has the link on her article above for more details.

    No probs Mark, you seem to have the makings of Manchesters first Green MP perhaps? I like your articles very much, insightful and informative, some great research and debate, well done. I applaud your efforts. I will send any useful links I have onto you. Cheers.
