Bats, Insects and Climate Change

 
Say thanks to the small free-tailed bat
Who consumes both the earworm and gnat
But the climate is warming
Too soon they are swarming
And the crops in the fields will fall flat
 
 
The Scientific American has an article "Bats are migrating earlier, and it could wreck havoc on Farming" which relates to the way climate change is affecting the Mexican free-tailed bats that migrate to Bracken Cave, Texas, in vast numbers, and which eat many of the insects which are agricultural pests.
 
Bats are not so significant in the UK, and an article in a Devon newspaper, The Moorlander, this week, reminds me that my interest in bats dating back about 60 years. The Devon Greater Horseshoe Project is conducting a survey this summer using bat detectors to count bats as they hunt for insects. About 60 years ago I spent time actively recording and ringing hibernating Greater Horseshoe Bats in Devon - for the pioneer bat ringer, John Hooper, One of my activities involved checking some of the smaller caves and mines in the area between Buckfastleigh and Chudleigh. While I no longer live in Devon, I do visit occasionally and will be most interested to see the results of the survey.

In the past, coming from the abyss.
There emerged, on four legs, a small fish.
Then came ape, and then man,
Plastic pot, and tin can,
And then piles, and more piles of rubbish.

Captured by the Camera

A Winter View at College Lake, near Tring
Things have not gone as planned over the last few months and my top priority is to keep fit and relax - and what better place to do so than College Lake - and this year I will try and include some more relaxing "Captured by the Camera" shots - and forget about the horrors of Brexit and Trump.
