Guy Belcher from Cambridge City Council and ‘a few volunteers’ got together on Monday 27th January and installed 22-24 boxes in the belt of trees that borders the industrial estate.
These are German brand Schwegler nest boxes made of ‘woodcrete’ a natural product made from 75% wood and 25% ‘natural additives’ to allow air permeability. There are over 8.5 million Schwegler woodcrete nest boxes installed in Europe, US, Canada.
We helped put up a mix of boxes: larger holes for great/blue/coal/crested tits, as well as sparrows and bats. Boxes with smaller holes for marsh/blue/coal tits and possibly wrens.
Lisa, one of the FoSC volunteers says, “It was quite nice that as soon as a box went up, a great tit took up residence immediately. Also, bat boxes are placed to catch the sun, and I like the kind of ‘semi-detached’ situation with the two boxes next to each other.”
During his time at the University in 1665, Isaac Newton visited the Stourbridge Fair and is known to have bought a copy of Euclid's Elements which he used to teach himself mathematics. He is also believed to have acquired optical instruments including a pair of prisms - which he used to demonstrate that white light could be split in to the colors of the spectrum.
