A stunning morning – it was tempting to say “Spring morning” because it was such a lovely day and there were lots of birds singing and calling.
Five of us gathered to help Steve Joul complete the surveying and cleaning of the FOAW nest boxes.
…And just when you think that you have seen it all after nine years of surveying nest boxes, you discover something new! – but more of that later.
Four of us met in Buckstone Road and drove the equipment down to the Slabbering Baby, and then two more Friends arrived as we were unloading our vehicles. We started by surveying the nest box by the Slabbering Baby, and then headed up the Meanwood Valley Trail in the direction of Stairfoot Lane to survey the nest boxes we did not manage to reach last week.
We then headed back to the Slabbering Baby and down the Meanwood Valley Trail to the Seven Arches.
As in previous years, most of the nest boxes were utilised last year. We found two nuthatch nests this morning – one in a wooden box, and one in one of our wood crete boxes. Interestingly, whereas the nuthatches had plastered up all the gaps in the wooden box, they had not bothered to do this with the wood crete box. With the nuthatch nest which we found last week, that makes three nuthatch nests last breeding season. We could hear nuthatches calling today.
The nest boxes had the usual range of critters in them: spiders, woodlice, the odd slug and ladybird, and lots of moth larvae.
We had one rather gothic find in we put up a box which was intended to be for tree creepers, but whose entrance hole is far too big. Inside this box we found the mummified remains of a squirrel!
However, the find of the day was when we opened a tit box to find a beautiful specimen of a noctule bat hibernating there. The bat was wedged up against the lid of the box and we immediately closed the nest box as carefully as possible. This was the first time that we have found a bat in a nest box in nine years of surveying them.
The noctule is the UK’s largest bat – it is 3.7 to 4.8 cm long and has a wingspan of 32-40 cm (that is up to 1’4″ in old money!). It roosts in trees and can be seen flying over the canopy in search of insect prey from April to October.
We completed our survey of the nest boxes at about 2.30 pm. Tired and hungry, but exhilarated by a fantastic day, we retired for our lunch!
