My 100 Nest Box Challenge

Blog 18 (part 1)


Why am I doing this?

During 2017 I visited many fantastic wildlife reserves across the UK as well as taking part in the BTO Bird Camp in May.  Inspired by my experiences, I decided I wanted to give something back to some of the charities that do such great conservation work. So ……. the 100 Nest Box Challenge was born!



Using my pocket money and with a bit of help from my dad to collect the materials I’m building 100 nest boxes from scratch – myself.  My plan is to have made and sold (for a minimum £10 donation) all 100 nest boxes in time for National Nest Box Week (14 – 21 February).  All money raised from selling the boxes will be split evenly between the following 3 charities:

I hope that many of the nest boxes I make will be bought by people in my local area  encouraging them to take a greater interest in supporting wildlife.  I’m particularly keen to get more children taking an interest in wildlife issues and will be promoting my project to local schools.

Haiths even sent me 1 box to contribute.; this will be donated to my local park. Thanks!!!!

How Do I Order a Box?

If you are interested in ordering a box please get in touch with me via my ‘Contacts‘ page. I can send boxes to anywhere in the Glasgow area without delivery charge. I can also send boxes outwith the Glasgow area but still within mainland Britain for a delivery charge which will depend on the number of boxes being ordered.  I can confirm postage costs if you specify the delivery postcode and number of boxes required in your enquiry.  Payment by cheque would be preferred.

You can see how much money has been raised from the project so far by looking at the totalizer on my home page.

What if I don’t want a nest box but would like to make a donation?

Alternatively, if you would prefer to make a donation I have set up a crowd funding page at

Please note that any money donated through this route will only be used to buy materials to make nest boxes & other wildlife homes/habitats which will be given free of charge to local schools, community organisations and parks. Only money raised from actual nest box sales will go to the three charities detailed above. 

The totalizer on my webpage only shows the amount raised from nest box sales. If you want to see how much money has been donated go to the just giving page linked above.
