We have an area on our property (of approximately 2000 sq metres) that we are steadily converting into native bush. Thankfully, we already have a good coverage of canopy trees that are of a height of around the 40 foot (plus) mark, and are now concentrating on introducing a sub-canopy layer of Five Fingers, Lancewood, and such like. We already have Tuis, Bellbirds, Moreporks visting us, but I would like to attract smaller native birds to live "in" the bush area that we are establishing.
I would like to introduce a good number of nesting boxes in this bush area, and are about to start building them myself. Can anyone please give me some guidance as to the size of the hole I should be drilling as the entrance hole for birds to go in and out through, to suit various native birds that may use these boxes.
Can you please indicate "what" native birds may use such boxes, and the corresponding hole diameter that I should be using to attract the given bird. Thank you.
Thank you for your help with this project.
P.S. We live at an altitude of around 500 metres above sea level, inland from Napier towards the Tararua Ranges.
