You may be forgiven for wondering “where did birds nest before humans started supplying nest boxes?” Sadly chainsaw-wielding humans are increasingly likely to remove dead or decaying trees before they become choice homes for hole-nesting species, hence the importance of supplying alternative sites. Graham Bell explains all in a helpful article entitled THENEEDFORBIRDNEST. If you feel inspired to build a nest box yourself, Philip Hanmer has kindly supplied several designs in the article below…
NEST BOXES: We are indebted to one of our members and Barn Owl expert Philip Hanmer for the attached instructions relating to the building and siting of nest boxes. Links to his nestbox designs are embedded in the text of this page- see below. BARN OWL RESULTS 2017 of monitoring Barn Owls in the county is recommended and a fascinating read.
1)BARN OWL:Best location is an ‘open’ agricultural type building.
Second best is to locate in a tree with a good open view out; not inside a wood as you would for tawny owls. Philip’s latest design for a BarnOwl Box (click on link), and the associated cutting layout from two sheets of plywood can be accessed here. Cutting Layout
Don’t put boxes on poles in the middle of fields; they have lots of problems associated with them.
A height of not much more than 3m is best. A box can sit in a fork of a tree with one or two bearer beams of wood each side to make it level. Best wood for this is the stuff that has been dipped in preservative. The box itself should be painted on the outside with wildlife friendly water based preservative – but put nothing on the inside. Use exterior quality type plywood or similar if at all possible.
N.B. Don’t obscure the owls access hole. vegetation etc.
Needs cleaning out in the late autumn and fresh wood shavings (pet bedding) added.
If there are not any natural roost sites close then a second box might be needed to encourage breeding – as the male often roosts separately (but close) to a breeding female.
Barn Owls like boxes a lot and they can adopt a box any time of year to roost; they actually nest April-May-June-July.
Barn Owls have special protection in law and you need someone with a Schedule one license to inspect (disturbance) in the breeding season.
2)TAWNY OWL: Best location is attached to a tree inside a wood.
Place inside a wood, 2 or 3 metres up. Don’t look directly in a box if you think there might be an owl in it (they can fly at your eyes). Nesting April/May/early June).Plans for Tawny-Duck Nest Box (click on link) suitable for Tawny Owls or Goldeneye or Mandarins depending on location and/or adaptation.
3) LITTLE OWL: needs an open site
Need an open site (like a Barn Owl tree but can be on the side of a building). Only 2m up. Nest May/June. Plans for Little Owl (click on link)
