Nest boxes can be fixed to walls, trees or buildings. If the site is exposed, it
is advisable to position them so the opening is not exposed to full sun or the wettest
Choose a spot between 10 and 15 feet above ground level, where there is easy flight
access to the box opening.
To get the most pleasure out of your nest box(es), site them where they can be seen
from the house and where you can gain easy ladder access, for inspection and cleaning.
Above all, make certain that they cannot be reached by any marauding cats.
If you can site them near your boundary, you stand a good chance of attracting birds
from some distance away.
When fixing a nest box, try to position it at a slight angle, so that rain is directed
away from the entrance hole.
It is advisable to clean out nest boxes during October or November.
Any fleas or other parasites that have built up over the breeding season, should
be killed off with boiling water and any unhatched eggs should be removed.
Once the box is clean and dry, remember to add a little hay or wood shavings, to
encourage the birds to use it for a winter roost, which may well reserve the box
for the next breeding season.
During the breeding season, it is very tempting to open the box to see what is happening.
This should only be done with great caution, when the birds are away from the box,
since your presence may well cause the birds to desert the nest.
If you tap lightly on the side of the box, any birds inside will probably fly away

The soundest advice is quite simply NOT to inspect the boxes at all, during the breeding
Contrary to popular belief there is no ‘best’ time to put up bird nest boxes.Birds
will quickly become familiar with boxes erected during the latter part of the year
and may well use them for winter roosts, especially if they already contain a little
hay or wood shavings.
Boxes erected before the end of February stand the best chance of being used that
season, but it is not unusual for Tits to take over boxes as late as April, if there
is a shortage of natural sites.
House Martins may well use boxes erected in July, halfway through the breeding season.The
important thing is to site the box correctly and in a position where the birds will
be safe from potential predators.
