I have long wanted one in the garden, since while we get plenty of birds coming into the garden for food and shelter, I am not sure how many actualy nest in the garden. So I would like to give them a helping hand in that department. I have though been put off by not not knowing where to put them and which way they should face. It seems different 'experts' have differing ideas on this. Shelter from hot sun, cold winds and prevailing weather seem to limit the options, as do the need to discourage predators etc.
In my garden i have a group of very tall pine trees at the end of the garden and it is on one of these i would put a nest box. The garden is orientated Northwest - Southeast with the house facing side of the trees looking south east. The prevailing winds cut across the garden at a right angle, but the garden is also open to the east so catch easterlies quite a bit too. On the plus side neighbour's trees (also pines) shelter our trees to an extent from the prevailing winds.
My other main concern would be branches or lack of near the nest box. The trees are pretty bare of branches to well above the height i can safely fix a bird box and i am concerned that this would be a problem for any fledglings. On the other hand what branches there are might give predators (such as squirrels or magpies) easier access to the nest.
Can any one help me out. I would really like one or more nest boxes but am very confused about putting one up.
Thanks
