"I have about 35 nests at 6 sites for swifts but I'm a bit unsure about the best way to place them. Some of my boxes are placed close to each other but it seems that the birds choose boxes with some distance between them.
I had seven boxes located on three different walls at my home and got one box occupied on each wall, it was then that I started to suspect they might prefer some privacy.
No occupants at the other sites were recorded, but I will open all the boxes soon.
At the moment I am building four internal boxes on my barn gable, facing west, the main reason is to get the nests out of the heat. I measured the temperature in the box next to the occupied box this summer. The maximum temperature reached 42°C!
All three nesting pairs at my home chose boxes with this kind of front plate so it will be interesting to see if it was a coincidence or if it actually has some effect.
Benny has modelled his external boxes on the Model 30, but with a roof sloping at 15°. The material is plywood clad in 1.5mm GRP (Glass Reinforced Plastic) - so they should last for a long time.
It seems that, from a standing start, Benny has considerable momentum!
