This interested me to the extent that I've done a little bit of research on it
![shrug :shrug:](./images/smilies/shrug.gif)
. Lots of places sell it but there's only one model. I wondered what it was made of and it seems its a tough kind of plastic - do blueys/greats go for plastic ??
Also, I don't trust suction pads at all at all but I wondered whether inch-wide Velcro attached to both the rear of the box and the window pane would do the trick. Can't bear the thought of it falling off whilst chockablock with yelling baby blueys
Can only find one unclear reference to a, I think, "plate" thingy which is put onto the back of the box (from inside the house) in the evening. Seems that maybe when the room light is on the birds would see movement.
I'd have to put a notice in the window telling the window cleaner not to clean the window for 3 months
There's one (Amazon if I remember correctly) which is priced at £18.99 but - it's a BOGOF !!!!
