Bought, unpacked, hung. and as soon as I was inspected by X different birds disappeared in the house the same evening two nest boxes were covered as quarters for the night, and the timing was perfect, because it has snowed in the same night for the first time this year. I specially chose this nest box because I have seen many different nest boxes in and around my garden and va have spotted tit. Since Blaumeisen my 'garden darlings' are, I also wanted to do something good for them. And since then, are blue tits and Wren (e) the first ones to nibble on my various feeding grounds in the garden. The quality of these nest boxes is top, 'woman' had to open no problem, unpack it to remove the suspension and then hang up. It was easy, much easier than my other nest boxes made of wood or concrete timber, since I always had to wait for male help. :)) Just buy it !!!
By the way, the birds occupy my nesting boxes for all winter in my garden. One is always a 'guard' in the box, the other flies out and then is' Wachablösung'das I find I particularly funny and shows me how grateful are our birds over these quarters !!
