An alarming number of advantages

The "shocking" A has reason: it is a plastic product!
From this "disadvantage" I find only positive aspects. The product has been designed with expertise by ornithologists and this is reflected in some important details.
* The front can be completely removed without any effort to clean.
* Fledglings find internal staircase shaped grooves in order to better reach the hive entrance.
* The cottage has a ventilated double bottom.
* Overall, it is well protected against lateral rain while providing sufficient ventilation elements against overheating.
* It can be hung on the back screwed (incl. Spacers) or at the bottom are firmly bolted (still easy to open).
* The colors allow the observers even in dense, green foliage a good orientation, where the house is.

The recommended retail price of 19.99 is the Internet market luckily no iron law. Meanwhile, are with me in the garden four colorful nest boxes next three "natural".
The disadvantage I feel only that there is the Emsa nest box only for small songbirds. Half cavity nesters or even bat caves would certainly put some interesting color accents in a colorful garden. In addition, I suggest that to provide front with a second "plate" that can arise out of the nest box a bird feeder (although feeding in winter should be rather refrain).
