Nest boxes for birds, mammals and insects - MKW Pracownia

nestbox22df

 

Our website presents a wide range of classic and original nest boxes and shelters for European wild animals.

We produce high quality nest boxes for various birds ranging from the smallest hollow-nesters, such as blue tits or pied flycatchers (boxes with the entrance hole diameter of 2.8 cm) to the largest species living in tree hollows, e.g. tawny owls or goosanders (where the entrance hole diameter is as big as 15 cm).

We also offer a rich variety of summer shelters for extremely beneficial bats and dormice as well as different sizes of hotels for insect pollinators.

Apart from wooden boxes, we also sell boxes made of woodcrete designed mainly to be installed on building walls.

Since 3rd January 2011, which is the day the shop’s owner, MKW Pracownia Przyrodniczo-Rolna, started its business activity, we have been regularly expanding the range of our products in order to comprehensively serve even the most demanding customers.

Close co-operation with the scientists of the Institute of Zoology of Poznań University of Life Sciences, including Professor Piotr Tryjanowski and others, allows for constant development of our products so that they meet strict European ornithological, chiropterological and entomological standards.

Comfort and safety of wild animals living in our nest boxes is our priority, so if you want to be actively involved in their protection and if you care about the aesthetic value of the world around you, MKW Pracownia products are an obvious choice.

Since the start of 2018 we have been introducing our products to some western European countries, such as Germany, Austria, the Netherlands and Great Britain. We hope our nest boxes earn the same recognition there as they have received in Poland where the brand of MKW is associated with the highest quality product.

INFORMATION

APPROPRIATE USE OF THE PRODUCT

Nest boxes and nesting shelters for birds, mammals and insects offered by MKW Pracownia Przyrodniczo-Rolna are high quality products. Majority of them are made of solid wood, which is natural material, so the following are not grounds for a complaint: cracks, blue stain, bending resulting from drying of wood, knots and natural staining of wood.

It is worth remembering that the ECO line of production comprises products which are not impregnated and whose durability is much lower compared to the products from the PREMIUM line of production which are twice painted with natural linseed oil varnish or another impregnating agent. Thus, ECO nest boxes must on no account be installed high on building walls where the influence of atmospheric conditions is much stronger than among tree branches. In such cases complaints will be rejected.

Installation of ECO line wooden products and woodcrete products is of course acceptable and recommended by the producer, but only after painting them on the outside with exterior paint (ideally the colour of the walls).

All nest boxes on our offer are designed for outdoor use so after the purchase they should be stored outdoors or in an unheated room (it does not concern woodcrete boxes). Too high temperature might cause excessive drying of wood, which results in cracking along the grain.

Using nails, not screws is recommended for installation of the boxes on tree trunks. In commercial forests aluminum nails will be the best.

FAQ

Questions and Answers

The easiest way is playing recordings of swift sounds an hour before sunset from 20/04 to 15/05 and from 20/06 to 20/07. It can be done with a special bird caller (which is more economical when a large amount of boxes is installed in one location), or with an mp3 player connected to a loud speaker put out on the window ledge.

Swift boxes should only be installed high up on building walls (min. 5 metres above the ground) which are not covered with or next to tall obstacles such as trees.

A nest box installed on a tree trunk will never be occupied by swifts because it isn’t their habitat. Other species might take up the opportunity though, e.g. great tits, tree sparrows or redstarts.

Minimum external dimensions of the nesting chamber for swifts: 18.00 x 36.00 x 20.00 (height x width x length) [cm]. The entrance hole: 2.80 x 6.50 (height x width) [cm].

Bat boxes should be installed in groups on trees or south-facing building walls.

Basic types of bat boxes include: Stratmann-type, Issel-type, English-type, surface shelter, embedded shelter.

The most popular and universal bat box - Stratmann-type has the following external dimensions: 39.00 x 23.50 x 9.00 (height x width x length) [cm]. The entrance slit: 2.00 x 19. 50 (height x width) [cm]. The original Stratmann-type box should narrow towards the bottom, in the narrowest place reaching a 2-centimetre slit which bats get inside through.

Standard height is 3-4 metres. In places where it isn’t possible a height of a fence post at 1.5 metres will be enough.

Bug hotels should always be installed facing the sun (preferably right towards the south) in a place shielded from the wind. The best location is on a building wall at about 1.5 metres above the ground.

According to the rules in force, based on bird breeding phenology, optimal time for cleaning nest boxes is between 16th October and 28th February each year.

A hedgehog box can be filled with dry hay or straw.

It’s best to put a hedgehog shelter in a secluded spot in the garden, among bushes – preferably under their branches.
