Round bird house

Round birdhouse for small birds (around sparrow size birds).

Most birdhouses are squared but birds build round nests
So… there is a lost of waste spaces and mother needs to use more energy to warm the eggs.

This birdhouse is round, has small drains for aeration and water/liquids evacuations.
Walls are thick enough to correctly insulate interior.

There is several options for the bottom of that birdhouse:

1. “Narrow” or “large” round bottoms,
2. Bottom with wall support to attach the house to a wall/tree trunk
3. Bottom with feet to set it on a flat surface.

All bottom options have 5 holes for (up to 4mm diameter) screws.

Parts are already oriented to avoid use of supports.
Looks really soft and pretty with “fuzzy” outer perimeter walls.
