Blue Tit bird house

thingiverse

The current entrance hole measures 28 mm in diameter, making it an ideal size to attract small tit species such as blue tit, black tit, European crested tit, willow tit, or marsh tit. Birds are better protected from predators when nesting on the balcony birdhouse. If a cat tries to reach into the bird house with its paw, it won't be long enough to catch chicks at the bottom of the nest. Similarly, if a squirrel or lerot attempts to enter, birds can stand guard and defend their nest from the balcony, rather than from the bottom of the nest or outside. The balcony birdhouse provides better protection against bad weather conditions as well. In a traditional mailbox-type birdhouse, the nest is more exposed to wind, rain, and sun compared to one with a balcony. The balcony acts as an entrance vestibule, breaking air currents and catching water droplets if it rains inside the birdhouse.
