The article provides guidance on creating suitable nesting boxes for birds in Lithuania, focusing on the different types of birdhouses and their specifications. Closed birdhouses with a round entrance are primarily used for birds that nest in cavities, as they offer protection from wind and rain. Specific measurements for entrance holes are recommended for various bird species, such as blue tits, great tits, sparrows, and starlings, to ensure proper access and deter predators.

In addition to closed birdhouses, the article also discusses half-open birdhouses, which cater to species that prefer more exposed nesting sites, such as those found in snug corners, under roofs, or among tree branches. These birdhouses provide a different structure compared to fully enclosed options, acknowledging the diverse nesting preferences among birds and adapting accordingly.

The guidance emphasizes the importance of placing these nesting boxes in appropriate environments like gardens, parks, and forests to promote the return of bird populations. By understanding the specific needs of various bird species, enthusiasts can effectively contribute to conservation efforts while enjoying the presence of returning birds during the nesting season.
