Though I promote bluebirds, these nesting sites are NOT just for our native bluebirds! All native cavity-nesting birds need a place to raise a family — they have many of the same challenges that bluebirds have to find proper housing and habitat. Some of those species, such as the Carolina Chickadee, generally has only one brood/nesting cycle per year. I tend to go into more details of all the wonderful cavity-nesting birds–the native ones–that we should also allow (and by federal laws never EVICT) from our nesting boxes — that place with a roof we like to call home for bluebirds. Stay tuned in as I develop this page. Enjoy this gorgeous video of the Tree Swallow and the Eastern Bluebird. The Tree Swallow is another favorite cavity-nester I like seeing in my nesting boxes, as long as this species does not fight with the bluebird. There are ways of working around both species so they can nest side-by-side by “pairing” nestboxes.
