Western Bluebirds are cavity-nesters. They naturally build their nests in holes—which are often found in dead or dying trees, called snags. However, because of habitat destruction and the disappearance of many natural cavities, people are now filling the void by providing human-made nesting boxes.
This year, as rookie monitors, we were responsible for six boxes. Between March and July, we visited the boxes every two weeks and recorded what we saw—peeking inside to discover the appearance of those first bright blue eggs, followed by naked nestlings with wide-open beaks, feathered fledglings in a now-crowded nest and finally an empty nest that signaled our success.
In the end, we helped fledge 31 bluebirds. In total, our Audubon chapter fledged 522 Western Bluebirds and 6 Tree Swallows. Below are some highlights of a pretty awesome year.
