It is early spring, and Eastern Bluebirds are back. Our first arrivals at Fair Meadows Sanctuary this year showed up on February 9—a pair that were hanging around the house and feeders in the early morning.
Although natural cavities can be provided by leaving standing dead trees, the easiest way to supply ample nesting cavities is to build and install songbird boxes.
At Fair Meadows Sanctuary, one fact has been made abundantly clear: there is keen competition for nesting sites, both in artificial structures and in tree cavities.
The telltale sign of a Tree Swallow nest is often feathers. In some cases, there are so many feathers, you can’t even see the underlying nest structure of dry grass or pine needles.
