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.
We have observed six species of swallows at Fair Meadows: three of which nest here (Barn Swallow, Tree Swallow, Purple Martin). Of the other species (Cliff Swallow, Northern Rough-winged Swallow, Bank Swallow), we have seen the Bank Swallow only in late summer.
