Tree swallows are a common sight around Shaver's Creek in the spring and summer. You might spot them joyfully dipping and diving through big open areas, like above Lake Perez, as they catch insects on the wing. Here we see a mama tree swallow gathering materials to build her nest. 🪺 Many species, like tree swallows, take advantage of nest boxes during breeding season when there is competition for nesting sites. Adding a nest box to your yard can be a fun and easy way to support local bird populations! Like humans, different birds have different preferences when nesting.
