Tree Swallow

Tree swallows have returned to San Joaquin for a few weeks now. We didn't see any eggs, but saw nesting activity and watched, rather close, as they flew into their nest box, hardly bothered by the presence of loud children nearby.

Here is a video (not mine) of one sitting on its nest box at San Joaquin. Look at its glorious blue coloring, and not a thought of its own beauty. 

NestWatch has plans for how you can build your own nest box for these birds. A fun woodworking project perhaps for future years.
