Stunning Tree Swallow in a Nestbox Jigsaw Puzzle

Part brainteaser, part assemble-it-yourself art, this challenging, wildlife-themed puzzle is great for improving muscle memory.

This male Tree Swallow appears to be quite taken with this particular nestbox ... that look says "mine, all mine." Photographed in late March 2016.

These small bluebirds have shown up almost a month later than last year, and the initial flocks are much smaller, too. Also absent at this time are the greyer females, which at the same time last year were already here. Nevertheless, it's still a wonderful experience to see these little birds in action over the water and in the skies.
