Captured this image at a marsh in Lima Peru back in June of 2015. He decided to puff up his feathers. In an image I posted back then, one can see he's about half this size. C&C welcome.

Such a gorgeous, tiny bird. When we stood on the edge of that wetland and he popped out of the reeds to pose for us, my heart skipped a beat. Great shot with him all puffed up -- maybe a defensive stance? Yes to NR.
