My heart raced as I reached my hand into the bag. What if I broke them? What if I let them escape? Then my fingers found a familiar grip, and before I knew it, I was holding this bird just like I had the warbler. Now that I was the bander and not just the releaser, the vibration of their heart felt different. Their safety was in my hands. My own heart slowed, and I took a steadying breath.

Maneuvering the veery so that I could grip their right leg in my left thumb and forefinger, I slipped the open band over their leg. Now they were ready to contribute to science!

"This bird will be forever connected to you," Jim reminded me after we'd sent the veery flying back into the brush. My heart fluttered happily

I barely caught the flash of brown out of the corner of my eye, but Kevin had a clear view. He followed the flight path of the bird until they landed on the far side of a small channel lined with arching sedges. Despite the bird's pinstriped camouflage blending seamlessly with the tall grass, and having never before seen one in the wild, his identification came instantly: American bittern!

Bitterns hunt alone, mostly at dawn and dusk, and are said to be easier to hear than to see. Their deep booming, gulping calls travel far across marshes, but the male "thunder-pumpers" are vocal only during their spring mating season, and so it's not even that easy to hear them. Add to that bitterns' decline in parallel with the decline of their wetland homes, and we'd resigned ourselves to admiring their mystery instead of enjoying an encounter.

From a distance, the forests of July look like a lush tapestry of green. But when you step into the loosely woven strands and take a closer look, the leaves are etched with feeding trails, dissected by holes of all shapes and sizes, and covered with the debris of life. It's a principle of ecology, of course, that every Being is food for someone else.

Feeding styles vary. Some invertebrates are "leaf folders," while others are "leaf rollers" or "leaf tiers." All of these insects and spiders use silk that contracts as it dries to shape leaves into shelters.

I set out to find examples of all of the leaf architects.
