I visited our long-established local yellow-crowned night-heron nesting site this afternoon. Only one nest was active, but I did find an eggshell beneath it--an entire half, robin's-egg blue with an extra tint of green, about the size of a chicken's egg, and what looked like the rest of the shell fragmented, but still held together. This may not have been the first egg; pairs of these birds typically have laid 4-5 eggs each season. The brooding adult was hard to see, but another adult was perched twenty yards away. The site echoed with the songs of yellow-throated warblers, who share an affinity with the many mature sycamore trees favored by the night-herons.
