Dick Oehlenschlager, Biology Collections Manager at the Science Museum, studies the life cycles of plants and animals as they respond to seasonal changes. It’s a discipline known as phenology (fee-NOW-low-gee).
Dick began tracking seasonal events in the environment when he was twelve years old. By the age of fifteen, he was making observations of bird behavior, nesting dates, and migrations on "data cards." Later, he broadened his studies to include the plants and other animals of Wadena County, an area he still studies today.
