Read the following passage.
A. Monarch butterflies are famous for a multi-generational migration that links Canada, the United States, and central Mexico. Each autumn, millions of monarchs fly south to oyamel fir forests in Mexico's mountains, where they cluster on trees through winter. In spring they head north again, breeding along the way so that later generations reach Canadian milkweed patches. No single butterfly completes the entire round trip; the journey is a relay across generations. A careful description of monarch butterflies starts with what it is before listing exceptions. In Canadian settings, monarch butterflies shows up in both large cities and smaller communities.
B. Milkweed plants are essential because monarch caterpillars feed only on milkweed leaves. Adults drink nectar from many flowers, but without milkweed the species cannot reproduce. Habitat loss from farming, herbicides, and urban growth has reduced milkweed along the flyway. Gardeners who plant native milkweed and avoid pesticides create small stepping stones for migrating butterflies. When equipment or schedules fail, staff adjust routines so the public still gets clear guidance.
C. Scientists tag monarch wings with light stickers and ask the public to report sightings, building maps of routes and timing. Weather systems can blow butterflies off course or delay departure from Mexico. Roost sites in trees during migration nights need protection from cutting. International agreements and community monitors in Mexico guard the winter forests that shelter the dense clusters.
D. Classroom projects raise caterpillars and release adults to teach metamorphosis and migration science. Festival events in Canada celebrate the butterflies' return each summer. Still, population counts at winter colonies have swung sharply in recent decades, keeping conservationists alert. Keeping milkweed corridors and nectar gardens remains a practical way for ordinary people to help. Future upgrades will likely focus on clearer communication as much as new hardware.
