Life Sciences Gallery: Global View
|
This section shows how Saskatchewan is linked to other parts of the world, especially Arctic and tropical locations. Interactive displays examine connections associated with the climate system and migration. |

One display looks at El Niño, a phenomenon that causes ocean temperatures to rise off the coast of Peru every 2 to 7 years. This alters weather patterns all over the globe and is sometimes followed by La Niña, which has the opposite effect. |
Costa Rican Rainforest
Many of "our" songbirds are actually tropical species that fly north for a few months to breed. They spend much of their time in Central and South America, sharing a range of habitats with resident species. This diorama shows the upper canopy of the Rara Avis ("rare bird") rainforest in February in Costa Rica.

In the canopy of a rainforest, tree limbs are draped with ferns, fungi, lichens, mosses, orchids, and bromeliads. This tree-top forest is home to a tremendous diversity of insects, mammals, reptiles, and birds, including 200 migratory bird species. |

In the Costa Rican jungle, the Harpy Eagle is the ultimate tree-top predator. One of the largest eagles in the world, it feeds on large tree-dwelling mammals like monkeys and three-toed sloths. |
Mackenzie Delta
Every year, birds including loons, waterfowl, raptors, shorebirds, gulls, terns, and songbirds gather in the far north to mate, nest, and raise their young before winter returns. They migrate through Saskatchewan in late May and early June to reach their nesting grounds in the Mackenzie Delta, and return as early as July! |

Breeding birds keep a wary eye out for predators like gulls, jaegers and Arctic foxes. The female Tundra Swan in this display is using nesting material to conceal her eggs before she leaves the nest. |
