Bear River Refuge
Bear River Refuge MIGRATION MATTERS Summary Student participants increase their understanding of migration and migratory birds by playing Migration Matters. This game demonstrates the main needs Grade Level: (habitat, food/water, etc.) for migratory birds, and several of the pitfalls and 1 - 6 dangers of NOT having any of those needs readily available along the migratory flyway. Setting: Outside – pref. on grass, or large indoor Objectives - “Students will…” space with room to run. ● understand the concept of Migration / Migratory birds and be able to name at least two migratory species Time Involved: 20 – 30 min. ● indentify three reasons/barriers that explain why “Migration activity, 5 – 10 min. setup isn’t easy” (example: loss of food, habitat) Key Vocabulary: Bird ● describe how invasive species impact migratory birds Migration, Flyways, Wetland, Habitat, Invasive species Materials ● colored pipe-cleaners in rings to represent “food” Utah Grade Connections 5-6 laminated representations of wetland habitats 35 Bird Name tags (1 bird per student; 5 spp / 7 ea) 2 long ropes to delineate start/end of migration Science Core Background Social Studies Providing food, water, and habitat for migratory birds is a major portion of the US FWS & Bear River MBR’s mission. Migratory birds are historically the reason the refuge exists, and teaching the students about the many species of migratory birds that either nest or stop-off at the refuge is an important goal. The refuge hosts over 200 migratory species including large numbers of Wilson’s phalaropes, Tundra swans and most waterfowl, and also has upwards of 70 species nesting on refuge land such as White-faced ibis, American Avocet and Grasshopper sparrows. -

The Cuckoo Sheds New Light on the Scientific Mystery of Bird Migration 20 November 2015
The cuckoo sheds new light on the scientific mystery of bird migration 20 November 2015 Evolution and Climate at the University of Copenhagen led the study with the use of miniature satellite tracking technology. In an experiment, 11 adult cuckoos were relocated from Denmark to Spain just before their winter migration to Africa was about to begin. When the birds were released more than 1,000 km away from their well-known migration route, they navigated towards the different stopover areas used along their normal route. "The release site was completely unknown to the cuckoos, yet they had no trouble finding their way back to their normal migratory route. Interestingly though, they aimed for different targets on the route, which we do not consider random. This individual and flexible choice in navigation indicates an ability to assess advantages and disadvantages of different routes, probably based on their health, age, experience or even personality traits. They evaluate their own condition and adjust their reaction to it, displaying a complicated behavior which we were able to document for the first time in migratory birds", says postdoc Mikkel Willemoes from the Center for Macroecology, Evolution and Climate at the University of Copenhagen. Previously, in 2014, the Center also led a study mapping the complete cuckoo migration route from Satellite technology has made it possible for the first Denmark to Africa. Here they discovered that time to track the complete migration of a relocated during autumn the birds make stopovers in different species and reveal individual responses.

We saw all but a few of the endemic birds we were seeking (and the ones missed are mostly rarely seen), and had good weather throughout, with little rain hampering proceedings for any significant length of time. Among the avian highlights were five pitta species seen, with the Blue-banded, Blue-headed, and Black-and-crimson Pittas in particular putting on fantastic shows for all birders present. The Blue-banded was so spectacular it was an obvious shoe-in for one of the top trip birds of the tour from the moment we walked away. Amazingly, despite absolutely stunning views of a male Blue-headed Pitta showing his shimmering cerulean blue cap and deep purple underside to spectacular effect, he never even got a mention in the final highlights of the tour, which completely baffled me; he simply could not have been seen better, and birds simply cannot look any better! However, to mention only the endemics is to miss the mark, as some of the, other, less local birds create as much of a stir, and can bring with them as much fanfare. -

Chapter 8 Migration Studies
Chapter 8 Migration Studies 100 Migration Studies Overview Theme he Pacific Flyway is a route taken by migratory birds during flights between breeding grounds in the north and wintering grounds in the south. Steigerwald Lake National Wildlife Refuge plays an important role in migration by providing birds with a protected resting area during their arduous journey. Migration makes it possible for birds to benefit the most from favorable weather conditions; they breed and feed in the north during the summer and rest and feed in the warmer south during the winter. This pattern is called return migration — the most common type of migration by birds. Through a variety of activities, students will learn about the factors and hazards of bird migration on the Pacific Flyway. Background The migration of birds usually refers to their regular flights between summer and winter homes. Some birds migrate thousands of miles, while others may travel less than a hundred miles. This seasonal movement has long been a mystery to humans. Aristotle, the naturalist and philosopher of ancient Greece, noticed that cranes, pelicans, geese, swans, doves, and many other birds moved to warmer places for the winter. Like others of times past, he proposed theories that were widely accepted for hundreds of years. One of his theories was that many birds spent the winter sleeping in hollow trees, caves, or beneath the mud in marshes. 101 Through natural selection, migration evolved as an advantageous behavior. Birds migrate north to nest and breed because the competition for food and space is substantially lower there. In addition, during the summer months the food supply is considerably better in many northern climates (e.g., Arctic regions). -
