Introduction -- pt. 2. Regional aspects -- pt. 3. Methodology -- pt. 4. Synthesis.Each year shorebirds from North and South America migrate thousands of miles to spend the summer in the Arctic. There they feed in shoreline marshes and estuaries along some of the most productive and pristine coasts anywhere. With so much available food they are able to reproduce almost explosively; and as winter approaches, they retreat south along with their offspring, to return to the Arctic the following spring. This remarkable pattern of movement and activity has been the object of intensive study by an international team of ornithologists who have spent a decade counting, surveying, and observing these shorebirds. In this important synthetic work, they address multiple questions about these migratory bird populations. How many birds occupy Arctic ecosystems each summer? How long do visiting shorebirds linger before heading south? How fecund are these birds? Where exactly do they migrate and where exactly do they return? Are their populations growing or shrinking? The results of this study are crucial for better understanding how environmental policies will influence Arctic habitats as well as the far-ranging winter habitats used by migratory shorebirds.Studies in avian biology ;no. 44.Shore birdsCanada, NorthernShore birdsAlaskaBird surveysCanada, NorthernBird surveysAlaskaarctic ecosystems.arctic habitats.bird population.bird science.bird watchers.birds in the cold.birds in the winter.books about birds.books for animal lovers.conservation of birds.distractions for kids.educational books.environment books.environmental ecosystem.head south for the winter.home school science books.interesting books.leisure reads.life sciences.nature lovers.ornithology.passion books.planet earth lovers.shorebirds.vacation books.wildlife.winter habitats.zoology.Shore birdsShore birdsBird surveysBird surveys598.3/309719Bart Jonathan531545Johnston Victoria Helen1962-1677404MiAaPQMiAaPQMiAaPQBOOK9910818623303321Arctic shorebirds in North America4044247UNINA
