Phase IFoundation

Background

Overview

Highlights a critical aspect of global biodiversity loss, the need for international cooperation in environmental conservation, the impact of human activities on ecosystems, and the role of technology in monitoring and conservation. It's relevant for Environment & Ecology, International Relations, and Science & Technology.

Migratory birds undertake seasonal journeys across continents, playing vital ecological roles such as pollination, seed dispersal, and insect control, and serving as indicators of ecosystem health. Their conservation is crucial for maintaining biodiversity and ecosystem services globally.

Phase IIStatic core

Facts & tables

Key facts

Global Decline

Over 51% of migratory bird species are declining globally across all major flyways.

India Specifics

Long-distance migrants visiting India from the Arctic are declining more rapidly than resident birds.

Ecological Roles

Migratory birds regulate insect populations, disperse seeds, pollinate plants, and support food webs.

Conservation Strategy

Requires international, flyway-wide strategies addressing threats across entire migratory lifecycles.
