Накратко на български

Пътищата на миграция на птици и насекоми в Европа се проследяват чрез данни от мрежата от метеорологични радари. Това помага да се разберат моделите на летене при малките певчести птици, които се придвижват нощем и на голяма височина.

Elucidating continental-scale patterns of bird migration with weather radars

Animal migration is a wide-spread phenomenon, which allows animals of many different taxa to take advantage of seasonal variation in resource abundance. Billions of mammals, birds, fish, insects and other animals make seasonal round trips between breeding sites and non-breeding (wintering) sites each year, with huge effects on communities and ecological systems. Migration of course also entails costs, such as the cost of transportation to distant sites. Flying is an energetically comparably cheap way of transportation and consequently billions of birds, insects and bats migrate across the globe each year. Since migration often involves long distance movements it is a difficult behaviour to observe and study, especially for flying migrants. In the case of small songbirds, which migrate at night and at high altitudes, their migratory flights have been nearly impossible to observe directly. However, recent developments in the field of radar biology have now made it possible to use data collected from continental networks of weather radars to study the migration patterns of songbirds and insects over very large scales and over long time periods. The goal of this project was to obtain and analyze data on animal movement patterns from the European weather radar network to map the migration of flying animals over Europe and analyze several aspects of flight behavior during migration. Due to Covid related lockdowns across Europe access to, and processing of, the weather radar data was delayed. Preliminary data from Europe was analyzed, and together with already available data from the US weather radar network some preliminary analysis of flight behaviour was made.

Цел на проекта

Migration is a wide-spread phenomenon which allows animals of many different taxa to take advantage of seasonal variation in resource abundance . Radar is a powerful tool to observe and track migratory flights. In this action I will use the existing network of weather radars to investigate bird migration behaviour in relation to topography, weather and insect migration. A unique aspect of this action is that I will have access not only to the weather radar data, but also to complementary bird ringing and individual bird tracks, as well as data on insect migration from a small scale biological radar. The weather radars will provide data on bird migration patterns at the continental-scale; the ringing and tracking data will provide species composition and individual behaviour at specific points along the flyway; and the small-scale biological radars will provide more detailed information on insect and bird migration patterns at a specific site. Together this will give us a unique overview of the flux and behaviour of migratory animals across Europe, something that has never before been possible. Together this will give me a unique overview of the flux and behaviour of migratory animals across Europe, something that has never before been possible. The objectives of the work packages in this action will be: WP 1: To describe the flux of bird migration in relation to weather and topography across the European flyway, and relate this to insect migration, ringing and tracking data along the flyway. WP 2: To describe the flight behaviour of bird and insect migrants in relation to winds at both a continental and local scale, testing theoretical predictions of how migrants should use winds optimally. WP 3: To describe the nightly initiation and termination of bird migration across latitudes and how it changes with the seasonal progression of migration.
