Uso de datos de teledetección para identificar áreas de migración e invernada relacionadas con los efectos de las condiciones ambientales en la aves migratorias en África

Abstract

The Sand Martin (Riparia riparia) is a bird that has been tracked on all continents from Central and South America to minor Asia; from Europe to Africa. For this case we will focus on the bird within the African territory because; Through the use of remote sensing data obtained from satellite image catalogues, we will look for the correlation between the annual survival rates of the sand martin reported by Professor Szep Tibor of the Nyíregyháza University and the NDVI and EVI vegetation indexes to find out if there is a correlation between the vegetation of the African continent and the survival rates of the sand martin bird; thus, we’ll know the areas of stay or migration of the birds throughout the four seasons each year. To do this, we will use many softwares and tools that will allow us to obtain, classify and categorize the data that we get; thus, we‘ll get information and data that we can use in a GIS software to display maps for us to visualize the data and the information that we found. After assembling the information calculated in the software, the maps indicate that throughout each year the birds will begin their migratory trajectory from north-central Africa (sub-Saharan sector) and at the end of each year the birds will want to arrive to the coasts of Africa in spring. However, a lot of birds have a preference for the coasts of southwestern Africa (specifically the coasts of Mozambique, located at west of the island of Madagascar).
