Breeding origin and spatial distribution of migrant and resident harriers in a Mediterranean wintering area: insights from isotopic analyses, ring recoveries and species distribution modelling

A new article published in the Journal of Ornithology, with participation BacLab, highlights how the combination of information derived from ring recovering – a conventional technique for the study of the movements of birds – along with more modern techniques such as spatial modeling and analysis of stable isotopes, can be very useful to better understand the distribution patterns of birds and the differential origin depending on the place and time of year.

The study has the participation of researchers from the University of Barcelona, ​​the Doñana Biological Station and the Environment Canada.
