I enjoy watching birds and studying their amazing migrations. As a biologist with a background in conservation and ecology, I have collaborated with different projects in Portugal, Africa and Central Asia. I am particularly interested in animal movement patterns and behavior, adaptation of species to land-use and climate change, and the role of common species in modified ecosystems. I am also driven by the urgency of contributing with strong scientific evidence to improve nature conservation.
To address the problem of the declines of the Afro-Palearctic migratory birds, my PhD research will focus on three broad questions: which attributes and strategies of species contribute more to the declines? When during the nonbreeding season are species more vulnerable to ongoing threats? Where are the largest habitat losses taking place and how these may be exacerbated by climate change?
Migratory birds undertake
epic journeys connecting oceans and continents, awing people across the globe. Sadly,
as spectacular as these seasonal movements are, many populations of migratory
birds are in decline due to human threats, but tackling
their conservation is challenging, as for most species many mysteries of their
migrations remain unknown.
Scientists believe birds migrate to
increase their energetic efficiency:
put simply, birds migrate in pursuit of better access to food, warmer
climates and less competition with birds of their own and other species. On the
other side of ...
Birds undertake epic migrations across the globe. Knowing no borders, they connect many countries - and even the seas beyond national jurisdictions – in the search for safe heavens where to rest, refuel and spend the winter. But these are no easy journeys. Migratory birds face multiple threats and many populations across the world are facing steep declines.
Conserving migratory birds is thus
a shared challenge that hinges on close cooperation between countries. Unfortunately,
more often than not, this is not the ...
