Quant a Carles Oliver

When I was a child I was already fascinated by nature. I was a teenager begun my passion for birds and later for reptilians, mammals and butterflies. Is for many years I'm an active member in different bird reseach and monitoring activities. I had not enough and that's why I decided to become a bird guide. Des de ben petit que he sentit fascinació per la natura. Als setze anys va començar la meva passió pels ocells, que s'ha anat ampliant progressivament a rèptils i amfibis, mamífers i papallones. Des de fa anys que participo en múltiples activitats relacionades amb la recerca i l'estudi de les aus. Fa temps que vull descobrir per altre gent la natura de casa nostra i és per això que vaig esdevenir guia ornitològic.

Red-rumped Swallow expanding North

Deixa un comentari

The Red-rumped Swallow (Cecropis daurica) is going North its breeding territory in Western Europe. The numbers of this swallow in Catalonia are also growing up. There are two main breeding populations, one is at North beside the French border but the biggest one is at South and inland in both Lleida and Tarragona provinces. Is in this bigger population where I’ve found this spring some couples breeding in new sites.

Red-rumped Swallow (Cecropis daurica) is breeding in new places in a 50 kilometers North of Balaguer town, an area immediatly situated South of Pyrenees. I’ve found until tree nesting couples in different non-used farm houses near the village of Camarasa. The swallows are in an area with no breeding records for this species before.

Red-rumped Swallows use to nest inside small or medium size non-used human constructions as well as under bridges and other structures. It prefers to have near the nest some small river or other fresh water.

It seems clear that this species is gonna be commoner in Catalonia in next years and is even possible that is gonna arrive as a nesting bird to some Pyrenees valleys as a natural process due its strong expansion in Western Europe.
