The project

Our knowledge of ecology of migrants in their wintering grounds is extremely poor and severely hampers our ability to explain these declines and conserve this group of species. We lack even basic information about when birds arrive, the habitats they use and how they move around Africa.

The aim is to understand how Palearctic-African migrants use and move around the different vegetation zones found in West Africa, ranging from the semi-desert Sahelian region in Burkina Faso to the lush tropical rainforest in southern Ghana, and whether habitat change may impact them on their wintering grounds.

During the temperate winter of 2009/2010, using point count methodology and mist-netting, we recorded migrants along a degradation gradient at five different stations on a north-south transect. In 2010/2011 we plan to re-visit these sites as well as roving further afield to get a broader picture of migrant habitat use.

Sunday 7th Oct. Last morning of ringing training

A  4th wood warbler tagged!  This is proving a little too easy.  With Roger’s continued tracking we’re building up a great picture of the species of trees selected by the birds.  In time we’ll get a good idea of the “home range” of each bird, ie the area within which a bird roams around during the course of the 2 weeks or so that the tag lasts. Also caught today were 1 pied flycatcher and 1 common redstart.  Danaë and Carlo consider methods for sampling the invertebrates that are in the various trees being used by the wood warblers.

Aly does a great job with his interview for the film crew, painting a vivid picture of life in Oursi and his hopes for the future of nature conservation back home and across the whole of Burkina.
The p.m. is split between preparing all the gear to be taken by the Oursi team, and a trip into town for some filming of the market. Sadly, there’s not much going on as it’s a Sunday, so the crew resolve to try again when things will inevitably be a lot busier during the week!
