Sunday 6th –Mon 14th Jan 2013 Back to Ghana, and a visit from the experts!

The New Year is underway, and the Ghana wood warbler team is augmented by the arrival from the UK of project manager Danaë Sheehan and head of species recovery Norbert Schaffer from the RSPB’s International department, and Franz Bairlein, from the Institute of Avian Research in Germany and one of the world’s foremost bird migration experts, all here to visit the study site and formulate a programme of fieldwork for the remainder of this season and for those to come.

After a brief visit to Ghana Wildlife Society HQ, we set off for the study site, the old team feeling a little anxious as to what first impressions the ‘new’ members will get from the wooded farmland at Pepease.  For our first morning in the field we walk the usual transect route that we follow to do the regular wood warbler survey.  Our own first impressions are that the vegetation has not dried out anything near as much as it had done by January of last year.  The air is dry, suggesting the harmattan may be just starting, but very little burning has taken place.  Thankfully we’re able to find a few wood warblers for the visitors, but here in the eastern section of the site, where no wood warblers were ringed last month, no colour ringed birds are spotted.  The following morning we head for the western side, where last month we caught and colour-ringed 11 birds.  This time we spot 4 of these, and a decent number of unringed individuals too.  Of note was the number of birds that could be seen with incomplete tails, demonstrating nicely that they are well into their winter moult.  All in all a great introduction to the site, and aside from the field visits some very interesting discussions about the future directions for the fieldwork were had.

Danaë, Norbert and Franz continued their Ghana visit with a trip to the lowland forest zone, whilst over the next 3 days we undertook a full site survey, with additional waypoints through a site extension encompassing the area inhabited by Black Star, our second tagged bird from last November. We then tackled the issue of some habitat recording for the areas occupied by the three tagged birds from November and December, and also spent time dissecting some of the whole-site habitat survey from the end of last season, before we embark on mapping any changes in late March.  Throughout this period we note that after the dry air of the 7th and 8th of January, the humidity levels have risen again.  There really is no sign of the harmattan yet....

Our study-site tasks completed, we then planned our own foray into the forest zone.  With the local wood warblers in moult rendering them near un-taggable, and after our experience last season of failing to catch any in January and early February (save the one tail-less individual!), our next job is to visit as many of the forest blocks in the south as possible. The aim is as last season – to prove or otherwise the presence of wood warblers in the forests that we have not yet visited, to improve the model that will help to predict the presence or absence of wood warblers elsewhere.  On top of this, we will attempt to measure wood warbler densities in the varying forest types and qualities, and where time permits, the adjacent farmland.  Should prove pretty interesting!!
