We have another go at netting, near the spot where bird 2 spent a lot of time last December. Quite ironically the first bird we caught was a nightingale! Full biometrics were taken but no tag put on this bird – saving the tags for the nightingale study site. After over an hour of trying, however, we actually caught a wood warbler. We were not getting too excited however, as a quick check of the tail showed that there was no way we were going to be able to tag it. Those feathers present were all at various stages of growth, but the central pair was missing altogether. The state of moult in the wing suggested that perhaps it was about half-way through, at about 3 or 4 weeks to go before completion. If all the wood warblers are like this, then will we be able to tag any at all? We put colour-rings on it in any case, as we did the 4th bird in December, seeing as with the latter we were able to relocate it a couple of times without a tag. Perhaps we can do it with this new one.
We spend the rest of the morning surveying the remainder of the site for wood warblers. Not as good as yesterday, with just 5 encountered, but still more than on this same section last December. A particular highlight was the first woodchat shrike that I’ve seen on the study site.

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.

16 Jan: Looooooooooong journey
After a pleasant, albeit small, breakfast of sausage, egg and beans (got beaten to it by hungry students), the Yellow-billed Kite circling overhead the hotel patio helped introduce us a new friend, Iben from the Denmark Ornithological Society (DOF). She had overheard some bird talk at the table and was also working on a project with the GWS on a ringing project. Just enough time to twitch the Western Grey Plantain Eater and a few Cattle Egrets before we shared the car to GWS office - it was sad to leave our new found acquaintance so quickly with so much to talk about.
Emmanuel (our driver) and Nick (co pilot and prince of part of Berekum!) accompanied us on the day long journey through Accra, to Kumasi where we were to meet Bee, Chris and Roger. A few African Grey Hornbills, Hooded Vultures and Pied Crows wafted overhead as we motored by never ending stalls selling fresh fruit, tiger nuts, chilli boiled eggs and other groceries. Finally we stopped to meet our new team mates, receiving a warm welcome before Ian and me, plus Bee and Oppong (our chef and driver) set off. Chris, Roger and Emmanuel went the opposite direction to the Wood Warbler site.
Our guest house, some 3 hours later, was fine with comfy beds and after some acrobatics, string and impressive use of a kitchen knife, my mozzie net was erected by Oppong. A quick fast-food dinner of fried rice and chicken in town and bed after a long tiring day. Roll on birds!!

Sunday 15/01/12 Surveying, but not catching
First morning in the field, and to start we have a go at catching. We set the net where we caught our first two last November. We give it an hour but after no response from any wood warblers, we pack away and set off to survey the site.
A whinchat is present at the start, and by the end of the route (half of the usual transect) we encounter a total of 11 wood warblers. Some of these are only registered as a result of playback after the end of the standard 5 minute count. Elsewhere we record 10 willow warblers, 4 melodious warblers, 3 pied flycatchers, 2 spotted flycatchers, and 1 garden warbler. Wood warbler numbers are up on this section of the site since last December’s final survey, and so too willow warblers.
No news from the UK (as it is the weekend after all!), but we assume that Ian and Vicky are on their way and hopefully arriving in Accra tonight!

15 Jan: Two more ringers
Ian and I arrived late today in Accra , to join the team on Monday. Ian as Senior Research Ecologist for BTO and I as a keen volunteer BTO ringer from Kent. First a good rest was needed after a long plane journey, so after possibly the world’s most expensive taxi, the Pink Hostel welcomed us to our first Ghanaian bed for the night. Rooms had all the mod cons, just a quaint take the lid off the cistern and flush by hand loo to keep the problem solving part of the brain working. Ghana Wildlife Society will pick us up tomorrow to get the car to that will take us up to Berekum.

Saturday 14/01/12 Leaving for the field
All goes to plan and we leave Accra by 0900, and after a shop in Mpraeso for groceries we make it to our digs mid afternoon.
Straight out into the field to show Roger the lay of the land. The whole place seems a whole lot drier, not surprising considering the desiccating effects of the harmattan winds, and large parts of fallow have been burned. There’s a strange arid, dusty stillness about the place, and scarcely a bird to be seen or heard. I hope things improve tomorrow.

Friday 13/01/12 Back with Bee
Arriving for breakfast we spot Bee sitting outside with a cuppa. It was brilliant to catch up with Bee again, and to hear all about her past month, finishing off the nightingale tracking, and touring around Ghana with Ed. And to cap it all, a decent breakfast too! Seems there’s been a change of management – thank goodness!
A morning at the office to sort through the gear, meeting up with Japheth, Nick and Oppong once more, and then a trip to Legon Uni in the afternoon to discuss the possibilities of a supply of satellite images for the wood warbler study site. A few sundry purchases at the nearby Accra Mall (it could be any-mall in any-town) and we’re ready for the off tomorrow.

Thursday 12/01/12 Leaving the cold behind
After a pretty mild spell of weather in the UK over the Christmas break, it looks like there may be a rather cold snap on the way. Just about the right time then to be heading back to West Africa! A meeting on Tuesday ahead of departure was attended by new volunteer Roger, a very experienced fieldworker and ringer in Africa, having spent several years in both Cameroon and Uganda. Whilst I head for Heathrow for a leisurely afternoon flight, Roger is already in the air from Norwich to Accra via Amsterdam. Fingers crossed we can find each other at the other end!
With everything going smoothly up to arrival, a few nervous moments as the crowd thins at my carousel – has my luggage made it? Roger arrives very soon after my flight, and he finds his bag straight away. Mine must have been at the bottom of the pile on the plane, as thankfully it eventually appears! A blast of heat on leaving the airport – is it supposed to be this hot at this time of year? 29°C seems excessive at 10pm! (Despite escaping the UK cold, I admit I was grateful for the a/c at the hotel later on) A short cab ride to the hotel, followed by the inevitable mix-up with the booking, now all that remains is to find Bee in the morning.
