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.

Monday 10th Oct 2011 - Ouagadougou to Accra

Chris Orsman writes: Early rise for a last breakfast at La Source du Sahel, and then whisked off to the airport by Daniel with Aly & Oumar in tow. After being waved off and checking in, I reflected on how lucky we are to have such a team in Burkina. I cannot wait (and nor can they!) to see what they might encounter on the transects and at the ringing sites this season. Having last season caught a few returning migrants from season 1, will they this time find any ready-ringed from Europe?!
A short hop from Ouagadougou to Accra, and a different climate felt when stepping off the plane. Already mid-day, but coastal Accra felt quite cool compared to Ouaga. Off to the usual hostelry, and another afternoon of sorting and playing catch-up with data and emails.

Sunday 9th Oct 2011 - Ouagadougou Forest Park

Chris Orsman writes: An early Sunday morning’s birding at Ouagadougou Forest Park, rewarded first by a couple of pied flycatchers, a smattering of nightingales, and an eventual tally of 13 wood warblers. The largest group was of 6 and these seemed to be associating with (or followed by?) a small group of Red-billed Firefinches. We heard a little bit of feeble winter pewing, but also 1 or 2 moments of winter “twittering” too. This further boosted the confidence re catching later on, although not sure whether they’ll have arrived as far south as our possible study areas in Ghana just yet. A few fruit bats were also spotted huddled together in a tree high above the footpath. I think they were a few of the remaining straw-coloured fruit bats that apparently amass here in August, in trees alongside the busy road at the West entrance to the park. By November they will have gone, and regroup further south in places such as central Accra.

A late breakfast at a new place for me – un-named, so when asked what we should call it when writing out a breakfast receipt, the proprietor suggested “le Coin des Amis”. I hope it sticks!
The rest of the final day in Burkina is ensuring Aly & Oumar are completely au fait with the laptops, data entry and saving, and emailing. I try and fail to install any software to go with their GPS’s, but no great shakes for the moment.

Saturday 8th Oct 2011 - Wood warblers and nightingales, Ouagadougou

Chris Orsman writes - Next day back at the monastery, we tried a recorded playback of the full breeding-ground “pew” of a wood warbler. With no luck early on, we then switched to full song, and in the next net round caught 1 right next to the source. Oddly enough no other birds in thatround of 6 nets, except for a nightingale! Very nice indeed.

Next round no wood warblers, but the third and fourth produced 1 each, both in the exact same spot by the mp3 player. Are they easier to catch now on passage when they are vocal, than later on when they seemed, last season at least, to be quieter? Moved the mp3 player to a spot with a nightingale croaking nearby, and subsequently caught a second of these. Another garden warbler was also caught, so not a bad morning for migrants.
Following news of Wales’s win over Ireland in the rugby, a “relaxed” afternoon of catching up on expenditure, and a few pointers to Aly regarding data entry. Not that he needed it – he was well under way with putting ringing data in before I got involved. Good man!

Friday 7th Oct 2011 - Ringing at the monastery

Chris Orsman writes - Our first ringing session this Friday morning resulted in 63 birds caught, so a good training session, and included 1 garden warbler. There were evidently plenty of nightingales around, and thought early on that I heard something resembling wood warbler “winter pewing”. I was later near convinced, with a clearer more typical breeding-ground call heard, and ultimately saw one bird. Definitely more than one call heard though.

This afternoon the Oursi guys had their laptops seen to, getting a French version of the operating system installed. Plus they had all the relevant other software in French too, so nothing lost.

Thursday 6th Oct 2011, Ouagadougou - meetings and monasteries

Chris Orsman writes - Meetings throughout much of the morning, for various members of the team at different times, but eventually we’ve sorted out much of what little things need sorting for this year’s work to go ahead. Not my favourite activity, discussing budgets and contractual agreements! Some more installing of various spreadsheets for the guys to use on their laptops, but then I hear that tomorrow the Naturama computer technician will be around, and able to change their operating system to French. Great news, but it will mean that all I’ve installed will be lost and will need re-installing post-update!
After getting the go-ahead from the Father Abbot on the phone this morning, he wanted to meet us when we arrived at the monastery to set our nets ready for the following morning. He was delighted to be of assistance. With minimal modification to create net rides (we had one ready-made – a ride cut for putting up telegraph poles: ideal), we put up 6 nets; plenty for a morning’s training. Would we catch more than we did last October though? Only 3 birds each morning then! This site does look promising, with loads of shrubby cover. It seems that the grounds of the monastery are fenced off so that livestock cannot wander in, encouraging plenty of scrubby growth and rank grass. Nets set and furled just before dark, we head back to town.
Back to La Source du Sahel, for spaghetti and tomato sauce, with a baguette of fried minced beef and onions. Same as last night, and would prove to be the same every night! Who needs variety when it’s so tasty and excellent value?

Wednesday 5th Oct 2011, Ouagadougou

Chris Orsman writes - Breakfast today was at possibly my favourite local eatery, and the only one in the area that’s open twenty-four-seven, La Source du Sahel. Had the “usual”, of a cafĂ© au lait (a generous teaspoon of instant coffee on top of a large dollop of sweet condensed milk in a glass bowl, hot water added from a well-used flask – to be slurped from a spoon until the bowl has cooled enough to pick it up!), and a delicious Ouaga baguette stuffed with an oily omelette. All served in the shade from the 7am sun, next to the Rue de Charles de Gaul, one of Ouaga’s busiest commuter routes into the city centre.
Handing -over of equipment today, much relief for me as was a considerable bulk! 2 old laptops included, donated to the project for the Burkina team to be able to input all of their data as they go along, and email it to us at opportune stages during the season. Then to the office, to find that Idrissa and Georges are not around, but no matter, as there’s plenty to do. Meet up with Mohamed, who tells us that our hopes for some ringing training in Ougadougou Forest Park may not be possible. It seems a bit of a blow, but apparently they couldn’t accommodate only because the park staff are preparing for a visit of pan-African conservation dignitaries on the 8th, otherwise they were very keen. That’s great news, for next time at least. However, Georges has already armed Mohamed with an alternative to investigate, a monastery some 25km south of the city. Some introductions to the laptops first, and it’s clear early on that the software in English is not going to be easy for Aly & Oumar. Why didn’t we think of that before?!
Lunch next to the office, boiled rice with delicious sauce arachid, or groundnut sauce, seasoned with dried fish. We then head off to pay a visit to the monastery, arriving mid-prayers, so we seek some shade next to a nearby barrage. Despite the heat of mid-afternoon, there’s loads of bird activity, mostly rainy-season breeders, such as weavers, bishops and resident finches, all in and out of the long grasses at the lake shore. From the same grasses the calls of tawny-flanked prinias, and in the middle distance a dead tree in the lake is home to a dozen or more long-tailed cormorants.
Back at the monastery we ring a gong to announce our presence, and one of the elders agrees to see us. Not foreseeing any problems, he does suggest we should speak with the Father Abbot, and in his absence we are given his number to call him first thing the next day.

Tuesday, 4th Oct , London - Ouagadougou

Chris Orsman writes - Today we know that the season really is underway when I’m woken at 3 ready for my 4am taxi to the airport. Some last minute packing to do of course. Rather a lot of luggage it has to be said. The early flight leaves on time to Brussels, followed by an onward delay, and then a diversion to Cotonou in Benin, before at last I arrive 6 hours late in Ouagadougou. Although it’s been hot in London lately, the 29C greeting me at 2100hrs as I leave the plane for the steps down to the tarmac, well, still a bit of a shock, even after a few trips here now. Through the usual checks, including being beckoned by the surly-looking customs guys who wanted to see in my luggage, and at some rather odd looking equipment within! Just as before, when I said it was for our work with Naturama, our project partners here in Burkina, smiles of recognition arrived and then a quick wave of the hand to usher me through. The familiar faces of Aly, Oumar and Daniel are there to greet me, and a welcome sight too! Lots of catching up to do, and a chat well towards midnight discussing what was to come this season, and, more immediately, during my week in Ouagadougou.
