It’s getting rather tedious and repetitive to report that once again there was no mist… When I went to bed last night at 3:30am and Peter took over the watch, there was low cloud clearly lit up by the lights and even 4-5 birds that I saw dropping down and flying just below the cloud level. This was looking encouraging and we thought Peter might wake us in just 1/2 hour… but it was not to be and the cloud lifted and the birds vanished with the stars coming out once more. 18 ringers were up at dawn (actually, I confess – when I woke at 5:15am and saw it was clear, I had an extra hour’s kip!) and at the 15 or so nets opened to catch any migrant that had arrived over night. The grand total for the day was just 11 migrants in the bush nets and then the redeeming Barn Swallows once again – giving a daily total of at least over 100 – 108 to be precise. This makes the grand total so far this year at only just over 1,200 birds – of which hardly 100 have been migrants other than Barn Swallows!! This is pretty much unheard of and at this rate it’ll be the worst year since 1987 when just 2,400 were ringed – though all of those would have been non-swallows making this even worse! There is the December session to redeem the totals, and still a week of possible nights here…
Toby and Keith had put up some additional 4-5 nets in the old original ringing site along the entrance road to the lodge in the hopes of increasing the catch – even the Afrotropical catch. Surprisingly they caught very few though did produce the first Spotted Flycatcher of the season.
Those ringers for who it’s their first time here are beginning to wonder if it’s all just stories – that of 1,000s of birds in just a few hours – and I don’t blame them! We did catch a retrap Nubian Woodpecker which was very nice to have – the first known adult bird retrap I’ve handled and good to make some notes on. It was a shame that Bruria from Israel and John Musina (Nairobi museum) had to leave today without seeing even one night of mist and real Ngulia action, though both seemed to have enjoyed their time anyway.
Due to it being so quiet, it was perfect to do the Eurasian Roller survey and raptor road count that I started last year and hope to do at least once per year while here at Ngulia. Keith, Toby, Mike and David kindly offered to take me in their Suzuki Maruti (not the world’s most spacious of vehicles…!) and so we set off at about 11am with me standing up through the open roof between Mike and David. For the Rollers we use the Distance Sampling method of recording the distance from the road for each bird seen and the distance travelled for the transect. This is then fed into the Distance program which will give you an estimate of overall density of birds in a given area. I’ve not done the Distance calculations but we saw a total of 42 Rollers today, some of them just a metre or two from the road.

But it was the raptors that really made the day – particularly a large, light brown Accipiter first seen chasing and trying to catch a cisticola (tho’ the cisticola was too agile for the Accipiter and escaped being lunch) and then mobbing a Wahlberg’s Eagle in a tree. It had heavy dark barring underneath, a plain throat, bright yellow eyes and a very clear supercilium – that made it very much an adult female Eurasian Sparrowhawk Accipiter nisus – the first record I’m aware of for Kenya for c.5-6 years and one of what must be less than 20 records ever. Toby managed to get a very reasonable shot of it:

Not long after that with a herd of very red elephant as a backdrop, we watched a wonderful aerial display of a Brown Snake Eagle with a snake being harassed high in the sky by first one Steppe Eagle, then another, then a pair of Wahlberg’s Eagles joined in the fray doing some steep diving display flight for boot and then finally a massive juvenile Martial Eagle came hammering in from about a km away and laid into first a Steppe Eagle which turned up-side-down with talons bared about 1,000feet up in the sky and then the Martial went for the other Steppe which was not far behind one of the Wahlberg’s – all of them spiralling and towering way up in the sky… Meantime over to the left a ways was the female White-headed Vulture, an increasingly rare bird to see and definitely one to really watch out for these days.

Total count for the day was as follows:
Wahlberg’s Eagle – 7
Steppe Eagle – 13

Brown Snake Eagle – 3
African Fish Eagle – 2
Eurasian Sparrowhawk – 1
Bateleur Eagle – 6
White-backed Vulture – 9
Ruppell’s Griffon Vulture – 7
White-headed Vulture – 1
Secretary Bird – 3
Augur Buzzard – 1
Gabar Goshawk – 1

Well – it’s 2a.m and the cloud is somewhat high – at least there is cloud and it’s not starry and clear, but unless it drops down further, we’re unlikely to get much of a catch again. I’ll post this and head to bed again and let Peter take over in an hour… Tomorrow I leave with Tito and head fo Lions Bluff Lodge – exactly 53km due south of here. I’m meeting up with Albert from Mwamba together with three volunteers (Sam, Al and Nick) to go and set nets in front of a spot light by the lodge to see if there is a similar effect as we have here at Ngulia. If it works, it could be very very interesting to compare with what we catch here – and you never know, we might even catch a bird ringed at Ngulia!
