Number 14 all well

Just to update – number 14 is still living in Bioko, fishing and flying so his tracker is still functioning. Not too long now and he will be getting the itch, along with all the other mature ospreys, to start flying North. Fragile wings against global winds.

Vendace update

Bassenthwaite from Noble Knott

Bassenthwaite from Noble Knott

A couple of weeks ago Ian Winfield of the Centre for Ecology and Hydrology gave a talk at the Kirkgate at Cockermouth with updates on the state of the Vendace in Derwentwater and Bassenthwaite. The Vendace is a good indicator of water quality and has had a shaky few years here, for some time being considered extinct, in Bassenthwaite certainly. However, with the work done on lowering phosphate levels there has been a number of sightings including a photo that made local headlines at the end of January.

The BBC picture is taken from a second or two of video in Derwent water 20m down where the vendace zooms out of the murk and bumps at speed into an inoffensive perch. Difficult to know which was the more surprised!

(As vendace are a deep water fish, it is highly unlikely that any fishing osprey could catch one.)

Spot the Tropical Christmas



Whinlatter v Bioko. Where would a bird rather be?

At 5.00 am this morning Number 14 was alive and well and moving around his habitat on the southern side of Bioko. Although rainy at the moment he has a nice Christmas weekend to look forward to with temperature’s dropping to 24 degrees C. with lots of sunshine.

Ho! Ho! Ho!

Bega’s Tracker signal ??

Over the past week or so we have been watching Bega  anxiously as her tracker seemed to be signalling from one place. This can indicate one of a number things, either that her tracker has stopped working, or it has fallen off (unlikely) or that she has perished. We are, of course, hoping it will be the first, although we know that it is just as likely to be the latter. The tracking device works by solar power so if the panel falls face down it will stop working. As the are is remote it is unlikely we will be able to find anyone to go and look at the last place it signalled. But if you know of anyone in Guineau Bissau  with access to GPS please let us know!

Remote dangers

Checking Bega’s satellite tracker before fitting, Summer 2016

Flying into remote and dangerous areas is the norm for ospreys, particularly for those young birds making the migration for the first time. Every beat of their wings could bring them in range of water or banish them into sand; every dive could plunge them into crystal seas or into polluted sludge; every fish could be healthy or sick; every human encounter could be benevolent or inimical. Every day could be the first of many or the last. Satellite tracking can tell us a lot about the routes ospreys take, the heights they reach and the speed they go, but it can’t tell us the things that really matter to the bird. It doesn’t tell us the near misses with disaster, it doesn’t say if the water holds fish or not or whether there is a catch or empty claws. It doesn’t monitor exhaustion, dehydration, starvation, disease or injury.

From over 60 years of studying ospreys we know that only about 20- 30% reach adulthood to reproduce themselves, and this is the same for most species. For ospreys the majority of these fatalities occur in the first migration. Our own birds have proved this time and again, starting out so hopefully into the unknown. So for Bega, the travel inland into Guinea Bissau, an area where we know other ospreys have perished, is very worrying. Why has she chosen to leave the Senegal and Gambia estuaries? There seems to be water, but of what quality? Are other ospreys thriving there, or are there none?


Bioko Boy Arrives

Yes!!!! He’s made again to winter quarters on the island of Bioko, Equatorial Guinea! This will be his third visit to the island since his initial flight in 2013.

First satellite hit on the destination 2pm, October 12th for  2016. No 14 is probably fishing now off the South coast, rainforest area. (photo Wikipedia Commons  Falcanary)


As a reminder here is the first part of his journey this year. Left Lake District on September 16th and reached Algeria by 19th September. (From there he has taken a slower course Algeria 19th September to Bioko 12th October)


Siblings – the time of their lives.

Now here’s an interesting map! It shows Bega, to the west, No 14 to the east and the last known position of our missing chick VO in 2015.

Bega seems to be exploring the coast down to Guinea Bissau, This is a low lying country – highest point 984′ (300M) above sea level,  with a large estuarine and island mangrove coast line. This initially looks good for an osprey population but according to statistics it is one of the poorest nations in the world due to constant political coups, and there are severe problems with agriculture and overfishing. How, might this impact on fish eating bird life in the area? However, Bega has already done better than V0, the chick from 2015, who we lost transmissions from further North last year(red and yellow spot on N Senegal border).

No 14 has flown from Burkina Faso  through Togo and Benin to Nigeria and looks to be heading back to Bioko. Hooray!


Bega -Senegal


St Louis, the old French capital of Senegal. This looked like a good place to stop as, considering its proximity to the Sahel, it is a very watery place. Indeed, so watery that it is considered to be the place most threatened by rising sea levels in the whole of Africa.

There are large marshland areas adjoining the city that in the rainy season (just finishing) are created by the Senegal River overflowing and making grand habitat for flamingos and pelicans etc. There is also the Langue de Barberie , a spit of sand for which (tongue in cheek) I feel I should have an affinity. It stretches 600km along the coast from Mauritania, 25km of which separates the Senegal River from the Atlantic Ocean. (Sept 27th – 28th)

Surely a fishing paradise.

However, this didn’t seem to suit and she is now heading for the current Capital of Dakar.(Oct 6th)

No14 is still lingering on the Ghana Togo Border]


The 24th September download

Two downloads to look at. One for Bega and one for No 14. In comparison they are of great interest as they show the huge area that our UK birds cover in their migrations.

Number 14 is in Mali, the very centre of the Sahara on his way back to Bioko.



Bega has just crossed the Atlas mountains and seems to be on her way to Senegal area..bega-v5-sept-24th-track-position-relative-to-canary-islands
