Bird Cams Around the World

Wildlife Diary Monday 29th October
Posted on October 28, 2013 by rangeremma

Our chick Blue YZ is still in Guinea Bissau, she seems to have stopped for now dotting around a river and it’s tributaries roosting and fishing which is just what you’d expect from a young Osprey. Whether she stays there remains to be seen so we’ll watch with interest will she add some more stamps to her passport?...

Our two young ospreys in Africa continue to do well and the good news is that our 2013 chick Blue YZ seems to have found herself a winter territory in Guinea Bissau for now. Her latest satellite tracking data show her sticking around a delta area between the Cantanhez Forest National Park and the Cufada Lagoons National Park. We hope this area which is criss-crossed with numerous rivers and waterways, and lightly populated with small farms, will be a safe place for her to stay.

I hopefully will have time tomorrow to post all the details for you on our interactive map.

Osprey Satellite Tracking Update 8th Nov
Posted on November 8, 2013 by rangeremma

Both our young ospreys are doing well and are still in their respective wintering areas in Africa. Blue YZ has moved a whole 5 miles in the last few days, to an area slightly downriver of her previous location. It is interesting in this close-up map to see her exploring relatively minor river channels and roosting at night on the boundary between the jungle and field edges.

Meanwhile Blue YD continues to hold his favourite territory on the Senegal/ Mauritania border. His home range in this area is about 7miles square and varies very little from week to week- simply one bend in the river east or west as the fancy takes him.

One wonders if he is now so well established that he is chasing away this years new arrivals – younger ospreys.

Grave Concerns for Blue YZ
Posted on November 19, 2013 by jonathan

Unfortunately it looks like there may be a problem with our young satellite tracked osprey, Blue YZ, whose fascinating first migration we have been following so avidly this autumn.

Despite several attempts over the last week to access data from her tracking device, the satellite is not showing any new data at all. The last confirmed GPS data we had was on the 5th of November, when she was in Guinea Bissau in an agricultural field in a delta area.

Since then the tag has not transmitted any new information to the satellite, which means there are two possibilities. The first is that the tag has simply malfunctioned and stopped working, which is quite possible (you may remember we suspected that this may have happened with last year’s bird, Bird 44). The second possible explanation is that the bird has died and the tag has stopped transmitting as it has fallen to the ground or has been destroyed. It is possible Blue YZ has been predated, succumbed to exhaustion or even to human interference.

The only way to be certain which of these scenarios is the explanation of our birds fate, would be to visit the site to see if we can find evidence of a body, or find out from locals what they have seen. Unfortunately this area is politically very unstable at the moment and with the official foreign office advice being not to travel there, this is not practical . We have been struggling to find any local contacts in the area who might be able to visit the area on our behalf, but so far with no luck.

This highlights huge challenges faced by young migrating ospreys – and the importance of continuing to study these birds in this way, to ensure a greater understanding of their behaviour for conservation in the long-term. We will of course continue to try to access the satellite tag in case it does restart but this is unlikely, and will keep you updated with any further developments.

We may never know with 100% certainty what happened to this young osprey but we do know that she has taught us so much this year – not least through the fascinating story of her mammoth migration. On that positive note, Blue YD is alive and well and we will bring you news of his recent movements tomorrow.
