speriamo che ce la faccia.....zona difficile, inospitale e pericolosa per tempeste di sabbia, speriamo che Blue YZ abbia abbastanza riserve di energie ...
invece di andare lungo la costa si è diretta verso l'interno del deserto nel cuore dell'Algeria, territorio inospitale per un falco pescatore,
ora è a 500 km dalla costa e entro 24 ore avremo notizie....dita incrociate !!!
Satellite Tracking Update: Still Going Strong
Posted on October 11, 2013 by rangeremma
Blue YZ is still going strong on her perilous migration. As of yesterday she was in northern Mali, and was finally starting to make a turn south west towards the coast.
http://blogs.scottishwildlifetrust.org.uk/osprey/She roosted overnight on one of the rocky outcrops that run in a strong diagonal line in this area ( the corner of Algeria, Mauritania and Mail) from NE to SW, giving a visual marker for her to follow. If she had kept going to the due south she would have ended up in an inhospitable area of real Saharan sand dunes.
If she continues on this SW course she should be able to reach the coast in a couple of days- she still had 1200km to go! She is not out of danger yet but is still going strong!
Q: What on earth is she eating?
A: She is probably not eating at all, unless she is lucky enough to come across an oasis with a fish supply. Instead she will be relying on her fat reserves – this is where chicks with better fledging weights have the real advantage on their first migration.
Q: How long can an osprey go without eating or drinking?
A: A bird can go several days without eating as long as it is getting sufficient moisture and has fat reserves to fall back on. Ospreys usually get all their hydration from their food, but in this scenario, they will drink water directly.
I guess: BlueYZ can arrive the green belt
near Senegal/Mali within two days..
Blue YZ: The latest news 12th Oct
Posted on October 12, 2013 by rangeremma
As promised, updates on news of our young satellite tracked osprey as soon as we have them. We too are on the edges of our seats waiting for each new set of data to see how our youngster is fairing.
As of 9pm last night ( Friday) she was in central Mauritania, still following her SW or SSW trajectory. She is still flying well, at a fairly normal speed, and making good long flights.
On the 10th ( Thursday) she flew over 400km in the day, over high sand dunes and roosted for the night on top of one of them- what a strange place to imagine our Scottish bird!
On Friday she flew about 250km by 7pm, but having gone a bit of a curved route to the east before heading true south again. It looks like she was again roosting on Sand dunes.
http://blogs.scottishwildlifetrust.org.uk/osprey/She is now nearing the southern edge of this desert area and the more fertile eastern region. She is still 1000km from Dakar and the coast though, and some 800km from the inland river where our other young osprey Blue YD ( 2012) is wintering. If she can keep going another day or two , she will be able to reach an area with plenty of fishing opportunities and more hospitable landscapes- fingers crossed!
More news Monday Morning hopefully.
P.S. You may notice that the interactive satellite tracking map seems to have a minor glitch in it at the moment. It is not allocating all data points to the map in correct time order, so it may occasionally appear that our bird is looping back on herself. This is not the case and is just a data error. She is in fact flying directly and determinedly in the right way! Our software boffins are trying to sort this asap, but rest assured the bird isn’t lost or disorientated.
Satellite Tracking Update Monday 14th Oct
Posted on October 14, 2013 by rangeremma
Well it looks like Blue YZ is past the worst of her arduous crossing of the El Djouf Desert and has made it safely to its southern edge. After roosting again on Friday night on the top of sand dunes she flew more than 300 km on Saturday , showing no sign of letting up speed.
The latest satellite data available on shows up to Saturday night, but by then she was safely into an area with water availability and some more vegetated valleys.
http://blogs.scottishwildlifetrust.org.uk/osprey/What a relief she has made it through the most inhospitable par to of her migration journey as far- but what will she choose to do next? More news as we have it.
Satellite Tracking Update 15th Oct: More Good News

Blue YZ has made it out of the desert!!!
By last night she had made it into the greener boundary lands of southern Mali
and has done a hard turn right towards the east and the coast.
http://blogs.scottishwildlifetrust.org.uk/osprey/On Sunday night she had made it to the river Bakoye where she presumably fished
and rested for the first time since her desert crossing.
She is now heading east and is presumably following the river system or other landmarks towards the coast.
Well done girl!!!!!
