Nest 4 second egg right on schedule

The incubating pair on Nest 4 had tucked their egg below the lip of the cup when streaming started today. 69 was incubating but Mrs 69 took over before 11.00. It wasn’t until around 12.55 that a second egg could be confirmed. We’ll try and establish a time of laying but for now here are a couple of images.

UV continues through Spain

Today’s data update about UV’s migration came at lunchtime. He’s travelling through Spain but not at pace – yesterday he covered just 227 km in around 8 hours of flying. Here’s his route.

There’s a distinct change of direction late yesterday, so what happened?

UV had his normal ‘stop-start’ beginning with a couple of short flights before he set off in earnest around 08.20 UTC. This was his modest first move.

UV’s course was NE until soon after 10.00 when he changed to a more easterly direction. He wasn’t flying at the elevations or speeds he achieved in Africa. Before too long he decided on a break.

The reservoir is stocked with several fish species but UV pressed on. He continued NE, generally no higher than 800m above the terrain below which was a mixture of agricultural and hillier areas.

By 13.20 he was flying east of Toledo and his course was NNE. In the late afternoon he picked up the Rio Tajo (River Tagus), the longest in the Iberian peninsula at 1007 km. His course altered to follow the river eastwards. He stopped at 16.41 and explored several possible roost sites over the following couple of hours before plumping for a view from a hillside beside the river.

Today UV set off – after the usual stutters – just before 09.00. He was curving towards a more northerly direction until about 10.00 when he turned east again. That way lies the area he spent several weeks exploring last Spring after his arduous journey in Africa. Is that where he is going again? If so, for how long? During the first half of his migration he had seemed focused on returning to the UK but his travel in Spain has been less pacy. Time will tell what UV is planning!

More on UV’s first day in Spain

UV arrived in Spain shortly before 07.00 UTC. Recently he has been flying non-stop for 8 or more hours but he had a brief pause shortly before 10.00 at the Embalse de Guadalcacin.

UV spends 20 mins or so by the reservoir

This is an important site for the Spanish osprey population. Early in the Andalucian reintroduction program a pair of non-reintroduced ospreys tried to breed there but failed. This article has more about the Spanish reintroduction program. By 2012 successful breeding was occurring at Guadalcacin so UV will have seen other ospreys yesterday morning.

Data reveals UV didn’t stop again until 17.39 by which time he had covered 392 km in the day. He had flown over the relatively low Sierra Norte mountain range and stopped in an area NE of Almadén, a town famed for its mercury mines.

Although UV has spent many an hour perched near mines in Senegal he chose a more traditional spot for his roost last night.

Another egg for Nest 2

A third egg for Nest 2 was ‘due’ before nestcam streaming began today at 10.00. EB half stood to shuffle her eggs at 10.08 but obscured the view. But when 37 arrived to take over incubating at 10.47 he – and we – could see three eggs.

Mrs 69 was standing or lying in the nest cup on and off from around 14.30. 69 wasn’t very supportive.

There were still no eggs for the Nest 3 pair at the time Mrs 69 laid.

A bit more on UV’s last full day in Africa

On Thursday UV was nearing the Moroccan coast when he turned back and stopped in a valley about 1.25 km inland.

UV spent the rest of the day taking short flights around three wooded areas up to about 13 km south of the coast.

UV roosted in the southernmost wood.

Today’s email arrived extremely early but UV had already left his first roost in Spain. More later on UV yesterday.

UV is in Spain

After a frustrating Thursday for UV, prevented by gales from crossing to Europe, he set out early this morning from an inland roost and possibly took advantage of a drop in wind levels just before dawn. He was offshore by 06.05 UTC and flew 25 km over the Strait of Gibraltar to reach Spain before 07.00. He was at low altitude in the two fixes over water.

UV carried on with no recorded pause until last fix at 16.33. To last fix UV has flown 3949 km since 13 April on his migration.

Paul’s graphic shows UV’s travel through Spain to late afternoon. His course is taking him towards Madrid.

Paul’s weather forecast for UV tomorrow:- “Inland, away from the coasts, weather is Spain tomorrow will be fine and reasonably clear, winds light to very light, variable.”
