Spanish Imperial Eagle

At least 4 Spanish Imperial Eagles crossed the Strait of Gibraltar to Northern Africa this autumn (all first-year birds). Three were photographed just after crossing the Strait by my friend Rachid El Khamlichi (in Sep, Oct and Nov respectively).

The 4th bird was satellite-tracked from Andalusia and after crossing the Strait he traveled half Morocco and even visited Algeria for a time before going south and then north to an area near Casablanca. There, apparently its final wintering area, it was photographed in late October by Karim Rousselon (plenty of trees for perching and prey). Photos posted in the blog shown in my signature.
 
You are welcome!
Thanks Mohamed - very interesting

Hope you don't mind - this link should go straight to the article :t:

http://www.magornitho.org/2017/12/spanish-imperial-eagle-migration-2017/
You can post the link as you like! I didn't include it because I thought that the photos are the only additional information in the link and are not central for the news about this known species.

Likewise Mohamed, a very interesting article, also the links to increased incidence of Yellow-browsed Warbler overwintering in the region. :t:
Yes there are more records of Y-b W than in previous years, but still I think the species is under recorded (given the numbers seen in Western Europe).

The same for the Olive-backed Pipit, there should have been more records here as well (Only 4 birds this autumn and all at Rabat by the same observer. But at least, in this case the species needs some efforts to differentiate it from other pipits).

Over the last few years during late December Mohamed, Olive-backed Pipit x 4, plus Red-throated Pipit and Yellow-browed Warbler have all been found overwintering on Fuerteventura (Canary Islands). Perhaps more "hunting" around Rabat and elsewhere in the region, might well produce more overwintering Siberian vagrants?

Cheers
 
Poaching

Authorities and NGOs against the poachers again.

A Peregrine Falcon from Finland and a Saker Falcon rescued from poachers in Morocco last November. The Saker was ringed and GPS-tagged but unfortunately died a few days later.

A similar case happened two years ago with a male Peregrine originated from an introduction project in Sweden. When this bird successfully reared 3 young in 2015, it was the first breeding of the species in central Sweden for 60 years. He was a star in that region. After finishing the breeding season, he decided to have a holiday in Morocco so he can enjoy some sunshine. But at his arrival, he found the poachers waiting for him. In the end he was lucky and was released.

Note: the Saker Falcon is rare in Morocco; this bird is only the fifth record. Although some birds, especially in light phase, may have gone unnoticed because they can easily be confused with Lanner Falcons.

Yes it makes one wonder doesn't it... there was the wild Hungarian bird which was satellite tracked through western Europe and north west Africa to its wintering area at Banc D'Arguin... was this really exceptional?.. :)

Indeed. As in the case of other species, satellite tracking studies reveal some interesting facts. By the way, that Hungarian Saker unfortunately died soon after arriving to Mauritania (but that's normal as 50% of juveniles die before the end of the calendar year, as shown by the study cited in that report).
 
Probably the largest roosting of Black Kites recorded on migration through this flyway.

Watch until the end of the video to see the actual roosts: https://www.youtube.com/watch?v=p074MgiDoNc

Next day, 3 March 2020, over 10,000 have passed just over Gibraltar (see, e.g.: https://twitter.com/gonhsgib/status/1234934220436463622).

I was South of the High Atlas and it was noticeable that there was no migration in the last ten days of February. The first early signs were on 28/29th February.

It is likely to guess that the sandstorm that impacted the Canaries cut off the northerly movement of species and now, like a cork out of a bottle, they are chasing north again.

We did see a couple of Spoonbills that were so badly abraded that they could hardly fly. It is good to know that at least one species waited.

Thanks for mentioning this. At first, we haven't thought about it but now I also think it's very possible this is the case. These sandstorms can indeed stop birds from migrating further, not just slowing their migration but the actual halt of movements. This photo of White Storks standing in the middle of a sand dust is a perfect example (the photo which was taken by Arnoud van den Berg is in the middle of the page).

Morandini, V., González, E., Bildstein, K. et al. 2020. Juvenile dispersal in an uninhabited continent: young Spanish Imperial Eagles in Africa. J Ornithol 161, 373–380. https://doi.org/10.1007/s10336-019-01732-0

ABSTRACT
The Spanish Imperial Eagle (Aquila adalberti) disappeared from Africa as a breeding species in the 1960s coincident with a general decline of their populations in the Iberian Peninsula. Because of a combination of successful conservation actions and a general change in human attitudes, the Spanish Imperial Eagle population has been increasing in Iberia from 103 pairs in 1980 to more than 500 breeding pairs in 2018. As a consequence, the number of juveniles that cross the Strait of Gibraltar into Africa has increased recently. Abundance and distribution of potential prey should affect young eagles’ behaviour and could be a limiting factor for a potential re-colonization of previous North-African populations. Additionally, determination of temporary settlement areas is crucial from a conservation point of view. Conservation actions in these areas, particularly reduction of juvenile mortality, are a priority to facilitate future reestablishment of breeding populations of the species in North Africa. Here we report on the dispersal movements of juvenile Spanish Imperial Eagles marked with GPS-GSM transmitters in Andalusia (southern Spain), some of which crossed the Strait of Gibraltar into north-western Africa, an area that does not have populations of the eagle’s main prey, the European rabbit. We analysed the differences in dispersal patterns and temporary settlement behaviour in the two study areas. We found that dispersal movements were greater, temporary settlement areas were larger, and individuals stayed longer in areas and moved greater distances among them in Africa than in Iberia. We believe that our results are best explained by applying the Marginal Value Theorem, which predicts that individuals will leave a foraging area when the availability of prey drops to similar levels of those of the surrounding environment. We suggest that the increase in the records of the species in Africa could lead to a recolonization of the species in Africa based on birds coming from the “source” Iberian population, but only if the Iberian population continues to increase. We recommend that conservation measures must be established in these temporary settlement areas in Africa.
