Arctic Peregrines in Eastern Europe

Latvia and the (Western) Edge of the Range

peregrein calidus 5 (1 of 1)

Gaidis Grandans

Hello, Martin!

I want to know your ID thoughts about a 1cy Peregrine Falcon, photographed on 3rd October at Latvia. According to “Winter Book” it looks good for ‘Arctic Peregrine’  ssp. calidus = new subspecies for Latvia. Thanks!

Gaidis  Grandans 

Gaidis is writing from from Latvia. He’s the manager of – rare and interesting bird observation in Latvia. 

A reply from MG:

Well this is lovely looking Peregrine. As you say, a bird in its first year. A 1cy.

It is not as distinct as some calidus but well within the ‘wake up and look at this’ range! It shows exactly the kind of features we want to be here if looking for vagrants. Right now.

The rather browner uppers, lots of pale about the head, specifically large pale cheek, rather thin dark ‘moustache’. A pale ‘nick’ under the eye trying to cut the dark moustache off. Rather large pale supercilium- bit broken up. Then check out that underpart streaking- YES! fading to thinner in the middle. What about the vent/undertail. Barring weak and reduced. All in all rather delicious!

How to record such birds?

I have seen similar plumage in similar latitude further north. The range to the north of this bird will appear in books as the edge/ overlap zone of nominate and calidus. I suspect more calidus pass through Latvia given the geography. Some of these will be travelling MONSTER distances.  All such birds should be well documented as calidus and calidus-like records as part of the local avifauna. 

Probably overlooked,  I wonder what the real status of migrants/ vagrants passing through Latvia is?

Cheers Martin

I have lightened this first shot to show the underparts which were in shadow.

Pallid Harrier on Shetland

needs me and Mrs G to be on Shetland too 🙂

Thanks to my bloomin marvellous friends on Shetland, Sharon, me and Yoav the Perlman will be heading north early next week. I just wanted to flag up my hopes. Maybe this chap will still be around. Photographed by Brydon Thomason in one of my favourite places on the planet. As this particular spot is one of favourite birding places in the world, and is best best birded solo- if I tell you where it is I will then have to kill you 🙂 . Brydon has been a friend for nearly 10 years since we met on a very windy day on Foula. Since then we have worked together and played together. I love his passion for Shetland and its nature- which is so wonderfully informed by his knowledge of his native Shetland and its nature. I have guided for him over several years being more than happy to serve the vision of Shetland Nature . Brydon’s business which has grown to be a shining example of its kind.

and he takes bloomin juicy photos (check out the little montage below). This Pallid Harrier, probably still around is no doubt awaiting our arrival. It was found just over a week ago.

We are ready and will soon be on our way!

Shetland here we come!

Hen Harriers – getting a little soapy for the cause

Bath Bomb, Bath Bomb, your my….

Some folk are doing some serious campaigning, information sharing and opinion changing on behalf to save the shocking decline of the Hen Harrier in the U.K. and exposing the underlying issues. I am not one of those-  but I am a big fan of what they are doing and feel I should do more. Well here’s little effort in the hope that my foolishness might encourage YOU if you havent  signed up yet- you just might.

LUSH have produced a Hen Harrier ‘bath bomb’. Sent me one after an unguarded comment, so happy to play the fool.

I need to point well away from myself to those doing the work. Please visit and sign up and support. For more info and action please click on these:

Soapy Hen Harriers?

Lush offer sweet smell of salvation to save Hen Harriers

Lush cosmetics are releasing a new bath bomb named by TV presenter Chris Packham called Skydancer – Far From The Madding Guns, to help raise funds for one of England’s rarest bird of prey, the hen harrier.


Lush soap Hen Harrier (1 of 1)

Knowing the strength of feeling amongst the public, after their hen harrier campaign last year, they wanted to provide their customers with a way of directly contributing to the efforts of protecting this vulnerable bird. By buying a bath bomb, people can personally contribute to the monitoring of these precious few birds. A form of crowd funding, for people who otherwise feel powerless to help.

The money raised from the product will be put towards aiding the RSPB’s Hen Harrier LIFE+ project which is satellite tagging as many hen harrier chicks as possible over the coming years. This strategy allows the UK’s largest and most successful conservation organisation to monitor these birds after they leave the nest.

A Government-commissioned report states that there should in fact be over breeding 300 pairs breeding on the uplands of northern England. However, in 2013 there were no successful nests and the situation has barely improved with just four successful pairs in 2014 and six pairs in 2015 – a statistic that still worries the conservation organisations greatly. According to the report, the main culprit for this decline is illegal persecution associated with driven grouse moors

Lush first got involved with the campaign to protect hen harriers in August 2014 when they linked up with the organisers of Hen Harrier Day, an event set up by Chris Packham, Mark Avery and Birders Against Wildlife Crime to highlight the near extinction of one of England’s rarest and most beautiful birds of prey. Between them a campaign was set up which saw Lush customers sign a politely worded plea to Her Majesty the Queen asking for her help and support in stopping this illegal activity. Over the course of the campaign 20,000 postcards were signed by Lush customers and hand delivered to Buckingham Palace late last year.

In an effort to conserve hen harriers the RSPB and Natural England have been satellite tracking the chicks of these birds to learn more about their ecology and to find out where they might be at risk.

Paul Morton, Lush campaigner says

By helping the RSPB tag as many chicks as is legally and ethically possible, we’re compiling a much clearer understanding of where these birds are most at risk. If you think about it, this should be a project the shooting lobby should welcome with open arms. If they’re as concerned about hen harriers as they say they are, they won’t mind the whole country being updated and informed where roughly every tagged hen harrier across the country is through the RSPBs Hen Harrier LIFE+ project”

 Jeff Knott, the RSPB’s Head of Nature Policy, said: “We are delighted that Lush has come up with this imaginative way of raising awareness about hen harriers and getting their customers involved in their conservation. Everyone who buys a bath bomb will be making a valuable contribution towards bringing this amazing bird of prey back from the brink of extinction in England.”

 Anti-RSPB group, You Forgot The Birds recently issued a statement blaming the RSPB for the failure of five hen harrier nests this summer due to over-monitoring of these nests. However, Government agency Natural England confirmed the failure was actually down to the males from each pair never returning to the nest whilst out hunting miles away, therefore forcing the females to have to leave the eggs un-incubated whilst they went and found food for themselves.

Griffon and Rüppell’s Vultures

More on ID of tricky ones

Guillermo Rodriguez Lazaro

Hi Yoav and Martin,

I saw your post about the Israeli vulture in the Birding Frontiers blog and thought that perhaps I could provide some light about this bird.

The second photo (underparts) shows an indisputable Griffon (repeated above), definitely ruling out Rüppell’s The complete absence of white edges in wing coverts (not only GCs but also in MCs) is diagnostic. Other features which don’t indicate Rüppell’s are the shape and color of the axillary feathers, absence of white edges in UTCs, strong contrast between black GCs and much lighter MCs, etc… I attach a photo of a classic erlangeri adult from below from northern Ethiopia for comparison.

So, as pointed in your post, only the upper parts resemble Rüppell’s, I think that mainly due to the presence of two-rows of dark wing coverts, a feature typical of Rüppell’s (which usually has present 2-3 rows). Additionally the bird’s overall colour is perhaps unusually greyish for Griffon, but this species presents a high variation in this trait and I feel it isn’t a strong feature to discard Griffon. In my opinion, your bird doesn’t fit well one of the striking “pale morphs” Rüppell’s which from time to time are observed in NE Africa (it’s too patterned and browner above), so we should compare with the more classic erlangeri adults.

In both Griffon and Rüppell’s all wing coverts present a dark feather center with a pale edge. In Griffon, only the greater coverts present an extension of black large enough to be visible, whereas in the median coverts the dark part is very limited (due to the broad pale edge) and it’s usually not visible. In Rüppell’s, the pale edge is much finer and thus the dark centre of the feather is exposed and very obvious in the upperwing. However, I’ve found that a few Griffons (Spanish breeders at least; I’m not sure if it is an individual characteristic or just the result of a certain state of moult, though the first option is more likely since these birds seem to present also more patterned scapulars) can show two rows.

In my opinion, your bird is one of these odd Griffons. Detailed analysis of the upperparts pattern shows that the feather edge of the second row (median coverts) is too broad, and concolorous (cream coloured) with the rest of the wing, whilst it is usually whiter and thinner in Rüppell’s. The wing looks very uniform and with the characteristic griffon-colour of the species, instead of the more browner/greyer appereance of erlangeri Rüppell’s. I also attach one photo of an adult erlangeri (again from N Ethiopia), in which these features are evident.

Taking into account these points, I don’t find consistent reasons for considering a Rüppell’s here but just a slightly unusual Griffon. Other characters also support this id, eg the bird silhouette and the blue skin around the auriculars which provides the characteristic Griffon head pattern.

The option of a hybrid is, in my opinion, even more complex: as far as I know there aren’t proved records, though there is at least one suspected individual from Spain which certainly ticks all the boxes:

Hope these comments are interesting for you and help to clinch the id.

Best regards

Rough-legged Buzzard- juvenile at Grindale

Majestic Beastie

Already much photographed mostly in flight, our local wintering Rough-legged Buzzard ramped up the game today. I arrived to find a handful of birders watching our Arctic visitor at ridiculously close range. Feeding on a road-kill hare. It took no notice of us 🙂

How Close?

I had hoped to get pictures of the ‘trousers’/thigh feathering/ tibia feathering. Why? I have noticed when exploring the subject at the Natural History Museum, Tring that there was a potential difference from pale juveniles of the North American form and the European form. Many N. American birds have plain unmarked rich apricot trousers. European birds are inevitable dark (spade-shaped) spotting here- just like on the Grindale juvenile.

I did see a pale juvenile Rough-legged Buzzard on Foula (Shetland) in mid October 2007 in NW near gales. Bet it was North American- just never saw it close enough. Next time!

Rüppell’s Vulture or hybrid

or  What?

Yoav Perlman

On July 15th, Eitan and Judith Kaufman went birding at the scenic Gamla NR in N Israel . This reserve is well-known for its vultures that often fly past the lookout at very close range. Among the Eurasian Griffons, they noticed this very striking-looking vulture, that made one quick pass in front of them:

They sent the photo to several Israeli birders, and immediately the alarm bells went off – from above this bird looked very good for  Rüppell’s Vulture. Hot on the heels after the first Rüppell’s for Israel that was found in May 2014 by Ezra Hadad in C Israel but unfortunately was non-twitchable, we were all hoping that this bird shows better. The image was sent to Dick Forsman, who agreed that this bird had a good potential to be an adult Rüppell’s Vulture of the NE African race erlangeri, but he did clearly state that some bird are virtually impossible to separate from Eurasian Griffon, and that hybrids are known from Ethiopia.

Next morning quite a few birders assembled at the Gamla lookout, and when the air heated up and the vultures left their roost, soon the suspect was relocated. from above it looked very good, but from below – oh no! Pretty identical to Eurasian Griffon! Very plain from below, too plain, especially the undertail coverts. This bird stayed around Gamla for a couple more weeks. This image is by Shachar Alterman:

Googling Ethiopian Rüppell’s Vultures images, I found none that have completely ‘blank’ underparts like this bird. erlangeri is less striking than the C African race rueppellii, but surely pure erlangeri cannot be so plain from below? I wonder if anyone has images of known hybrids either from E Africa of elsewhere in Africa. Have any hybrids wandered into Europe via Gibraltar? Certainly worth looking out for.

Here are some ‘real’ Rüppell’s Vultures:

This is the first for Israel, found and photographed by Ezra Hadad, 5 May 2014. It was on the move with two other Eurasian Griffons and was not seen subsequently. This is a younger bird – probably 3cy – note especially the undertail coverts:
