Atlantic Fulmar reaches the Pacific?

What can we learn from this one?

Thanks to Nick for these intriguing photos. I am pretty sure these guys at Scilly Pelagics will have some thoughts. :) Surely it’s a strong possibility that Atlantic Fulmars sometimes reach the Pacific- and it must be possible the other way round too!

“Martin,

I observed this Fulmar on 16 September 2015, northwest of Point Barrow (72 34.526, -161 12.527), Alaska, while conducting bird surveys for U.S. Fish and Wildlife Service. This bird stuck out to me because a) it was the only fulmar that I had seen that day while conducting surveys in the area, b) it was a much darker color morph than any that I’d seen in recent days while in the Chukchi, c) the color of the bird was much more olive/blue-gray than the browner-gray dark morph birds I had seen in the northern Bering and southern Chukchi, and d) after reviewing photos I noticed that it had a relatively concolorous rump and tail, which from my limited knowledge, might suggest a non-Pacific subspecies of northern fulmar, such as F. g. glacialis.

After doing a little research on the matter it appears that there are indeed some Pacific birds that can show a concolorous rump/tail and I am not sure what other characteristics are indicative of an Atlantic bird, or if my photos are good enough to show that.

All the best,

Nick”

Japanese Cormorant genes in Europe?

‘norvegicus’

Eh what? A third taxon has been mooted, suggested, put forward for NW Europe. It is genetically separate from carbo and sinensis and appears more closely related to the Japanese or Temminck’s Cormorant Phalocrocorax capillatus. It’s not ‘news’ though it managed to stay off my radar. Good ol’ Brett R. stirred the pot as we sat seawatching at Flamborough. Richard Millington as ever has been very helpfully added more detail. The Sound Approach crew mention it in this book. ( I wonder what norvegicus might sound like?).

The seminal paper is:

Marion & Le Gentil (2006): Ecological segregation and population structuring of the Cormorant Phalacrocorax carbo in Europe, in relation to the recent introgression of continental and marine subspecies.
Cormorant at Gullfest- Vardo, Varanger, April 2012. It seems probable that the majority of Cormorants here will be 'norvegicus' more closely related to Japanese Cormorants than the other European taxa- carbo and sinensis.

Cormorant at Gullfest- Vardo, Varanger, April 2012. It seems probable that the majority of Cormorants here will be ‘norvegicus’ more closely related to Japanese Cormorants than the other European taxa- carbo and sinensis.

In a rather fascinating nutshell, whilst exploring the genetic makeup of Cormorants, Marion and Le Gentil discovered that a proportion of the population, especially in Arctic Norway appeared more closely  related to the Japanese or Temminck’s Cormorant.

They have named these birds, subspecies nova: norvegicus, explaining:

“…usual P. c. carbo formed two coastal populations, the real P. c. carbo ‘‘C’’ mainly in the western part of the range (United Kingdom, coastal France), and also in Norway and Sardinia, and ‘‘N’’, branched to the Japanese Cormorant P. capillatus and probably isolated by glaciations, mainly present in the Nordic range (Norway, but also on the coasts from Sweden to Brittany), we named P. c. norvegicus.”

 “We show the existence of a third group, N, an unexpected new subspecies (we propose to name P. c. norvegicus), mainly present in Norway and Brittany but also in Sweden, Denmark and The Netherlands, all regions near the sea (Fig.4). It is genetically separated from the Western population Cand appears more related to population S … and…to P. capillatus [Japanese Cormorant] ….”

Varanger is near the north-eastern end of the range of old ‘carbo’. It is by extrapolation from the Marion & Le Gentil paper likely to consist of 90% plus norvegicus. Is also represents the Cormorants nearest to the Northeast Passage and the Asian Pacific Rim where Japanese Cormorants could have colonised from.

I wondered if the genes of Japanese Cormorant in norvegicus translate to phenotypic characters. Japanese Cormorants have a carbo-shaped gular pouch angles and in a brief survey seem to have a higher proportion of white filoplumed birds than ‘western’ carbo in breeding dress  and more extensive white area behind the bare facial skin. The white filoplumes have a curious look in many Japanese Cormorants, tending to look longer and yet sparser in number, ‘wispy’.

So I dug out my few photos of cormorants in Varanger. Hmmm… interestingly they all had some white filoplumes and some seemed to have more white in the facial pattern than I expect for typical carbo.

It’s very preliminary, but rather fascinating :)

Varanger Cormorants (perhaps norvegicus) in March 2012 at Gullfest. 

Especially check out the amount of white in the head pattern. Not all had this much white. It would be interesting to see other photos of Cormorants from Varanger. Tormod Amundsen and Anders Mæland are already on the case.

Fea’s Petrel

‘nough said

Picked up by Andy Malley and  Brett Richards most of the ensemble at Flamborough were delighted. Thanks guys. I rushed off to find signal in the hope that those further north would score too. The resulting communications via social media and ‘twitches’ to watchpoints along the east coast meant the wheeling pterodroma was recorded at multiple sites by lots of people. A triumph for modern birding  and AT LAST a British record for me :) Photos skilfully phonescoped by Mark Newsome off Whitburn Fea's type Whitburn 210914 M Newsome

Happy chaps

Swinhoe’s Petrel – another much closer!

Off Lanzarote Pelagics

Got a lovely note from my Spanish friends who are always a great encouragement. They got  close Swinhoe’s Petrel coming in to the chum 2 days ago (12th September) in the Banco de la Concepción area, north of Lanzarote . Do you remember we had one though more distant and no photos, 2 years ago in the same area?

This one looks like it has a metal ring on. Notice too the flight shape- quite different to the hunkered attitude and angle wings of Leach’s Petrel. Beauty!

Interesting discussion on the bird and the ring HERE.

From Dani and Jose with photos by Juan Sagardia. Well done guys!

Cory’s Shearwater variation

with Scopoli’s Shearwater bits

Chris Gibbins

I took pics of as many Cory’s Shearwater types as possible.  We saw one clear Scopoli’s Shearwater, and of course hundreds of Cory’s.  One (presumed) Cory’s was interesting as it matches what Steve Howell refers to  as ‘probably the maximum permissible tongues for Cory’s Shearwater– a clear but short  tongue on P10, plus others on 9 and 8.  He shows an example of such a bird off Cape Hatteras (USA- eastern Atlantic). The general impression was therefore very different to that seen on typical Cory’s. The structure to my eye is no different to Cory’s (within range showed by Cory’s), similarly so the  dark grizzled and rather brown head…  so an interesting bird. For example of Scopoli’s Shearwater in the same waters see HERE.

Beautiful Seabirds

Chris Gibbins

Another stunning pelagic trip out on the Banco de la Concepcion saw Chris Gibbins catch up with stunning seabirds in sub tropical conditions. Here’s a selection. All photos taken mid-August 2014.
