Southern Oceans - Three Species of Gull

No Kelp Gulls. Just Dolphin Gull, Brown-hooded Gull and Gray Gull.  See previous posting for Kelp Gull pictures. As I said in the previous post, gulls were only a side dish of gravy compared to the main course of pelagic birding on this trip but gravy was so rich.

Dolphin Gull was seen on the Falklands and during single day visits to Ushuaia, Argentina and Punta Arenas, Chile.  The encounters were short lived but total indulgence. Gray Gull was but a four hour visit to the beach area on the south side of the main port at San Antonio, Chile, a port for the inland capital of Santiago.

Dolphin Gull

The Dolphin Gull is a stunner. Is that bill for real?  At times it looks soft and waxy. This is an adult at Ushuaia, Argentina.

The gray head and dusky tip to the bill make this a 2nd summer bird, meaning was  hatched in January 2018.

The bird in the middle with the coal -dusted head and pink bill with blackish tip is probably a one year old bird. The picture was taken on 1 Feb 2020 so the bird should have been hatched in January 2019. I think my calculations are correct. All the birds around it are adults.  Ushuaia, Argentina

The Brown-hooded Gull

The Brown-headed Gull of South America is very similar to the Black-headed Gull from Eurasian.  The adult shows more extensive black on the  underside of the primaries with a white wedge across the ends of P7-10.   The upper surface of the wing is similar to a Black-headed. 

This adult Brown-hooded Gull is so much like a Common Black-headed Gull. 6 Feb 2020, San Antonio, Chile

This bird was the exception in having in still having a dark hood and intact primaries.  2 Feb 2020, Punta Arenas, Chile.

 Juvenile Brown-hooded Gull,  Note the conspicuous white tips to the primaries. This is lacking on Black-headed Gulls of the same age. 2 Feb 2020, Punta Arenas, Chile.

Juvenile Brown-hooded Gull.  Most had dark tail band like this one but some had wholly or mostly white tails . 2 Feb 2020, Punta Arenas, Chile.

GRAY GULL

The Gray Gull is a beautiful bird. It has a restricted range for a gull. It nests on inland lakes of the Atacama Desert inland in northern Chile. Sub-adults and adults in the non breeding season occur along the coast of Peru and Chile. My four hour encounter with the species on a beach just south of the port of San Antonio, Chile on 6 Feb 2020 reminded me of seeing Laughing Gulls on the beaches of the east coast of the USA.

Southern Oceans Cruise - The Kelp Gulls

Well you'd think after being back seven weeks from a trip I would have more Blog postings from said trip. I did have 8500 photos to sort through.  The main excuse for being blogless is not knowing where to start so I'll start with a subject I like. The Gulls. The purpose of the cruise 25 Jan to 6  Feb 2020 from Buenos Aries, Argentina to Santiago, Chile was mainly for the seabirds and an opportunity to see some of the Antarctic.  Any gulls were gravy.    

Gull diversity was actually low with only five species on the trip. Only Kelp Gull was widespread and common. Dolphin Gull and Brown-hooded Gull were numerous within their range. On the last day of the trip at San Antonio, Chile (near Santiago) there were plenty of wintering Franklin's Gulls and a few of the beautiful Gray Gull. Kelp Gull was the gull of most interest. It is a bird we need to know in Newfoundland. An adult kelp Gull did happen in St. John's 23 & 25 December 2016  [see the posting with pictures here  http://brucemactavish1.blogspot.com/2016/. ]It could happen again. First impressions were about Herring Gull size and identical in behavior. Darker black than Great Black-backed Gull. A broad white trailing edge to secondaries while not as obvious as Slaty-backed Gull was still easily noticeable among our local gulls.  The legs were greenish, sometimes with a yellowish tinge.  

What follows is a series of pictures that I wish I had for reference back in 2016.

Note those greenish legs. This was typical leg colour of the Kelp Gulls that I saw during the period of observation late Jan/early Feb. Descriptions/photos of Kelp Gull usually say/show the legs are yellowish with a greenish tint.  I think this probably true during height of breeding display in spring and early breeding season. I was present at the end of the nesting season. Chicks were large in the nests and in San Antonio, Chile there were many recently fledged juveniles. The St. John's, Newfoundland Kelp Gull had dull greenish legs in late December which should have been height of breeding season for Kelp Gulls in the Southern Hemisphere. However, the St. John's bird was still growing P10 indicating it had adjusted to the Northern Hemisphere seasons and was going into winter plumage. photo:  1 Feb 2020, Ushuaia, Argentina


The dump at Ushuaia, Argentina, Cape Horn is the most southern dump in the world and about ten minutes via taxi from the dock in case you are ever there. Not the first destination for the average traveler.  While Richard Crossley and I were there on foot the dump operators and dump dog allowed us in no problem but motioned for us to stand off to the side. No English.  Views were pretty good but short of ideal

Punta Arenas, Chile on 2 Feb 2020

The following pictures are all from Punta Arenas Chile in the southern tip of the country (not far from Ushuaia, Argentina!).

 The colour of those Feet!! Stamp of approval for Kelp Gull.



The reddish orbital ring and shaded olive-coloured  iris were typical of the Kelp Gulls at this southern latitude. 




 The feet and legs were looking more yellowish on the bird above and below that were only 50 m apart but did not seem to be a pair. 


This bird was one of maybe two I saw with a mirror on P9. it was in fact photographed on The Falkland Island on 25 Jan 2020.



I have a few juvenile Kelp Gull photos from San Antonio, Chile that I was going to add to this post but I seem to have met the limit for number of photos.  The end of the day update on C-19 makes me wonder when the next time mankind will even care about the identification of Kelp Gull. 

 Birders will carry on after the crumbling of civilization as we know it now. The     genes have been sown.
