Gull: Kelp (Cape Gull)

Unread postby francoisd » Thu Sep 07, 2006 3:52 pm

Cape Gull (Larus vetula)

Image

This bird used to be called Cape Kelp Gull but is seems that it was split into Cape Gull and Kelp Gull.

This from the website of the Avian Demography Unit

The taxon of "Kelp Gull" which occurs along southern African coastline was, until recently, treated as the subspecies Larus dominicanus vetula. This taxon has now been recognized as a good species with scientific names Larus vetula. The proposed English name is Cape Gull. The iris of dominicanus is pale grey or pale yellow, whereas vetula has a dark brown iris. The taxon vetula is on average larger than dominicanus, and vetula also has a more domed skull.

You will find them in most of the coastal parks

Would say it's a Cape Gull as the picture of a Kelp Gull in SASOL shows a clear pale (whitish) eye.

As to Kelp Gulls in RSA the following again from the ADU website:

There are two records of the nominate Kelp Gull on the continent of Africa. The first was made on 23 October 1982, when a dying bird was found near Yzerfontein, Western Cape. The second record, made on 26 October 1985, was also made near Yzerfontein. These birds were found during the monthly patrols for beached seabirds coordinated since 1978 by Dr Graham Avery of the South African Museum, Cape Town. Both birds were preserved as osteological specimens, and are in the collection of the South African Museum, Cape Town.

Roberts VII now refers to these species only as Kelp Gull (R313), with the scientific name of Larus dominicanus (dominicanus = the pied plumage which resembles the traditional habits of the Dominicans).

Then, the species is broken down into two subspecies:
- dominicanus vetula, our common resident variety, occuring extensively in the Southern Hemisphere, including coasts of Peru, Chile, Argentina, southern Brasil, Antarctic Peninsula, subantarctic islands, New Zealand, Australia, Madagascar and throughout the coast of southern Africa. This is the variation that SASOL Third Edition calls Cape Gull Larus vetula.
- dominicanus judithae, which SASOL refers to as Kelp Gull Larus dominicanus, the very rare variation with the neat, rounded head, vermillion eye ring and the pale ivory to yellow eye during breeding season.

After posting this message on Cape Gull and reading in SASOL that the Kelp Gull has a whitish eye, I noticed that the gull posted by HoepHoep in her "Tsitsikamma 2006" trip report displayed a light eye. I emailed the photo to a friend of mine to see if he could maybe positively ID it as a Kelp Gull.

It does however not seem to be as easy as looking for an pale eye.

He sent me this photo of a "Cape Gull" showing a pale eye and also included some text by Trevor Hardeker that appeared on SABirdNet a couple of years ago.

Text by Trevor Hardeker
Larus d. dominicanus (nominate Kelp Gull) occurs in Australasia, South America, Antarctica and on most of the subantartic islands. Larus d. vetula (aka Cape Gull) is an endemic subspecies (currently considered for full specific status) to Southern Africa. Most books dealing with seabirds cover both of these as subspecies at least. Nominate Kelp Gull also occurs as a vagrant in Southern Africa, with recent records coming from the west coast near Cape Town and the Eastern Cape.

Superficially, differences are that Kelp Gull has a pale eye (beware that some Cape Gulls can show this feature, but Kelp Gull's eye is generally smaller), a smaller more rounded head and a slighter bill. Other suggested differences, although not cast in stone yet as far as I am aware, are that Kelp Gull has a narrower white tip to the tertials and slightly more yellower legs.

Peter Ryan wrote an article on these two gulls in AB&B about a year ago (I can't remember the issue number) and the latest issue of Birding World (one of the top U.K. birding magazines) has a detailed article on the identification of "Kelp" Gulls covering both dominicanus and vetula.

As far as web resources go, try the excellent "Gull Identification Website" which covers the ID's of all the world's gulls in some detail. This site is very useful for all gull watchers and for learning more about the possible gulls that could still occur in SA. Martin Reid's gull website is also well worth a visit, if you are interested in finding out more about gulls. Both these sites have lots of photos.

Some images of the Cape Gull in flight. The white trailing edge on the wing is reputedly narrower in the Kelp and lesser black-backed gulls. The second bird is of a juvenile Cape gull.

Both Kelp (vagrant) and lesser black-backed (uncommon visitor) gulls have the light eye.
