Creating an olfactory trap: do procellariiform seabirds sniff out plastics at sea?

Matthew Savoca (Department of Neurobiology, Physiology, and Behavior, University of California, Davis, USA) and colleagues have published on-line and open access in the journal Science Advances on whether procellariform seabirds are attracted to plastic debris at sea by smell as well as by sight.

The paper’s abstract follows:

“Plastic debris is ingested by hundreds of species of organisms, from zooplankton to baleen whales, but how such a diversity of consumers can mistake plastic for their natural prey is largely unknown.   The sensory mechanisms underlying plastic detection and consumption have rarely been examined within the context of sensory signals driving marine food web dynamics.  We demonstrate experimentally that marine-seasoned microplastics produce a dimethyl sulfide (DMS) signature that is also a keystone odorant for natural trophic interactions.  We further demonstrate a positive relationship between DMS responsiveness and plastic ingestion frequency using procellariiform seabirds as a model taxonomic group.  Together, these results suggest that plastic debris emits the scent of a marine infochemical, creating an olfactory trap for susceptible marine wildlife.”

Volunteer with threatened shearwaters in the Med: BirdLife Malta is looking for help

BirdLife Malta is looking for a voluntary assistant to join its international seabird team in the Maltese Islands.

The volunteer will assist in ongoing monitoring and research activities with two ACAP potential candidate species, the Yelkouan Puffinus yelkouan and the Scopoli's Calonectris diomedea Shearwaters and on the Mediterranean Storm Petrel Hydrobates pelagicus melitensis.

Volunteer assistants will be based in BirdLife Malta’s offices and in Natura 2000 sites.  Accommodation and allowances will be provided.

Moult patterns and carryover effects in albatrosses and petrels: an MSc opportunity in South Africa

Applications are invited from previously disadvantaged South African citizens for the above full-time MSc research scholarship at the University of Cape Town’s Percy FitzPatrick Institute, a world-renowned, national Centre of Excellence (CoE) in ornithological research with a strong emphasis on postgraduate studies (click here).

The successful applicant will focus on understanding how breeding performance interacts with the extent of moult in large procellariiform seabirds.  The candidate will be supported and supervised by the Fitztitute’s Director, Peter Ryan.

Moult is one of the major annual constraints faced by birds, and large birds in particular struggle to accommodate moult in their annual cycle because the rate of feather growth scales only weakly with body size. This creates an evolutionary dilemma for large procellariiform seabirds such as albatrosses and giant petrels which either have to overlap moulting with breeding, potentially compromising their ability to breed successfully, or only replace a subset of feathers each year, potentially leading to an accumulation of old feathers.  This conflict might lead to trade-offs between breeding and moulting, which have been inferred for North Pacific albatrosses, but not fully explored in Southern Ocean species.  In addition, most focus to date has been on primary moult patterns in these birds, but they have many more secondaries than primaries, and their strategies to replace their secondaries also warrant investigating.  The successful candidate will use photographic records of moult status of breeding albatrosses and giant petrels from Marion and Gough Islands to address these questions.”

The closing date for applications is 30 November 2016.  Read more here.

Were albatrosses smaller in the past? A new ancestral form from Antarctica

Carolina Hospitaleche (CONICET, La Plata, Argentina) and Javier Gelfo have published in the journal Historical Biology on an old bird bone from Antarctica.

The paper’s abstract follows:

“New remains from the La Meseta (Thanetian – Lutetian) and Submeseta (Lutetian – Rupelian) formations (Seymour Island, Antarctica) are tentatively assigned to Diomedeidae and Procellariidae (Procellariiformes).  Based on the fossil record and several analyses that attempt to explain the evolutionary patterns of Diomedeidae, Notoleptos giglii gen. et sp. nov., based on a small tarsometatarsus, was an ancestral form that lived in Antarctica before the rise of large-sized albatrosses.  Subsequent environmental cooling since the late Oligocene could have selected against small body size, to the detriment of small-sized albatrosses like Notoleptos, thus favoring large body size and setting the stage for the development of the specialized albatross flight.”

A new breeding season commences with a webcam again for the Northern Royal Albatrosses at Taiaroa Head

With 80 or so individually colour-banded Northern Royal Albatrosses Diomedea sanfordi recorded back in their mainland breeding colony at New Zealand’s Taiaroa Head, the first five eggs of the season had been laid up to yesterday (and eight by today).  One of the returned adults is Toroa, the 500th chick to hatch on Taiaroa Head, in 2007.

The webcam that followed the fortunes to fledging of chick Moana (Maori for sea) last season has now been set up to overlook a new younger pair (colour bands Blue Black (BK) for the 12-year old fostered male and Red Blue Black (RBK) for the 14-year old female) for the current breeding season.  Both birds nested for their first time together during the 2011/12 season, when they fledged their first chick.  “The 2012/13 season was their 'year off' and they spent that time apart and at sea before coming back to attempt to breed in the 2013/14 season.  They were not successful that season as their egg was infertile, so they left and later returned to breed in the 2014/15 season.  They were successful this time round, fledging their second chick. After another year off at sea during the 2015/16 season, they are now back to attempt to breed again for this 2016/17 season” (click here).

Live streaming from the "royalcam" can now be watched here.

The Royal Albatross Centre at Taiaroa Head reported recently via Facebook:

“No egg at our webcam nest yet, but viewers got to witness mating yesterday [4 November], so if this was the mating that leads to a fertile egg, then it won't be laid for about another two weeks (but note that they do mate often over this period and last night's mating may not have been the first for this pair this season.  Either way it will be at least six days after the egg is laid before we can confirm if the egg is actually fertile - done by candling, that is shining a torch through it to look for blood vessels of a developing embryo).”

Around 26 chicks from the previous breeding season have now fledged.
