Robert Flood ( St Mary’s, Isles of Scilly, UK) has published in the 2104 issue of Seabird, the annual journal of the Seabird Group, on moult patterns of immature Black-browed Albatross  Thalassarche melanophris based on “hundreds” of photographs of  birds taken at sea.

Chris Perrins (Edward Grey Institute of Field Ornithology, University of Oxford, UK) has published in the 2104 issue of Seabird, the annual journal of the Seabird Group, on survival of Manx Shearwaters Puffinus puffinus banded as fledglings in the 1960s and 1970 on an island off Wales.

The paper’s abstract follows:

During an 11-year period starting in the mid-1960s, large numbers of fledgling Manx Shearwaters Puffinus puffinus were ringed and recaptured on Skokholm Island, Pembrokeshire, Wales.  Since it is unlikely that any more will ever be found, this paper summarises the factors that affected the chances of a fledgling surviving long enough to be recaptured on the island.  Both the date on which they were ringed and their weight at that time influenced the probability that they would be recaptured.  Some implications for the annual cycle are discussed.

Jacopo Cecere (ISPRA - Institute for Environmental Protection and Research, Ozzano dell ’Emilia, Italy) and colleagues have published in the journal Ibis on the foraging habitat preferences of Scopoli’s Shearwaters Calonectris diomedea in the Mediterranean Sea.

The paper’s abstract follows:

“The distribution of seabirds at sea is influenced by physical, ecological and anthropogenic factors such as sea depth, prey distribution, intra-specific competition and commerical [sic] fishing activities.  We quantified the foraging habitat preferences of Scopoli’s Shearwater Calonectris diomedea in the Mediterranean Sea. We analysed habitat preferences in relation to a suite of physical and ecological variables including sea depth, net primary production and distance to other colonies (as a proxy of intra-specific competition).  Since the Mediterranean is heavily impacted by commercial fisheries, we also incorporated the distance to fishing harbours in our analyses as a proxy of the availability of discards which are a potential feeding source for Scopoli’s Shearwater.  Foraging birds preferred shallower waters and avoided areas close to other colonies, thereby reducing interactions with conspecifics.  We also found that long-distance trips were undertaken to areas close to fishing harbours, suggesting that these represented particularly profitable locations to compensate for the greater travelling costs involved.  No differences in foraging between the sexes were recorded.  This study improves our understanding of the at-sea distribution and habitat preference of a seabird inhabiting the over-exploited Mediterranean Sea.  Our results support growing evidence that seabirds exhibit complex relationships with commerical fishing activities, which must be considered when planning conservation programmes.”

Kaloakulua must now be pretty famous.  The offspring of Kaluahine and Kaluakane, a pair of Laysan Albatrosses Phoebastria immutabilis on the north-east shore of the USA’s Kauai Island, its growth from hatching to fledging was livestreamed for 148 days last year to thousands of online viewers by a “trosscam” operated by the Cornell Laboratory of Ornithology.

Seen the movie, now read the book!

Susan Dierker, a resident of Kauai, has written an account for children of Kaloakulua’s first year of life as a chick.  The hard-cover book of 44 pages is made up Susan’s evocative paintings of special scenes captured by the remote camera.  These include Kaloakualua (designated to be a female) being visited by a rooster called George, checking out some passing egrets and meeting up with Mango, another Laysan chick from a nearby nest.  At the end of the book the chick successfully fledges and flies out to sea.

Having brought up a daughter who had books read to her nightly until she could read them herself, I can classify children’s picture books into three types.  First, books with just illustrations for very young children, then those with a simple text for each picture so you can allow the child to see and follow the words you are reading out, then for older children those books where you can help them spell out the text themselves.  I place Susan Dierker’s nicely printed and bound book in between the second and third categories.  In fact, I wish I had it two decades back to read out at bedtime.

The short sentences accompanying each painting are all in large capitals and many of the words used come with their Hawaiian versions (for example a Laysan Albatross is a Mōlī and a chicken is a Moa).

The DVD has 10 clips from the livestreaming camera that well complement the book, including KK’s interaction with George.  All in all the book and DVD make a nice package to help persuade your offspring that albatrosses are seriously cool.

Kauai’s trosscam is back in operation again this year, following two nests that are hatching right now (click here); another book, Susan?
