Abstract:
A new feather mite species of the genus Microspalax Mégnin & Trouessart, 1884 (Alloptidae: Microspalacinae) is described from the Atlantic petrel, Pterodroma incerta (Schlegel, 1863), in Brazil. Males of M. atlanticus sp. nov. differ from M. pterodromae Dubinin, 1949 mostly by the wider opisthogastric shields and setae ps3 inserted at posterior third of that shield. This is the first representative of the genus described from Brazil, and the first feather mite described from a procellariiform bird in the country. A key to males of Microspalax species is presented.

Abstract: Coastal sea surveys off eastern Guadeloupe, French West Indies, in 2001–2008 showed the presence of Black-capped Petrel (Pterodroma hasitata). The species occurs in small numbers from October to March, peaking from November to January. Such a seasonal appearance coincides with the species’ breeding calendar, suggesting that these birds may belong to the small breeding population recently rediscovered in nearby Dominica. The presence of this rare and endangered species in French waters off Guadeloupe has to be taken into account in national conservation policy. Keywords: at-sea records, Black-capped Petrel, Dominica, Guadeloupe, Pterodroma hasitata Resumen: Diablotín (Pterodroma hasitata) occurencia cerca Guadalupe, Antillas Menores, 2001–2008—Encuestas en el mar costero del este de Guadalupe, en las Antillas francesas en 2001–2008 han mostrado la presencia del Diablotín (Pterodroma hasitata). La especie ocurre en pequeños números de octubre a marzo, alcanzando un máximo de individuos entre noviembre y enero. Tal aparición estacional coincide con el calendario reproductivo de la especie, lo cual sugiere que estas aves pueden pertenecer a la pequeña población reproductora recientemente redescubierta en la cercana Dominica. La presencia de esta especie rara y en peligro de extinción en las aguas francesas frente a Guadalupe debe tenerse en cuenta en la política nacional de conservación.

Resumimos información publicada, de especímenes de museo y nuestras propias observaciones en Rapa Nui. Dentro de la información mas relevante incluye el primer registro documentado para el Petrel de Murphy (Pterodroma ultima), Petrel Gigante Subantártico, (Macronectes halli), Albatros de Ceja Negra (Tha-lassarche melanophrys) y Petrel de Fénix (Pterodroma alba), segundo registro documentado para el Ave del Trópico Cola Blanca (Phaethon lepturus). Adicionalmente documentamos el primer registro de nidificación para el país para el Petrel de Henderson (Pterodroma atrata), Petrel de Murphy (Pterodroma ultima), y Petrel de Fénix (Pterodroma alba). Se han registrado un total de 19 especies de aves marinas para Rapa Nui, 13 nidificando y 6 visitantes. Aunque dos de los visitantes (Fregata minor y Onychoprion lunatus) posiblemen-te nidificaron en el pasado pero al menos no lo han hecho en los últimos 100 años. Doce especies te-rrestres han sido introducidas y hoy en día solo 8 sobreviven y otras 6 han sido encontradas en el regis-tro arqueológico todas extintas. El número de especies registradas en Rapa Nui es de 53 más 4 hipotéti-cas, incluyendo las encontradas en sitios arqueológicas. En el registro arqueológico Steadman (1995) consideró 29 especies, (incluyendo las extintas) pero dos de las que el estimó como extirpadas se en-contraron y nidificando en la isla. Muchas de las especies mencionadas por Steadman (1995) como ex-tirpadas es posible que habiten allí por ser migrantes australes y nidificantes en áreas subantarticas. Entre otoño y primavera son las épocas que han sido menos visitadas por ornitólogos.

Abstract:
I describe and illustrate five new species of chewing lice in the genus Halipeurus, parasitic on petrels from the Pacific and the Atlantic Oceans. They are: Halipeurus confusus n. sp. from Pterodroma nigripennis; H. pricei n. sp. from Pterodroma brevipes and Pt. leucoptera; H. atlanticus n. sp. from Pterodroma cahow and Pt. madeira; H. pelagodromae n. sp. from five subspecies of Pelagodroma marina; and H. vincesmithi n. sp. from Oceanodroma matsudairae. I discuss the morphological similarities of the currently recognised subgenera of Halipeurus and propose to synonymise them—Synnautes Thompson, 1936 and Anamias Timmermann, 1965—under the nominate subgenus. I propose two new synonymies at species level: Halipeurus sawadai Nakagawa, 1959 and Halipeurus angusticeps fosteri Edwards, 1961 both as junior synonyms of Halipeurus angusticeps (Piaget, 1880). Also, I propose to merge H. subclavus Timmermann, 1961 and Halipeurus spadix Timmermann, 1961 as subspecies of H. spadix. I report several new host-louse records for other Halipeurus species, and present additional information and illustrations for H. raphanus Timmermann, 1961, H. fallacis Timmermann, 1960, H. nesofregettae Timmermann, 1961 and H. spadix subclavus Timmermann, 1961 based on their type material and other specimens. Lectotypes of Lipeurus pelagicus Denny, 1842 and Lipeurus languidus Kellogg & Kuwana, 1902 are designated.

Abstract:
Alexander (1954: 489) recorded a petrel (Aves: Procellariiformes) captured alive on board a ship in the Indian Ocean by Mr W.W.A. Phillips who, after removing some lice, liberated it the following morning. Alexander (1954) identified that petrel as the species “Pterodroma aterrima Bonaparte”, now placed in the genus Pseudobulweria. The lice were kept in the collection of the then British Museum (Natural History), now the Natural History Museum, London, England. Jouanin (1955) published a new species of petrel from the Indian Ocean as Bulweria fallax. Jouanin (1957: 19) discussed the identity of the petrel identified by Alexander (1954) as Pterodroma aterrima, stating that the descriptive data given by Alexander (1954) did not clearly fit either P. aterrima or B. fallax. However, considering the geographical coordinates where the bird was captured, Jouanin (1957) believed it was more likely Bulweria fallax.

Abstract:
The only population of Gould's Petrel Pterodroma leucoptera leucoptera has declined substantially during the last few decades. Adult mortality has been high, and has exceeded potential recruitment. Breeding success has been low. Entanglement in the sticky fruits of the Birdlime Tree Pisonia umbellifera and predation by Pied Currawongs Strepera graculina and Australian Ravens Corvus coronoides have been the major causes of petrel mortality on land. Experimental management actions aimed at ameliorating these threats were implemented, and their efficacy assessed. The removal of Pisonia and the control of avian predators dramatically lessened the mortality of Gould's Petrels ashore on Cabbage Tree Island. Instigation of these management actions in 1993 was coincident with a 68% rise in the number of birds brooding eggs in mid-December. Further small increases in the breeding population occurred in subsequent years. Management of the colony was also coincident with a substantial increase in breeding success (up from 25% to 45%). Breeding success increased to 59% in the 1994?95 season, but declined to 26% during 1995?96. Prior to management of the colony, an average of 30 birds fledged per annum (range 23?40; n= 4); after management, this rose to 167 per annum (range 105?233; n= 3). Management of the colony appears the most likely cause of this turnaround, but the possibility of it being due to extraneous factors such as weather or oceanographic perturbations cannot be excluded. The threats posed by Pisonia umbellifera and avian predators were, together, sufficient to account for the decline of Gould's Petrel. The demonstration that these two threatening processes can be ameliorated successfully suggests a high potential for recovery of the species.

Abstract:
Albatrosses and petrels (Order Procellariiformes) are renowned for the huge distances they can cover at sea, and since the advent of tracking technology their pelagic lifestyles are generally well studied. However, tropical species are under-represented in the literature, and may be particularly flexible in their behaviour since tropical oceans are oligotrophic and prey availability is often patchily distributed. Round Island petrels breed in such an environment off the coast of Mauritius in the south-western Indian Ocean. Whilst originally identified as Trindade petrels (Pteromdroma arminjoniana), it has recently been revealed that this population is in fact a mixed, hybridizing population with at least two additional species, namely the Kermadec and Herald petrels (P. neglecta and P. heraldica). However, to date no research has been conducted on the colony-based at-sea distribution of these petrels, or how their mixed ancestry may influence their distribution at sea. In this thesis I firstly explore the possibility that Round Island may not be the only point of contact between these species and find that migration and introgression between wide-ranging Pterodroma may be more common than previously thought. I go on to develop a novel data cleaning method to enable the analysis of geolocation data from Round Island petrels, and use that data to describe for the first time their at-sea distribution and the extensive within-population variation in these patterns. Finally, I use a combination of tracking and microsatellite genotype data to ultimately weigh the influence of individual genetic background and the wider seasonal environment on distribution variability around the breeding colony. The Round Island petrel population is a stronghold where seabird populations globally are in decline. This thesis adds to the limited literature on ecology of tropical petrel species, and highlights the importance of considering behavioural and genetic diversity in future conservation plans.

Abstract:
Réunion is the only tropical island that supports two endemic gadfly petrels. Population modelling has indicated that the current threats to the Barau’s Petrel (Pterodroma baraui) may drive it to extinction; this fate is almost definite for the Mascarene Petrel (Pseudobulweria aterrima). Management interventions have therefore been implemented, but conservation potential is handicapped since virtually nothing is known about the former species’ at-sea biology. Thus, following numerous recommendations, this study aimed to combine stomach content, stable isotope, and fatty acid analyses so to provide new information on the at-sea ecology of Barau’s Petrel. Breeding colonies were repeatedly visited over the same season and samples gathered from adults, fledglings, and downy chicks. Stomach contents consisted mostly of accumulated cephalopod beaks whereas structures from fishes, molluscs, arthropods, and crustaceans were less frequently encountered. Fatty acid profiles of blood varied greatly among individuals and the lowincidences of monounsaturated and n-3 fatty acids discounted fish as an important dietary component. δ¹⁵N of blood indicated a niche between the fourth and fifth trophic levels, which proposes that these birds scavenge to a greater degree than other sympatric seabirds and suggests that adults are also reliant on their endogenous reserves during breeding. δ¹³C values confirmed the migratory behaviour of adults since birds returning from the non-breeding grounds were enriched relative to individuals sampled through the breeding period. Significant intra-breeding season variations in δ13C were also observed, which matched this species’ patterns of habitat use as have recently described. These results collectively indicate an opportunistic behaviour, which implies some degree of resilience against shifts in prey availability/accessibility, and suggest that this species’ reproduction isdependent on distant foraging areas. This breeding strategy is synonymous with great vulnerability as over-investing into a single breeding episode may jeopardize future survival and fecundity. Thus, in light of environmental conditions that are becoming increasingly more susceptible to dramatic changes, the birds could rather be prioritising adult survival, over reproductive output. Further work is obviously necessary and should benefit from databases of fatty acid profiles and isotope signatures of potential prey species.

Dissertação de Mestrado em Ecologia apresentada à Faculdade de Ciências e Tecnologia
Os procellariiformes são aves marinhas predadoras, quase exclusivamente pelágicas, que em algumas espécies exibem atividade predominantemente noturna na alimentação e na procura de presas (atividade no mar). O principal objetivo desta tese foi investigar o efeito da lua em três aves procellariiformes de diferentes tamanhos - cagarra, Calonectris borealis, freira-do-bugio, Pterodroma deserta e o pintaínho, Puffinus baroli, que se reproduzem na Ilha das Berlengas (Portugal), Ilha do Bugio (Arquipélago da Madeira) e Ilhéu de Cima e Selvagem Grande (arquipélago da Madeira), respetivamente, durante os anos de 2007-2017. Foram colocados no tarso destas aves, dispositivos Global Location Sensing (GLS). Estes dispositivos permitem saber a localização e obter dados sobre a atividade, sobre a forma de luminosidade e salinidade, das aves. Posteriormente, os dados de atividade foram filtrados de forma a permitir analisar a atividade noturna dos indivíduos durante seus períodos de reprodução e fora da reprodução. Os dados obtidos foram então utilizados para investigar o efeito da lua (lua cheia, nova e quartos) no (1) comportamento no mar, (2) nas visitas a colónia durante a época de reprodução e (3) nos movimentos migratórios.Globalmente, os nossos resultados indicam que a lua influenciou essas aves marinhas nos três comportamentos descritos anteriormente. Sob períodos de lua cheia as espécies de pequeno porte, a freira-do-bugio e o pintaínho, aumentaram a sua atividade no mar (por exemplo, mais tempo gasto a voar), procuraram alimento em zonas mais pelágicas, de alta profundidade e com mais vento, e também diminuíram o numero de visitas à colónia quando comparados com um procellariiforme de maior porte (cagarra). A Lua cheia também ditou um maior número de partidas em migrações pré- e pós- época de reprodução para os migrantes transequatoriais (cagarra e freira-do-bugio), mas não para a espécie residente (pintaínho).
Procellariiforms are almost exclusively pelagic marine predators, with some species exhibiting a predominately nocturnal foraging activity. The main objective of this thesis was to investigate the effect of the moonlight on three different sized procellariiform seabirds - Cory’s Shearwater, Calonectris borealis, Deserta Petrel, Pterodroma deserta and Macaronesian shearwaters, Puffinus baroli, breeding at Berlenga Island (mainland Portugal), Bugio (Madeira archipelago) and Cima and Selvagem Grande Islets (Madeira archipelago), respectively, during the breeding seasons of 2007-2017. Global Location Sensing (GLS) devices were mounted on the birds’ tarsus and location and activity data was then filtered to analyse the nocturnal foraging activity of the individuals during their breeding and non-breeding periods. Such individual tracking data was then used to investigate the effect of moonlight (full and new moon and quarters) on the (1) at-sea behaviour, (2) colony attendance while breeding and (3) migratory schedule.Overall our results indicate that the moon influenced these seabirds in the former three behaviours. Under full moonlight small sized procellariiforms (Macaronesian shearwaters and Desertas petrels) increased their at sea activity (e.g. more time spent flying), foraged in more pelagic, high depth and windier domains, decreased their colony attendance when compared to a larger sized procellariform (Cory’s shearwater). Full moon also dictated a higher number of departures in pre- and post-breeding migrations for the transequatorial migrants (Cory’s shearwaters and Desertas petrels) but not for the resident species (Macaronesian shearwater).
