  3. Do Cory’s Shearwaters Calonectris borealis choose mates based on size?

    Nava, Cristina P.; Kim, Sin-Yeon; Magalhães, Maria C.; Neves, Verónica C.
    Many bird species rely on visual cues for mate choice, including those provided by body size or by the size of a body appendage. Mate choice based on size may lead to size-assortative mating, which may in turn have consequences for reproductive performance. In this study, we examined whether body size influences mate choice decisions of Cory’s Shearwater Calonectris borealis, a seabird with nocturnal activity on land. We found evidence of negative assortative mating for bill morphology (nostril height and bill length), but found no assortative mating according to body mass, tarsus length, and wing length. In addition, we investigated...

  5. The role of Malcolm Clarke (1930–2013) in the Azores as a scientist and educationist

    Gomes-Pereira, José N.; Prieto, Rui; Neves, Verónica C.; Xavier, J.; Pham, Christopher K.; Gonçalves, João M.; Porteiro, Filipe M.; Santos, Ricardo S.; Martins, Helen R.
    Malcolm Roy Clarke (1930–2013) was a British teuthologist who made an important contribution to marine science in the Azores archipelago (Portugal). Malcolm started doing research in the Azores from 1980s onward, settling for residency in 2000 after retirement (in 1987). He kept publishing on Azorean cephalopods collaborating in 20% of the peer reviewed works focus- ing on two main areas: dietary studies; and the ecology of cephalopods on seamounts. Since his first visit in 1981, he was involved in the description of the dietary ecology of several cetaceans, seabirds, and large pelagic and deep-water fish. Using his own data, Malcolm...

  9. Painho-de-Monteiro : uma nova espécie de uma velha ave

    Neves, Verónica C.
    […]. O nome científico do Paínho-da-Madeira é “Oceanodroma castro” e o nome científico da nova espécie agora descrita é “Oceanodroma monteiroi” ou Paínho-de Montteiro. As designações vernacular – “de Monteiro” – e científica – “monteiroi” – perpetuarão assim a memória do investigador Luís Rocha Monteiro que tanto contribuiu para a descoberta e conservação desta espécie.

  13. Os pioneiros da ornitologia marinha nos Açores

    Neves, Verónica C.
    Este artigo é composto por três secções e tem por objectivo ilustrar diferentes aspectos da ornitologia marinha nos Açores. A primeira parte realça a importância das crónicas de Gaspar Frutuoso para o conhecimento da comunidade de aves marinhas nos primórdios do povoamento das ilhas e faz referência aos principais naturalistas açorianos, expedições científicas e ornitólogos estrangeiros, que ao longo dos séculos contribuíram para o estudo e conhecimento das aves marinhas dos Açores.

  15. Migration routes and non-breeding areas of Common Terns (Sterna hirundo) from the Azores

    Neves, Verónica C.; Nava, Cristina P.; Cormons, Matt; Bremer, Esteban; Castresana, Gabriel; Lima, Pedro; Junior, Severino M. Azevedo; Phillips, Richard A.; Magalhães, Maria C.; Santos, Ricardo S.
    We describe the migration routes and non-breeding areas of Common Terns (Sterna hirundo) from the Azores Archipelago, based on ringing (banding) recoveries and tracking of three birds using geolocators. Over 20 years, there have been 55 transatlantic recoveries of Common Terns from the Azores population: six from Argentina and 49 from Brazil. The three tracked birds migrated south in different months (August, September, November), but the northern migration was more synchronous, with all leaving in April. The birds were tracked to three areas of the South American coast: the male spent November—April on the northern Brazilian coast (13°N–2°S), whereas the...

  17. Leapfrog migration and habitat preferences of a small oceanic seabird, Bulwer's petrel (Bulweria bulwerii)

    Ramos, Raül; Sanz, Víctor; Militão, Teresa; Bried, Joël; Neves, Verónica C.; Biscoito, Manuel; Phillips, Richard A.; Zino, Francis; González-Solís, Jacob
    AIM: Our current understanding of migratory strategies and the reasons for their high variability along the phylogenetic tree remains relatively poor. Most of the hypotheses relating to migration have been formulated for terrestrial taxa; classically, oceanic migrations were considered as merely dispersive because of the scarcity of observations in the open ocean. We describe for the first time, the migration strategy of a small seabird, the Bulwer's petrel (Bulweria bulwerii), and provide new insights into the ecology and evolution of long-distance marine migrations. LOCATION: Subtropical and tropical Atlantic Ocean. METHODS: Using cutting-edge geolocators, we examined the year-round distribution and at-sea activity patterns...
