First national census of the Common Barn-owl (Tyto alba) breeding population in...
Roque, Inês; Lourenço, RuiThe Common Barn-owl (Tyto alba) is a cosmopolitan farmland bird that has disappeared from almost 50% of its range in mainland Portugal in the last decade. In order to improve estimates of the distribution and population abundance of the species, and contribute to understanding its long- term population trend, we carried out the First National Census of the Common Barn-owl Breed- ing Population. The census inclu...
Structured citizen science to unravel the distribution of wintering Short-eared...
Falé, João; Tomé, Ricardo; Lourenço, Rui; Roque, Inês; Leitão, AlexandreCitizen science has proven to be very useful in ornithology, especially for data collection of the distribution of discrete raptors. Short-eared Owls (Asio flammeus) are present in Portugal during winter, where their reduced vocal activity, low density and crepuscular habits hamper detection. Nevertheless, the overall decline of its European populations emphasizes the importance of determining its distribution ...
Censo Nacional de Coruja-das-torres (Tyto alba) 2023: relatório preliminar
Roque, Inês; Lourenço, Rui; Tomé, Ricardo; Leitão, Alexandre; Botelho, Ana; Santos, Carlos; Raposo, Daniel; Santos, Daniel; Realinho, EduardoA coruja-das-torres é uma ave de rapina noturna que apresenta atualmente uma tendência populacional negativa na Península Ibérica (GTAN-SPEA 2022, Escandel & Escudero 2021) e na Europa (BirdLife International 2021, Eionet 2022). Caça preferencialmente em áreas abertas, tais como campos agrícolas, pastagens e florestas pouco densas, evitando florestas densas e grandes extensões de matos. Ocupa também áreas urban...
Relatório do 1.º censo nacional da população nidificante de coruja-das-torres (...
Roque, Inês; Lourenço, Rui; Tomé, Ricardo; Lopes, Alexandra; Alonso, Hany; Botelho, Ana; Leitão, Alexandre; Santos, Carlos; Raposo, DanielA coruja-das-torres é uma ave de rapina noturna que apresenta atualmente uma tendência populacional negativa na Península Ibérica (GTAN-SPEA 2023, Escandell & Escudero 2022) e na Europa (BirdLife International 2021, Eionet 2022), estando classificada como Quase Ameaçada na Lista Vermelha das Aves de Portugal Continental e de Espanha (Almeida et al. 2022, López-Jiménez 2021). Caça preferencialmente em áreas aber...
Citizen science results of GTAN-SPEA: censuses of the short-eared owl (Asio fla...
Lourenço, Rui; Roque, Inês; Falé, João; Tomé, Ricardo; GTAN, SPEAThe Working Group on Nocturnal Birds of SPEA (GTAN-SPEA) promotes since 2010 the monitoring program for nocturnal birds called “Noctua-Portugal”. This citizen-science initiative has allowed population trend estimates to be calculated for the 10 target species. After 13 sampling seasons (2009/10 to 2021/22), the data collected by more than 140 volunteer collaborators in 91 sampling squares points to a strong dec...
Ajude-nos a encontrar a coruja-das-torres
Roque, InêsA coruja-das-torres (com o nome científico Tyto alba) é uma das sete aves de rapina noturnas que existem em Portugal. Podemos encontrá-la em áreas agrícolas, mas também em florestas pouco densas e zonas urbanas. Adaptada a estar próxima de nós, humanos, a coruja-das-torres nidifica muitas vezes em edifícios e o mesmo local pode ser ocupado durante décadas. A coruja-das-torres está a diminuir muito em Portugal, ...
Traditional atlases are out of date? How online platforms can help when the res...
Godinho, Carlos; Pereira F, Pedro; Lourenço, Rui; Roque, Inês; Alonso, Hany; Rabaça, JoãoTime has changed, online portals for biodiversity, and for birds in particular, are widespread and respon- sible for collecting millions of records annually around the world. This has multiple implications on the data availability and quality. On one side we have huge up-to-date datasets to be analysed, but on the other side, concerns about data quality and data standardization are common. Can part of this data...
Birds in education: innovative learning methods for capacity building in nature...
Roque, Inês; Godinho, Carlos; Rabaça, JoãoThe role of volunteer birdwatchers in bird censuses across the world is crucial to acquire data for sci- ence and conservation, and people with different skill specializations and motivations are engaged as citizen scientists. Bird species richness is positively related to life-satisfaction across Europe, while this association doesn’t exist in other wildlife groups. Therefore, birds seem to be particularly cap...
Landscape and Climatic Variations Shaped Secondary Contacts amid Barn Owls of t...
Cumer, Tristan; Machado, Ana Paula; Dumont, Guillaume; Bontzorlos, Vasileios; Ceccherelli, Renato; Lourenço, Rui; Roque, InêsThe combined actions of climatic variations and landscape barriers shape the history of natural populations. When organisms follow their shifting niches, obstacles in the landscape can lead to the splitting of populations, on which evolution will then act independently. When two such populations are reunited, secondary contact occurs in a broad range of admixture patterns, from narrow hybrid zones to the comple...
