Birds in education: innovative learning methods for capacity building in nature...
Roque, Inês; Godinho, Carlos; Rabaça, João E.; van der Horst, Shirley; Klein, Akos; Schneider, Zoltan; Patko, Laszlo; Gigler, Dora; Portaccio, AlessiaThe 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 capt...
A First Record of Organochlorine Pesticides in Barn Owls (Tyto alba) from Portu...
Roque, Inês; Lourenço, Rui; Marques, Ana; Martínez-López, Pilar; Espín, Silvia; Gómez-Ramirez, Pilar; García-Fernández, Antonio Juan; Roulin, AlexandreWe evaluated feathers as a non-destructive biomonitoring tool documenting organochlorine pesticides (OCP) in liver and checked possible trends in pesticide use in two areas based on OCP concentrations in barn owls (Tyto alba). We measured the concentrations of 16 OCP in 15 primary feathers and 15 livers from barn owl carcasses collected on roadsides in Tagus Valley and Évora regions, south Portugal. Total OCP m...

Songbirds promote connectivity between riparian galleries and adjacent habitats
Almeida, Ana Patrícia; Gomes, Marisa; Rabaça, João E.; Ramos, Jaime A.Riparian galleries are among the most vulnerable habitats in the world and are well known for their importance to the most specialized riparian bird species. In this study, we analyzed songbird composition, songbird diet, trophic ecology and seed dispersal in riparian galleries and adjacent Montado matrices in southern Portugal to address the importance of birds in promoting the connectivity between riparian ga...
Multispecies lanscape functional connectivity enhances local bird species' dive...
Salgueiro, Pedro A.; Valerio, Francesco; Silva, Carmo; Mira, António; Santos, Sara M.; Rabaça, João E.Local species assemblages are likely the result of habitat and landscape filtering. However, there is still limited knowledge on how landscape functional connectivity complements habitat attributes in mediating local species assemblages in real-world fragmented landscapes. In this study, we set up a non-manipulative experimental design in a standard production forest to demonstrate how functional connectivity d...
Sylvia melanocephala Sardinian Warbler
Herrando, Sergi; Rabaça, João E.; Boyla, Kerem A.The EBBA2 project was carried out by the EBCC network of partner organisations from 48 countries. In total, around 120,000 fieldworkers contributed data to the atlas, the great majority of them on a voluntary basis. As such this project constitutes one of the biggest citizen science projects on biodiversity ever. Data collection and analysis followed a rigorous scientific protocol, led by a team of researchers ...
Foraging in landfills: Feeding behavior of the White Stork (Ciconia ciconia) an...
Rabaça, João E.; Ventura, Tiago; Faria, Nuno; Roque, InêsThe decline of the White Stork (Ciconia ciconia) in the Iberian Peninsula was averted within the last 30 years, partially due to an increase in food availability in landfills. In this study, we compared 2 colonies located at different distances from a landfill in southern Portugal, with the aim of assessing differences in stork diets. We also compared our current results with data from the same colonies before ...
TytoTagus Project: Common Barn Owl post-fledging dispersal and survival in the ...
Roque, Inês Margarida; Marques, Ana; Lourenço, Rui; Godinho, Carlos; Pereira, Pedro; Rabaça, João E.The Tagus Estuary hosts a high concentration of juvenile Common Barn Owls (Tyto alba) during the post-fledging dispersal period with more than 15 owls/km detected along roads in the south floodplain of Vila Franca de Xira (SF). The Tyto Tagus project examined the origin of these birds with six re-sightings of 136 colour-ringed nestlings (2006–2008) and subsequently (2009-2012) with 41 VHF radio-marked juveniles...
Effect of vineyard characteristics on the functional diversity of insectivorous...
Lourenço, Rui; Pereira, Pedro; Oliveira, Amália; Ribeiro-Silva, Joana; Figueiredo, Diogo; Rabaça, João E.; Mira, António; Marques, J. TiagoInsectivorous birds have a large potential to provide biocontrol services in vineyards, thus contributing to the sustainability of this agroecosystem. Bird communities are influenced by vineyard management practices and surrounding landscape, which may influence their role as ecosystem service providers. Functional diversity indices are indicators of bird community composition, and thus may reflect potential bi...
