Why is the House Sparrow disappearing from our cities? 🐦🏘️ Our new research in Spain reveals a worrying trend: annual survival is declining, with adult females and juveniles hit the hardest. A thread on the survival of our iconic urban neighbor. 🧵👇 doi.org/10.25225/jvb.2…

We tracked an urban population in eastern Spain (2017-2020) using color-marking and CJS models. Of 198 sparrows, we resighted 74%. The goal? To map how seasonality and urban life impact their year-to-year survival in a Mediterranean city. 📊📈 #UrbanEcology #Ornithology

Modern cities are getting tougher: 🚫 Fewer nesting sites 🍔 Low food quality 🌫️ High pollution Robust data on survival and productivity are essential to assess the long-term trends of the species across Europe. 🏙️🐦

NEW in #JvertBiol Surviving in the city: annual and seasonal survival variation in Mediterranean house sparrows Passer domesticus doi.org/10.25225/jvb.2… @BioOneNews| @CzechAcademy| @JVertebrBiol|@edberpon|#ornithology

Interesting patterns emerged: • Redwings had significantly more plastics than Song Thrushes • Juveniles > adults in microplastic loads Our results show thrushes can act as indicators of terrestrial microplastic pollution, even in wintering areas. @UEuropea @UEuropeaPrensa

We analysed digestive tracts of: 🐦 Song Thrush (Turdus philomelos) 🐦 Redwing (Turdus iliacus) From 32 birds we recovered 326 microplastics. Most particles were: 🔹 fibres (44%) 🔹 films (36%) 🔹 fragments (20%) Blue, red, and black plastics dominated.

🥤Plastic pollution is everywhere... even in terrestrial birds🐦 In our new study from Mediterranean olive orchards in Spain, we found microplastics in 100% of wintering thrushes examined. 🧵👇 📄: link.springer.com/article/10.100… #Microplastics #PlasticPollution #Ornithology

We highlight key knowledge gaps and call for coordinated, large-scale monitoring to better understand the future of this iconic species. Read the full open-access article: museucienciesjournals.cat/en/abc/issue/4… #sciencenews #birdsworld

🔍 What we found: • 114 peer-reviewed studies since the 1980s • Research heavily focused on health, biology & behaviour • Very little work on conservation • Major geographic gaps • Urbanization, changing agriculture, and human activity shape sparrow trends 🔑Keywords
