We realease AVONICHE, a global dataset with detailed information on the proportional use of 32 foraging niches, combining dietary categories with the behaviours and substrates used to access resources.

For a seed to be dispersed during a migratory flight, the 🍒 must be eaten close to sunset, since thrushes migrate at night. That is feasible according to ingestion times. Moreover, data from our feeding experiments in captivity indicate that a song thrush can eat up to 113 fruits/day (mean 54)!

📢 NEW PAPER OUT!

Excited to share our review on Iberian House Sparrows, bringing together decades of research and setting the stage for a more integrated understanding of the species in the region.

Big thanks to all contributors for their dedication & teamwork!

📌 We highlight key knowledge gaps and call for coordinated, large-scale monitoring to better understand the future of this iconic species.

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

🔑Keywords

Despite being one of the most familiar birds in our towns and farmlands, and one of the most studied worldwide, no integrative synthesis existed for Iberia… until now.

📢 Thrilled to share our new paper 🌍

We found synthetic debris in nearly 1/4 of Eurasian otter spraints examined across five European countries, revealing how plastics infiltrate freshwater ecosystems.
