Eine neue Studie der Universität Lund belegt, dass Mondlicht für den Zugvogel Rothals-Ziegenmelker von entscheidender Bedeutung ist. Die Nahrungsaufnahme, der Zug und die Brutzeit des Vogels werden vollständig vom Mondzyklus bestimmt. Forscher weisen auf die Anfälligkeit nachtaktiver Tiere gegenüber Veränderungen der Lichtverhältnisse hin.

An unusual outbreak of blue tit disease has struck small birds in southern and central Sweden since March. Hundreds of reports of dead birds have reached Statens veterinärmedicinska anstalt (SVA). Deputy state veterinarian Karin Olofsson-Sannö describes it as an outbreak never before seen in the country.
Researchers at the University of Cincinnati have found that monk parakeets approach unfamiliar birds cautiously, gradually building trust to avoid aggression. The study, published in Biology Letters, reveals patterns similar to human social interactions and other animals. This cautious behavior helps the birds form strong, beneficial bonds over time.

A new study reveals that five key forests in Central America provide vital wintering and stopover habitats for numerous migratory bird species from North America. These forests shelter significant portions of global populations for birds like Wood Thrushes and Cerulean Warblers, many of which are declining rapidly. However, illegal cattle ranching is accelerating deforestation, threatening both birds and local communities.
