Their study explores how microbiome diversity impacts the birds' health, body condition, and ornamental traits, such as their coloration. This research provides the first detailed insights into ...

Birds are molting earlier each fall. A University of Utah study links this shift to climate change and its impact on ...

“We found that the impact of changes in birds’ body size on recruitment and survival was variable across species, but those relationships were in the opposite directions. For example, if we saw a ...

This suggests that being exposed to different climatic conditions has driven the evolution of differences in body temperature and heat tolerance among birds from different climates. The findings ...

Egg binding is when a fertile female bird struggles to release an egg from her body naturally. This is an extremely uncomfortable, painful condition that can become fatal if not properly addressed.

Using computational modeling, the researchers calculated how much energy it would be needed for each bird to maintain its body temperature given the local weather conditions. The migrants ...
