  1. The simple things in life sometimes bring the greatest joy—like feeding the ducks at your local pond. The next time you pay your feathered friends a visit, consider introducing some variety into the food you give them. Just like for us humans, a balanced diet is important for wild animals. The large amounts of bread that people feed wild birds may be well-intentioned, but they could be doing them harm.

  2. In the mountains across the world, different types of vegetation occur at different elevations creating distinct zones with well-defined borders between them. Each vegetation zone provides specific living conditions for animals. Therefore species that are adapted to habitats created in the specific zone occur only at the specific elevations and do not overlap with other species of similar ecology and behavior adapted to other vegetation zones at different elevations. This zonation is believed to be especially true for ecologically similar species that narrowly specialize to use specific resources and therefore compete with each other if they co-occur next to each other in the same habitat.

  3. Many animal species use social information—from conspecifics or other species—to inform their behavioral choices, for example where to look for food or build a nest. In a recent study, ornithologists have shown for the first time that the ability to use such information can depend on an individual's cognitive skills. In the collared flycatcher, females that mastered a learning task faster were more likely to copy the nest site choices of great and blue tits in the same area.

  4. A comprehensive new study into the key user groups in Indonesia's bird trade offers hope for protecting species through behavioural change. Novel research led by Manchester Metropolitan University (MMU) and Chester Zoo has identified three main groups within the Indonesian songbird owner community: 'hobbyist', 'contestant' and 'breeder'.

  5. As migratory birds travel back and forth between their breeding and wintering grounds twice each year, they face many hazards. For species that migrate during the night, one of those dangers is the disorienting influence of light pollution from cities. A new study in the journal Environmental Pollution examines how artificial light at night and urban landcover are associated with the presence of nocturnal migrants across seasons.
