Why lists of worldwide bird species disagree

Data gaps and species similarities may lead to undercounting biodiversity.


Warming climate slows tropical birds’ population growth rates

A 30-year study in Tanzania shows temperature-linked population declines in species important to forests.


Yes, allergy seasons are getting worse. Blame climate change.

If you live with seasonal allergies and feel like the pollen seasons feel longer and longer every year, you may be right.

Birds are all around, and all you need to get started is an observant eye.


Two African crested rats stand face to face, nuzzling each other. The rodents are rabbit-sized and resembles a gray puffball crossed with a skunk. Their fur is various shades or brown and gray, with dark stripts that line its flanks from leg to its face.

The secret social lives of giant poisonous rats

The African crested rat’s fur is packed with a poison so lethal just a few miligrams can kill a human. Biologists confirmed where it gets its poison, and uncovered an unexpected social life.


Drought’s one-two punch

Researchers look into the effects of repeated droughts on different kinds of forests.


Trees and lawns beat the heat

As climate change pushes cities towards dangerous temperatures, planners must balance mitigating heat and preserving water resources.
