Kind: research · Impact: medium

## In brief

- A study finds tropical cities lose a larger share of bird species as urban areas expand than cities at higher latitudes.
- Tropical regions have high bird diversity, which the study links to greater losses from urbanization.
- The source is a short excerpt, so further specifics such as sample size and methods are not available here.

## Why it matters

Urban expansion in the tropics may remove a disproportionate share of bird diversity, which matters for conservation planning in fast-growing tropical cities.
