Past research and future directions in understanding how birds use their sense of smell

open access: yesIbis, Volume 167, Issue 4, Page 853-881, October 2025.
Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...

Habitat Protection Alone Is Insufficient: Costa Rican Parrots Thrive in Altered Landscapes but Remain Vulnerable to Poaching

open access: yesDiversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim Human population growth and resource overexploitation have induced major changes in global biodiversity. Costa Rica, with 26% of its land area protected, is often cited as a model of environmental conservation. However, conservation efforts have largely focused on habitat preservation, while overharvesting remains an unquantified factor in
