Challenges in population monitoring: Bar‐tailed Godwits (Limosa lapponica) on the East Atlantic Flyway defy assumed population structure

Ibis, EarlyView.
Estimating and monitoring migratory bird populations involves significant challenges, even in the most well‐studied and easily‐counted species, and can be further complicated by long‐held but unverified assumptions and by shifting distributions in changing flyway conditions.

Species characteristics predict the effectiveness of avian survey methods in an Afromontane sky‐island

Ibis, EarlyView.
Biodiversity conservation requires effective monitoring of ecological communities in remote locations, where limited accessibility often restricts survey efforts. Passive acoustic monitoring (PAM) is becoming an established method for measuring biodiversity, facilitated by the increased accessibility of autonomous recording units.

Stable isotope data indicate origins of mislabelled historical bird specimens

Ibis, EarlyView.
Natural history specimens provide valuable insights across diverse research fields, but those needing more accurate metadata have limited scientific value. We applied stable isotope analysis to investigate the origin of 19th century Atlantic Forest bird specimens attributed to the northeastern Brazilian state of Pernambuco, which are the only records ...

Field‐based evidence of impaired sperm quality associated with conventional farming in two passerine birds

Ibis, EarlyView.
The detrimental effects of conventional farming on bird biodiversity are increasingly documented. Despite this, the specific impacts of both organic and conventional farming practices on bird coloration and sperm quality in natural settings remain unexplored. This study aimed to determine whether these farming practices differentially affect body mass,

A new species of jewel‐babbler (Cinclosomatidae: Ptilorrhoa) from the Southern Fold Mountains of Papua New Guinea

Ibis, EarlyView.
Based on distinctive morphological and vocal characters we describe a new species of jewel‐babbler (genus Ptilorrhoa) from the forested karst of the Southern Fold Mountains in Papua New Guinea. The description is based on camera trap data and is presented in accordance with ICZN Declaration 45.
