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

Assessing relative hazard, risk, and seasonal differences of wildlife‐aircraft collisions
Wildlife collisions with aircraft have occurred since the inception of aviation, with significant safety and economic implications. Strike risk models are used to assess the probability of an adverse event between wildlife and aircraft, providing information to guide wildlife management at airports. This study builds upon DeVault et al.

Review Understanding Ethno-Ornithology - Birds of the Residents?
This research, conducted between November 2019 and May 2020 in Jaguarari, Bahia State, aimed to inventory birds used for trophic purposes, capture techniques, zootherapeutic uses, caged birds, and their associations with local myths and legends.

This study highlights the biodiversity value of the Murren Reserve, a small tropical dry forest patch in Guanacaste, Costa Rica. Using camera traps and opportunistic observations, researchers documented 32 wildlife species, including federally endangered species like the ocelot (Leopardus pardalis) and puma (Puma concolor), as well as 73 plant species.

Vulture Exclusion Halves Large Carcass Decomposition Rates and Doubles Fly Abundance
We experimentally excluded vultures from pig carcasses (Sus scrofa) in Costa Rica, under different habitats and across seasons with the aim to assess the impact of vulture population decline on carrion decomposition and insect abundance. Vulture exclusion halved carcass decomposition rates and doubled fly abundance, while dung beetle abundance remained

Heavy metal levels in plasma and fecal material samples of the black vulture (Coragyps atratus)
The level of cadmium (Cd), copper (Cu), lead (Pb), vanadium (V), and zinc (Zn) were determined in blood plasma samples of healthy black vultures (Coragyps atratus) (n = 10).

This study employs passive air sampling to detect environmental DNA (eDNA) of bats using DNA metabarcoding and a novel qPCR assay for the imperiled tricolored bat (Perimyotis subflavus). Metabarcoding successfully allowed detection of two bat species in one sample, and qPCR allowed detection of the tricolored bat in two samples, providing a lower bound

Bait trapping of waterfowl increases the environmental contamination of avian influenza virus (AIV)
Metrics of avian influenza virus (AIV) occurrence and diversity derived from fecal and sediment sampling at quasi‐experimentally baited and un‐baited sites provided evidence that wetland baiting of waterfowl increases AIV contamination in the environment.
