In prey species, it is often the case that individuals give alarms when they are threatened. In birds, such signals are frequently vocal signals that alert conspecifics to the presence of a threat. The responses to these calls by receivers may include fleeing to cover or approaching to mob the predator. Although most birds do give alarm calls when...

One of the most challenging problems faced by ecologists and other biological researchers today is to analyze the massive amounts of data being collected by advanced monitoring systems like camera traps, wireless sensor networks, high-frequency radio track-ers, global positioning systems, and satellite tracking systems being used today. It has beco...

Agricultural ornithology describes relationship between birds and agro ecosystems; it's an emerging field of keen interest among ornithologists of agriculture dominating countries. Indian subcontinent provides habitat to about 1300 resident or migratory bird species (13% of the world's avifauna) including 141 endemic species. Agro-ecosystems are ma...

The description of the long-tailed cuckoo's (Eudynamys taitensis) egg was uncertain until the 1930s. Edgar Stead published evidence in 1936 that it was white with darker (red-brown or purplish) speckles, and therefore mimetic in colour and pattern (as well as size) to the eggs of many small song-birds in New Zealand. In reviewing eggs in museum col...

Zoos are well-known for conservation efforts benefiting wildlife, including some European bird species such as the bearded vulture Gypaetus barbatus and waldrapp ibis Geronticus eremiticus. In Italy there has generally been a lack of scientific interest towards zoos, and ornithology is no exception. Yet, zoo collections not only may present valuabl...

Birds use stopovers during migration to interrupt endurance flight in order to minimize immediate and/or future fitness costs. Stopovers on ships is considered an exceptional and anecdotal event in the ornithological literature. This does not match the experience we had in the summer of 2021, during an oceanographic campaign in the Central Mediterr...

We used the Collections Health Index (ISC) to assess the conservation status and to identify management priorities of the bird collection of the National Institute of Biodiversity (INABIO) of Ecuador. We analyzed the physical status and associated information of all the birds deposited in the collection, in two different periods. In 2014, the numbe...

In ecological studies sampling must be stratified to ensure a sample population that best represents the entire population studied. Meta-analyses assessing global patterns should also use a stratified data structure to ensure unbiased results. We show that this is generally not the case, as individual studies are heavily biased toward the Norther...

Ornithology holds one of the most polarized debates over species concepts. This debate has traditionally been centered around the Biological Species Concept and the Phylogenetic Species Concept, but more recently a third concept, the General Lineage Species Concept, has been gaining ground in the field. The latter concept, however, has been widely...

Agroforests can play an important role for biodiversity conservation in complex landscapes. A key factor distinguishing among agroforests is land‐use history ‐ whether agroforests are established inside forests or on historically forested but currently open lands. The disparity between these land‐use histories means that the appropriate biodiversit...

We study set-valued classification for a Bayesian model where data originates from one of a finite number $N$ of possible hypotheses. Thus we consider the scenario where the size of the classified set of categories ranges from 0 to $N$. Empty sets corresponds to an outlier, size 1 represents a firm decision that singles out one hypotheses, size $N$...

Birds face the challenge of avoiding predators, yet the postural adjustments they use to aid their thermoregulation (resting the bill on their back plumage and standing on one leg), may diminish their capacity to detect and escape from approaching predators. This may lead to a temperature-mediated trade-off between anti-predator and thermoregulator...
