Taste or gustation is the sense evolving from the chemo-sensory system present in the oral
cavity of avian species, which evolved to evaluate the nutritional value of foods by detecting …

The analysis of prey DNA in faeces is a non‐invasive approach to examine the diet of birds.
However, it is poorly known how gut transition time, environmental factors and laboratory …

DNA metabarcoding is a popular tool for animal diet studies to address a variety of research
topics across disciplines and taxa. Despite its widespread use, there has been relatively little …

Scat DNA metabarcoding is increasingly being used to track the feeding ecology of elusive
wildlife species. This approach has greatly increased the resolution and detection success …

The chemical senses generally fall into three categories: chemesthesis (irritation and pain),
olfaction (smell), and gustation (taste). Traditionally, the emphasis in describing …

Traditional methods to study raptor diet are usually limited temporally, eg prey remains at
nesting sites, and are unsuitable to examine dietary changes throughout the year. Using …

The appropriate structure of the digestive tract is crucial for individual adaptation to
ecological conditions. In birds, the length of the small intestine, responsible for food …

In sexually size-dimorphic species, physiological constraints derived from differences in
body size may determine different food requirements and thus a trophic niche divergence …

Males and females are known to differ in a whole suite of characteristics, such as
morphology, physiology, ecology, and behavior. Intersexual differences are generally …

It has recently been recognized that flowers pollinated by generalist opportunistic
nectarivores tend to have different nectar properties to those pollinated by specialist …
