The Chestnut-bellied Hummingbird Saucerottia castaneiventris is an endemic hummingbird of Colombia, currently categorized as Near Threatened (NT) globally and as Vulnerable (VU) i…

Agricultural intensification negatively affects bird communities, and the response of birds to these changes varies from those that survive and increase their populations (disturb…

Wetlands currently have high rates of degradation, with more than 70% lost globally. In the central Monte Desert, Argentina, they are a scarce and limited resource for the biodive…

Although there are studies on certain aspects of the feeding ecology of several species of Neotropical parrots, there is scarce ecological information about Pyrrhura molinae – a P…

The northern coast of Honduras is potentially covered with tropical rainforests, reaching from the Caribbean Sea up to the cloud forests of the Pico Bonito summits. Therefore, it …

Activity patterns of species are related to their physiology, their behaviour and the environment and can change in response to different factors, such as interactions between spe…

The aim of the research was to determine the number and distribution of the Rufous-banded Owls Ciccaba albitarsis in a cloud forest on the northern slopes of the Andes. The study …

As urban areas expand, some species of diurnal birds of prey occupy these habitats, and many establish viable populations. The objectives of this study were to: (1) survey the spe…

Captive breeding has been conducted across various regions to restore globally endangered sea turtle populations. However, understanding how turtles adapt to artificial breeding e…

Recovering biodiversity across trophic levels is a major challenge in restoration ecology. Specifically, predator population recovery depends on the timely re-establishment of the…

Identifying of global or national biodiversity ‘hotspots’ has proven important for focusing and prioritizing conservation efforts worldwide. Canada has nearly 600 Important Bird a…

Chile has a large number of wetlands that offer a wide variety of refuges and food to waterbird assemblages. This research hypothesises that these assemblages differ according to …

In Australia, a multi-million-dollar industry is based on viewing the Australian fur seal (Arctocephalus pusillus doriferus), predominantly through boat visits to breeding colonie…

We describe an interspecific relationship wherein grizzly bears (Ursus arctos horribilis) appear to seek out and consume agricultural seeds concentrated in the middens of red squi…

The timing of breeding can strongly influence individual breeding performance and fitness. Seasonal declines in breeding parameters have been often documented in birds, particular…

Numerous studies have examined the effects of the provision of supplementary food on aspects of avian reproductive success, but far fewer have gone on to examine the potential pos…

Nature conservation and agricultural production may be considered as conflicting objectives, but for a wheat and sheep property in Western Australia they have been pivotal managem…

Population size assessments for nocturnal burrow-nesting seabirds are logistically challenging because these species are active in colonies only during darkness and often nest on …

Roads are a pervasive feature in the landscape, and their ecological effects on vertebrate wildlife have been well documented. The main types of effect described are mainly negati…

We present records of winter activity of non-native turtles, especially Trachemys scripta, the most common alien turtle in Romania. This species was observed basking in urban park…

The populations of the widespread European pond turtle and their numbers are decreasing in Hungary and other European countries. Knowledge of basking habits, along with other biol…

Mangroves and mudflats are essential intertidal habitats that support benthic communities, providing critical feeding grounds for waterbirds. However, the degradation of these hab…
