Abundance and prey capture success of Common Terns (Sterna hirundo) and Pied Kingfishers (Ceryle rudis) in relation to water clarity in south-east coastal Ghana

open access: yesAvian Research, 2018
Background Water clarity may negatively influence rate of plunge diving and prey capture success of piscivorous plunge-diving birds, and therefore has implications for their conservation in polluted urban wetlands.

An Integrative Approach to Assessing the Impact of Mercury (Hg) on Avian Behaviour: From Molecule to Movement

open access: yesJournal of Xenobiotics
Mercury (Hg) pollution is a widespread ecological threat with sublethal effects on wildlife. Birds, due to their ecological diversity and sensitivity, serve as effective models for evaluating the behavioural impacts of Hg exposure.

Spatio-temporal distributions of piscivorous birds in a subarctic sound during the nonbreeding season

open access: yesDeep Sea Research Part II: Topical Studies in Oceanography, 2018
Abstract Understanding bird distributions outside of the breeding season may help to identify important criteria for winter refuge. We surveyed marine birds in Prince William Sound, Alaska, USA over nine winters from 2007 to 2016. Our objectives were twofold: to examine the seasonal patterns of piscivorous species overwintering in Prince William ...

Lake eutrophication and brownification downgrade availability and transfer of essential fatty acids for human consumption

open access: yesEnvironment International, 2016
Fish are an important source of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) for birds, mammals and humans. In aquatic food webs, these highly unsaturated fatty acids (HUFA) are essential for many physiological processes and mainly ...

Aspects of the ecology of piscivorous birds of Lake Kyle Rhodesia [PDF]

open access: yes, 1969
[From Introduction]. From an early period in the lake's history research was undataken to determine the potential of Kyle as a source of edible fish, In such a study, knowledge of the number and weight of fish consumed by piscivorous birds would seem to ...

Aspects of population dynamics and feeding by piscivorous birds in the intermittently open Riet River estuary, Eastern Cape, South Africa

open access: yes, 2011
Aspects of the population dynamics and feeding activity of piscivorous birds in the small (c. 5 ha) intermittently open Riet River estuary, on the south-eastern coastline of South Africa, were investigated monthly from August 2005 to July 2006.

Avian diversity and ethnoornithology in Pawukon - a 19th-Century Javanese manuscript : informing contemporary conservation of vulnerable species

open access: yesJournal of Ethnobiology and Ethnomedicine
The progressive erosion of Traditional Ecological Knowledge (TEK) in Java, a process exacerbated by colonial disruption, has created a critical disjuncture in biodiversity data.

Urban waterbirds shifting microplastics

open access: yesEnvironmental Challenges
Plastic pollution in aquatic ecosystems poses growing ecological risks, particularly for piscivorous birds occupying higher trophic levels. This study assessed the ingestion and excretion patterns of microplastics (MPs) in two monotypic urban inland ...
