Quintuple parasitism of a great reed warbler nest by common cuckoos
Ecology and Evolution, 2021 Multiple parasitism in obligate avian brood parasites occurs when several brood parasitic females lay their eggs in the nest of the same host. While multiple parasitism is common in the highly social, nonevicting cowbird species (Molothrus sp.), in which

Rivista Italiana di Ornitologia - Research in Ornithology, 2022 Interspecific brood or nest parasitism is a relatively common breeding behavior in birds. Through this reproductive tactic, brood-parasites avoid the costs associated with raising and maintaining chicks by laying their eggs in the nests of the host ...

Egg shape mimicry in parasitic cuckoos [PDF]
Journal of Evolutionary Biology, 2017 AbstractParasitic cuckoos lay their eggs in nests of host species. Rejection of cuckoo eggs by hosts has led to the evolution of egg mimicry by cuckoos, whereby their eggs mimic the colour and pattern of their host eggs to avoid egg recognition and rejection. There is also evidence of mimicry in egg size in some cuckoo–host systems, but currently it is

The Adaptiveness of Defence Strategies Against Cuckoo Parasitism [PDF]
Bulletin of Mathematical Biology, 2002 Host bird species of the Eurasian Cuckoo, Cuculus canorus, often display egg-discrimination behaviour but chick-rejection behaviour has never been reported. In this paper, we analyse a host-cuckoo association in which both population dynamics and evolutionary dynamics are explored in a discrete-time model.

Journal of Avian Biology, 2023 Brood parasites are expected to lay only one egg per parasitized nest, as the existence of several parasitic nestlings in a brood increases competition and can lead the starvation of some of them.

Multivariate time series analysis for short-term forecasting of ground level ozone (O3) in Malaysia [PDF]
, 2021 The declining of air quality mostly affects the elderly, children, people with asthma, as well as a restriction on outdoor activities. Therefore, there is an importance to provide a statistical modelling to forecast the future values of surface layer

Potential cuckoo hosts have similar egg rejection rates to parasitized host species
Avian Research, 2020 Background Thrush species are rarely parasitized by cuckoos, but many have a strong egg recognition ability. To date, there is a limited understanding of the relationship between host egg rejection and cuckoo parasitism rate.

Transmission of Urgency Levels in the Alarm Calls of the Oriental Reed Warbler. [PDF]
Ecol EvolPrevious studies revealed that oriental reed warblers (Acrocephalus orientalis) produce alarm calls containing diverse syllable types in response to intruders. We selected three distinct syllable types from these calls (B, D and F alarm calls) for playback experiments to test whether different syllable types convey graded urgency information. Our study

Causative factors of construction and demolition waste generation in Iraq Construction Industry [PDF]
, 2021 The construction industry has hurt the environment from the waste generated during construction activities. Thus, it calls for serious measures to determine the causative factors of construction waste generated.

Ecology and Evolution, 2022 Avian brood parasitism is reproductively costly for hosts and selects for cognitive features enabling anti‐parasitic resistance at multiple stages of the host's breeding cycle.
