Timing pattern of Common Cuckoo parasitism and its relation to host nest attendance

open access: yesIbis, EarlyView.
Classical works show the adaptive importance of precise timing of egg‐laying in brood parasitic Common Cuckoos Cuculus canorus to ensure sufficient incubation time and successful hatching. Laying in the late afternoon has been suggested to increase the chance of secretive parasitism and therefore escape the aggressive mobbing by hosts, yet this ...

First-Time Migration in Juvenile Common Cuckoos Documented by Satellite Tracking

open access: yesPLOS ONE, 2016
Being an obligate parasite, juvenile common cuckoos Cuculus canorus are thought to reach their African wintering grounds from Palearctic breeding grounds without guidance from experienced conspecifics but this has not been documented. We used satellite tracking to study naïve migrating common cuckoos.

Trans‐oceanic migration and wind utilization by Amur Falcons (Falco amurensis)

open access: yesIbis, EarlyView.
The Amur Falcon Falco amurensis performs one of the world's longest raptor migrations, involving a non‐stop crossing of the Indian Ocean of approximately 2800 km. While the existence of this route is known, the mechanistic details of wind exploitation and seasonal navigation remain to be fully elucidated.

Random‐key optimization for 2D irregular packing with reusable area evaluation

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The diverse constraints of industrial applications lead to variants of two‐dimensional (2D) irregular packing problems that require tailored solution methods. This paper addresses a real‐world industrial challenge by proposing a new problem definition, the maximum reusable contiguous area problem (MRCAP), and a novel metric, the maximum ...

Separable solutions to a brood-parasite dynamics model

open access: yesUniversal Journal of Mathematics and Applications, 2018
Common Cuckoo is a brood-parasite which lays its egg in the nest of other bird species and use them to raise its young. We present a Common Cuckoo and a host bird interaction deterministic model taking into account maternal care of offspring. The model

Outcomes of brood parasite-host interactions mediated by egg matching: common cuckoos Cuculus canorus versus Fringilla finches. [PDF]

open access: yesPLoS ONE, 2011
Antagonistic species often interact via matching of phenotypes, and interactions between brood parasitic common cuckoos (Cuculus canorus) and their hosts constitute classic examples.

Seasonal increase in nest defense, but not egg rejection, in a cuckoo host

open access: yesAvian Research
The interactions between avian brood parasites and their hosts provide an informative and easy-to-handle system for studying coevolution. Avian brood parasitism reduces the reproductive success of hosts, and thus, hosts have evolved anti-parasitic ...
