A game demonstrating aspects of bumblebee natural history [PDF]

, 2004
The Bumblebee Game is an exciting outdoor game, which demonstrates aspects of bumblebee natural history including food chains, food webs and competition for food, predation by crab spiders, parasitism by Conopidae (Diptera) and brood parasitism by ...

Bird brood parasitism [PDF]

Current Biology, 2013
For many animals, the effort to rear their young is considerable. In birds, this often includes building nests, incubating eggs, feeding the chicks, and protecting them from predators. Perhaps for this reason, about 1% of birds (around 100 species) save themselves the effort and cheat instead. They are obligate brood parasites, laying their eggs in the

Multiparasitism and repeated parasitism by the great spotted cuckoo Clamator glandarius on its main host, the magpie Pica pica: effects on reproductive success, nest desertion and nest predation

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.

Reed Warbler Hosts Do Not Fine-Tune Mobbing Defenses During the Breeding Season, Even When Cuckoos Are Rare

Frontiers in Ecology and Evolution, 2021
Hosts of brood parasitic cuckoos often employ mobbing attacks to defend their nests and, when mobbing is costly, hosts are predicted to adjust their mobbing to match parasitism risk. While evidence exists for fine-tuned plasticity, it remains unclear why

A game-theoretic model of interspecific brood parasitism with sequential decisions [PDF]

, 2008
The interaction between hosts and parasites in bird populations has been studied extensively. This paper uses game-theoretic methods to model this interaction.

Personality of hosts and their brood parasites [PDF]

Current Zoology, 2021
AbstractBrood parasites such as the common cuckoo Cuculus canorus exploit the parental abilities of their hosts, hosts avoid brood parasitism and predation by showing specific behavior such as loss of feathers, emission of fear screams and contact calls, displaying wriggle behavior to avoid hosts or potential prey, pecking at hosts and prey, and ...

The Supercooling Responses of the Solitary Bee Osmia excavata (Hymenoptera: Megachilidae) under the Biological Stress of Its Brood Parasite, Sapyga coma (Hymenoptera: Sapygidae)

Insects, 2022
(1) Background: Many insects have evolved different strategies to adapt to subzero temperatures and parasites, but the supercooling response of pollinator populations under the brood parasitism pressure has not been sufficiently investigated. (2) Methods:

Ranging behavior of female and male Shiny Cowbirds and Screaming Cowbirds while searching for host nests [PDF]

, 2014
Pusimos a prueba la hipótesis que los tordos parásitos de cría buscan y localizan nidos de hospedadores dentro de un área relativamente constante, ya que esto facilitaría el monitoreo de nidos a través del tiempo y la sincronización del parasitismo con ...

Evidence for Interspecific Brood Parasite Detection and Removal in Burying Beetles

Psyche: A Journal of Entomology, 2018
We tested whether brood parasitism could be successful between two co-occurring species of burying beetles, Nicrophorus guttula and Nicrophorus marginatus, and whether these species exhibit an adaptive response to brood parasitism by detecting and ...
