    Evidence for vocal signatures and voice-prints in a wild parrot 

    Smeele, Simeon Q.; Senar, Juan Carlos; Aplin, Lucy M.; McElreath, Mary Brooke (Publication date: 2023-10)

    In humans, identity is partly encoded in a voice-print that is carried across multiple vocalizations. Other species also signal vocal identity in calls, such as shown in the contact call of parrots. However, it remains ...

    Dispersal behaviour and settlement in an invasive bird: dispersers prefer their natal habitat 

    Dawson Pell, Francesca S. E.; Hatchwell, Ben J.; Carrillo-Ortiz, José G.; Ortega-Segalerva, Alba; Uribe, Francesc; Senar, Juan Carlos (Publication date: 2023-10-01)

    Habitat selection has profound consequences for individual fitness, but how do animals decide where to settle? The natal habitat preference induction (NHPI) hypothesis proposes that individuals choose habitats that exhibit ...

    The effect of climate change on avian offspring production: a global meta-analysis 

    Halupka, Lucyna; Senar, Juan Carlos; Halupk, Konrad (Publication date: 2023-03-22)

    Climate change affects timing of reproduction in many bird species, but few studies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders ...

    Heterospecific nest material kleptoparasitism: observations of grey herons, Ardea cinerea, removing material from the nests of monk parakeets, Myiopsitta monachus 

    Dawson Pell, Francesca S. E.; Senar, Juan Carlos; Hatchwell, Ben J. (Publication date: 2023-04)

    Nest material kleptoparasitism occurs when an individual steals material from another individual's nest. Here we document 69 observations of grey herons, Ardea cinerea, removing nest material from the nests of monk parakeets, ...
