      Maternal inheritance via the female-specific W chromosome was long ago proposed as a potential solution to the evolutionary enigma of co-existing host-specific races (or ‘gentes’) in avian brood parasites. Here we report ...

    • First-time Migration in Juvenile Common Cuckoos Documented by Satellite Tracking 

      Vega, Marta Lomas; Willemoes, Mikkel; Thomson, Robert L.; Tolvanen, Jere; Rutila, Jarkko; Samas, Peter; Strandberg, Roine; Grim, Tomas; Fossøy, Frode; Stokke, Bård Gunnar; Thorup, Kasper (Journal article; Peer reviewed, 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 ...

    • Sex Allocation in Relation to Host Races in the Brood-Parasitic Common Cuckoo (Cuculus canorus) 

      Fossøy, Frode; Moksnes, Arne; Røskaft, Eivin; Antonov, Anton Tinchov; Dyrcz, Andrzej; Moskát, Csaba; Ranke, Peter Sjolte; Rutila, Jarkko; Vikan, Johan Reinert; Stokke, Bård Gunnar (Journal article; Peer reviewed, 2012)
