THE 2015 FIELD SURVEY OF THE BREEDING BIOLOGY AND MORPHOLOGY OF THE SEMI-COLLARED FLYCTACHER JUST STARTED
March 20, 2015: This year’s field season of the four-year study on the breeding biology and morphology of the Semi-collared Flycatcher started with a presentation entitled “The Semi-collared’s breeding cycle based on 40 years experience of the Collared’s”, given by our colleague from Sweden, ornithologist and researcher Johan Traff at the Institute of Biodiversity and Ecosystem Research (IBER) at the Bulgarian Academy of Sciences. For more than 40 years Johan Traff has conducted observations on the breeding biology and morphology of the genus Flycatchers (Ficedula) and in particular of the species from the group of “black and white” Flycatchers (Pied, Collared and Semi-collared Flycatchers).
