Parrot Crossbill
Loxia pytyopsittacus

– medium-sized passerine, slightly larger than Red Crossbill
– diurnal migrant
– migrates singly or in small to medium loose flocks

– no ecomorphs with different measurements and ‘call types’ described in Europe so far (ROBB 2000)
– however, probably different ‘call types’ might exist, but nothing is published yet to proof that
– juvenile flight calls show obvious plasticity, but just for a short period of time
– adult flight calls show obvious plasticity too, mostly during the breeding period
– calls learned from parents or other conspecifics near nest
