Pine grosbeaks are rare winter visitors to the UK from Scandinavia appearing in irruption years when northern seed crops fail, with welfare challenges as unfamiliar visitors.
Pine grosbeaks that reach the UK during irruption years face welfare challenges from unfamiliarity with the habitat and climate. Their tameness makes them vulnerable to disturbance from birdwatchers and to predation. Finding adequate food in an unfamiliar landscape requires adjustment. The return journey north may be hazardous for birds that have depleted fat reserves. Their welfare is best served by giving them space to feed undisturbed.
