Pair of geese mating in the shallows of the Severn by the Bylet at Bridgnorth. Like many of the geese which gather on the river there, the male has the all white feathers suggesting feral descent, which is likely also the reason for the female’s patchier white on the plumage.
Notice the aggression involved. The actions also triggered loud and continuing honking from the large number of geese on the Bylet.
