Austin Roberts Bird Sanctuary animals. The natural veld type of the sanctuary is mixed bushveld. Upwards of 170 native bird species have been recorded, but the presence or breeding of some have been transient, due to urbanization and other factors. Resident or visiting passerine birds include thick-billed weaver, southern red bishop, African reed-warbler, little rush-warbler and lesser swamp-warbler. Various heron species visit the reserve, including black-crowned night-heron, little bittern, green-backed heron, purple heron, black and little egret. Other regular water birds are red-knobbed coot, fulvous duck, Egyptian goose, white-faced duck, Cape teal and southern pochard. Pinioned crowned cranes and blue cranes have been released
What Is a Nation? and continues to be invoked. Political historian Karl Deutsch, in a quote sometimes mistakenly attributed to Renan, said that a nation is "a group of people united by a mistaken view about the past and a hatred of their neighbours". Benedict Anderson's 1983 work Imagined Communities, which states that a nation is an "imagined political community", argues that Renan contradicts himself when he says French people must have forgotten the St. Bartholomew's Day massacre, yet does not explain what it is. In other words, Renan assumes that all his readers will remember the very massacre he says they have forgotten.
