Splitting my time between Auckland and the Far North means I get to see a lot of New Zealand wildlife—especially when I’m driving through the Waipoua forest. I’ve never really noticed a remarkable difference in the moods of the birds in either place, but I’ve definitely seen some extremely predatory behaviour carried out by the hawks up north. This study, done by Virginia Tech in the US, found that suburban birds were far more territorially aggressive than birds in rural areas. It’s an interesting read and I wonder if anyone in New Zealand has conducted any similar research because the birds I see in the city seem completely passive and docile.
