A paper published this month in Deinsea highlights several examples of magpies and carrion crows building nests with strips of anti-bird spikes in both Rotterdam and Antwerp. Magpies are particularly enterprising and use pointed edges for their original purpose: many have lined the roofs of their homes with the spikes to deter predators from snatching eggs.

In August 2006, Perelman was offered the Fields Medal[4] for "his contributions to geometry and his revolutionary insights into the analytical and geometric structure of the Ricci flow", but he declined the award, stating: "I'm not interested in money or fame; I don't want to be on display like an animal in a zoo."[5]

On 18 March 2010, it was announced that he had met the criteria to receive the first Clay Millennium Prize[7] for resolution of the Poincaré conjecture. On 1 July 2010, he rejected the prize of one million dollars, saying that he considered the decision of the board of the Clay Institute to be unfair, in that his contribution to solving the Poincaré conjecture was no greater than that of Richard S. Hamilton, the mathematician who pioneered the Ricci flow partly with the aim of attacking the conjecture.[8][9]

In 2005, Perelman abruptly quit his research job at the Steklov Institute of Mathematics, and in 2006 stated that he had quit professional mathematics, due to feeling disappointed over the ethical standards in the field. He lives in seclusion in Saint Petersburg, and has not accepted offers for interviews since 2006.

The writer Brett Forrest briefly interacted with Perelman in 2012.[64][65] A reporter who had called him was told: "You are disturbing me. I am picking mushrooms."[66]
