By drinking, the sparrow got wet the legs that were then stuck to the barrier because of the icy cold. Nelson then approached the small bird and caught it in his hand to prevent the frightened animal from hurting himself by wanting to fly away, then he blew hot air on his legs to get them off Of the barrier. After a few tens of seconds, the bird was able to regain its freedom.
