The mayor of Roddickton, Newfoundland, has called on the federal government to deal with an invasion of harp seals that has seen the creatures blocking roads and wandering streets. Sheila Fitzgerald said there is a reasonable concern that the apparently disoriented seals might become aggressive if approached by humans. A CBC story this week suggested the invasion “was almost” reminiscent of Hitchcock’s movie The Birds. Yet the sight of seals crawling down the streets of the Great Northern Peninsula town is most unusual and has left some locals concerned. One expressed concern that the seals would not find their way back to the ocean, fearing they would head further inland and die. He was also concerned that people might unwittingly get too close to the animals which he worried might make the seals turn aggressive.
