Is this a non chronological report?

Unfortunately I would say that is is not a non chronological report as the last paragraph deals with the events of a giraffe's life from birth to around 15 months, with the events taken in order - chronological, although this bit is not the basis of the whole article, so you could get away with it. I suspect you need to find an article that doesn't mention dates or times or takes you through events in order. Good luck!
