Heads in the Sand in Ayrshire?

There is a report (https://theguardian.com/world/2016/jul/27/ostriches-on-the-loose-in-scottish-village-patna) that an ostrich (or ostriches?) is (are) roaming the countryside around the Ayrshire village of Patna. This has caused much excitement as an ostrich can disembowel animals it regards as a threat with a single kick. It has also been pointed out that mother ostriches (the more dowdy bird) can be very defensive when protecting their chicks (and there was been speculation about whether the escaped bird has chicks). After initial vagueness about where the bird(s) came from, one resident has apparently admitted that a bird has gone AWOL. I wonder if it qualifies as a dangerous animal?
