Message: <blockquote data-quote="Steve Dudley" data-source="post: 1709837" data-attributes="member: 5172">I agree Jos. It simply demonstrates the species that have been reliably recorded as EO prey. But at least it demonstrates just that. Some people refuse to accept that EO present any threat to other bird species. Whilst Mikkola's list doesn't not determine threat, it at least allows you to identify the species which may be most at risk locally from the establishment of breeding EOs.The more important aspect of predation on other bird species was mentioned in a previous post when I referred to Mikkola stating that birds have been recorded making up to 51% of EO diet (in Norway). This is perhaps little different to many other top-level predators which specialise in a particular local prey species.</blockquote>
