At the little tern site at Seaton Carew, we welcome most visitors, but yesterday saw the return of perhaps our least-welcome visitor. Unfortunately, there are many animals for whom a little tern egg or chick will make a meal or a snack, either for them or their young. Our night wardens do a great job of deterring mammals such as foxes, hedgehogs, cats and stoats, and the little terns themselves are adept at seeing off larger birds. To date, though, the kestrel is one predator that we struggle to keep out of the site. Although we recognise that they also have to eat - both kestrels and terns are carnivorous (the latter being a piscivore, eating fish) - it is heart-breaking to see them prey on birds within the site. Yesterday saw a tern chick predated, and this behaviour unsettles the entire colony. The little terns made a concerted effort to drive out the kestrel, taking turns to dive at it whilst it was on the ground, but to no avail. They were, however, successful in driving it out when it then made a return visit, with a small number of individuals pursuing it relentlessly until they were sure that it wasn’t going to double back. We hope that the terns can now get back to incubating their eggs and feeding the ever-growing number of chicks.
Nature is beautiful, but it can also be cruel.
