Oycs & Ringos

Not only have the Little Terns done well this year down at the Kilcoole colony but so have the Oystercatchers & Ringed Plovers. This isn't surprising given that they also benefit from the extra protection from predators & human disturbance afforded by the fencing & 24 hour a day wardening. 

A total of 15 nesting attempts were made by 7-8 pairs of Ringed Plovers, comprising of 2 pairs in the N-colony, 4-5 pairs in the K-colony & another pair just to the north of the K-colony fencing in the buffer zone. Most of these pairs laid early enough to allow them to raise their first brood & then try again for a second. 

The two pairs that bred in the N-colony were predated at the egg stage, most likely by Hooded Crows, but one pair did manage to hatch it's chicks from a second nesting attempt. Otherwise, only a handful of eggs failed to hatch & these usually involved eggs in second clutches which is to be expected.

So all in all, 43 chicks hatched with a maximum of 37 fledging of which 31 were ringed. This is a great result compared to last year when 6 pairs bred but hardly raised any young to fledging for reasons unknown.

The two pairs of Oystercatchers that nested on the beach (a pair each in the K & N-colony) both laid 3 eggs of which which 2 hatched from each nest. The parent Oycs did a great job keeping their young well fed & out of danger, chasing every gull & crow that approached in anyway close with the result that all 4 Oyc chicks fledged & can now been seen feeding in The Breaches estuary. A third pair also bred nearby in Webb's field, fledging two young. Again, another improvement on last year when both pairs on the beach fledged single young each whilst the Webb's field pair was predated at the egg stage.

Despite doing well off the back of nesting within the fenced area of the beach, the poor Oycs did have to put up with a summer of being harassed daily by the Little Terns! © Jamie Durrant

  1. I've really enjoyed catching up on your blog just now. It's been a few weeks since I walked down your way and I'm sorry now.

    As a local resident, thank you for all your hard work and dedication. It looks like this year has been a great success!
