We’d gone down to Booterstown for our October
count of wintering waders, waterfowl, geese and gulls. The day hadn’t
started very promising, the rain had been fairly pelting down earlier
but at 7.45 it seemed to be easing off. The other counters had been
sitting in their cars waiting for the rain to clear so we all prepared
ourselves and crossed over the DART line down to the strand. Behind
us to the west the sky was a very ominous curtain of black from cloud
to ground. We hoped it was rain moving away but unfortunately it wasn’t,
it was coming towards us and we’d barely started to count the
birds on the strand before it started to torrent down on us. We splashed
back to the shelter of the covered pedestrian bridge over the DART
station. Out of the rain and being able to see through the telescopes
again we resumed the counting and were looking down on the marsh with
its little flocks of Black Tailed Godwits, Redshank and Dunlin when
Lucy drew our attention to a drama taking place on the other side
of the railway line. A raptor was diving down on a shallow stretch
of seawater near the tidal wall. Through the rain we couldn’t
figure out for a minute or two what it was then realised it was a
fairly bedraggled Peregrine, a bird usually seen scything through
the air to get its prey but here it was diving on a Bar Tailed Godwit
wading in the pool. Every time it dived the godwit, itself quite a
tall wader, would duck down under the water, completely submerging
itself. |
Don’t
know what the godwit’s strategy was, did it think standing beside
the oystercatcher would make it a more difficult target. It looked like
a desperate attempt to save itself and you couldn’t help but pity
the godwit. The peregrine kept diving, the godwit kept ducking while
the oystercatcher stood immobile. The peregrine broke off its attack
perching on one of the metal posts on the DART station platform where
hooded crows harassed it.
We
had to return to counting birds in the marsh but when we looked back
a few minutes later the peregrine was gone and we were delighted to
see the godwit had survived and was striding around the pool poking
its long bill into the mud for food. The name godwit is a derivative
of ‘good to eat’ from the time when they used be hunted
for the table but this particular individual had no intention of being
the peregrines delicacy this particular morning. |
The
view over Killiney Bay from the rocks near the obelisk is lovely in its
own right and is often enhanced by the sight of a porpoise, dolphin or
some interesting bird passing by. In early autumn we’d seen late
swifts, then flocks of swallows and house martins sweeping south in the
shelter of the hill where the air is calmer and warmer and would support
a lot more flying insects for them to feed on. I was sitting on the rocks
when a pair of ravens drifted across the tree tops below before settling on the tops of two adjacent macracarpa trees and having a croaky conversation with each other. Ravens have a fantastic range of sounds, apparently producing at least thirty distinct sounds, and more than any other bird they sound like they actually might be articulating thoughts when they call. When flying they often fold their wings and roll over for seemingly no other reason than to have a bit of fun. After exchanging some more calls to each other they took off, flying south round towards Killiney but seconds later they had returned flying up towards the summit of the hill. Just then I heard more croaking behind me and looked around to see more ravens approaching from the direction of Dalkey Island. The first two ravens joined this group and the flock, now numbering ten, headed off towards the Dublin Mountains; not a big flock in number but a very impressive collection of these wonderful creatures. Ravens were once only associated with remote mountains and cliffs so when we were in Oak Park Wood in the very flat countryside just outside Carlow Town in October a pair of ravens croaking over the treetops were quite an unexpected sight but a clear indication they’re expanding their range and habitat.Usually in the grove of pines where we saw the female squirrel I’d be keeping my eyes trained upwards to the treetops so it was lucky I spotted a beetle on the ground before I stepped on it. It moved with the rear of its long body curved upward like a tiny scorpion, shiny black apart from two tiny white tips at the end of its abdomen which on closer inspection turned out to be two tiny pincers. Afraid that somebody, probably me, would step on it I tried to move it somewhere safer. I attempted to get it to climb on to a leaf then held my hand down flat so it could climb on but it refused my entreaties and eventually dug down under some leaves and twigs, moving a fallen pine cone in the process which I thought quite impressive for a tiny creature. I had my suspicions what it was and sure enough on subsequently checking I found it was the dramatically named Devil’s Coach Horse Beetle (Ocypus olens). They are ‘voracious predators active at night, when they consume small slugs and snails, and a wide range of other invertebrates’. I also read that the scorpion’s pose was a defensive action and when threatened it can emit a foul smelling odour from the two white pincers as well as inflict a nasty bite so I was glad it had ignored my hands-on approach. This beetle has been associated with the Devil since the Middle Ages, hence its common name. Other names include Devil’s Footman or Devil’s Steed. |
