The team of National Trust rangers and volunteers will be using ghettoblaster-style high-powered speakers at night to lure storm petrels
in from the sea.
The storm petrel
in particular tells us about a very specific niche in this ecosystem, and these numbers are going to provide a very useful baseline from which we can monitor future trends and react accordingly.
109, I spotted a storm petrel
off to the starboard (right) side of the boat and, as we slowed and managed to get a first glimpse, we were immediately struck by two things: This bird was a completely different in size and structure to Wilson's Storm Petrel
, and it had an all-dark rump.
In recent years, additional storm petrel
colonies have been discovered along the Peruvian and Chilean coast, although very little is known about the breeding biology and numbers of these birds (Jahncke 1992, Schlatter & Marin 1983, Simeone et al.
I was, therefore, on the lookout that Sunday for a rare seabird myself, and I was not disappointed, latching onto my very own Leach's storm petrel
flying down-channel as I approached Rest Bay at the end of the walk just after midday.
At Ardenest, the only seabird species present in the predator deposit was a storm petrel
so that seabird breeding at this site may have ceased over 1000 years ago.
Experimental evidence for regulation of food delivery to Storm Petrel
, Hydrobates pelagicus, nestlings: the role of chick body condition.
Conservationists will be searching two Pembrokeshire islands, Skokholm and Skomer, for the most enigmatic sea bird in Wales - the European storm petrel
In addition, the project expects to benefit a range of other species, including European storm petrel
(Hydrobates pelagicus) and Manx shearwater (Puffinus puffinus).
Several hundred Max shearwaters flew past Rhos Point, with a brace each of Arctic, great and Pomarine skuas, and a storm petrel
that should be heading to northern breeding grounds.
When the winds are right, we sometimes get endless passages of shearwaters and kittiwakes, black guillemots and razorbills, and in among them, we're always looking out for the rarer Arctic skua or storm petrel
