Breeding Storm Petrel survey

I've just received from Danni (Thompson) at JNCC a map showing the survey locations looking for breeding Storm Petrels on Nan Ron. This was undertaken in 1995. It is our intention under Danni's guidance to resurvey the complete island this year for comparison. We're going to be busy......

GPS track on Italian Storm Petrel

Posted by Feberico De Pascalis via his Twitter account (@fdepa1) the first GPS track of an italian storm petrel - a 28g bird travelling up to 200km from its breeding colony foraging in a single day! Wonder if it does this every day?

Good news x2 (or is that three?)

1. We heard, just before Christmas, that one of our grant applications had been successful. Our request to the Seabird Group had been approved, so we have some money in the pot to enable us to molecularly sex some of the birds we catch this year as part of our study on trying to produce a definitive method for pheno-morphological sexing of Storm Petrel (i.e. can you do it by just looking at the bird in the hand together with a few measurements).
2 and 3. Have just had news back of the Portuguese birds caught last year.
Both were initially caught and ringed at the same place - Ponta de Almadena, Portugal - one on the 18th June (N7599) and the other (N7624) on 20th. N7624 was recaptured on Nan Ron on the 30th July and N7599 the next night. So both had covered the 2411km in about 40 days.
