2017 summer fieldwork update


Peregrines
Dean Jones reported the finding of two rings from Peregrine kills on 12th July, whilst out with researchers Luke Sutton and Seb Loram. One was from a freshly predated Manx Shearwater ringed as an adult in 29th August 2011. The other ring, an AA ring inscribed HRC365 and found in a pellet on the West Side, came from a very unexpected prey item for a Peregrine: a Long-tailed Tit ringed by Rob Duncan on 3rd April 2016. It was one of a small flock that was on the island that spring, and was perhaps most likely predated when flying along the East Side or even heading off towards the mainland.

Luke Sutton remarks: “Over the seven years I have been studying Peregrine diet in Devon these are the first remains/pellets I've found with rings. So to get two in the space of five minutes was unusual. I've recorded Long-tailed Tit once before at a South Devon coastal site – not much of a meal at just 8 grams! Elsewhere, the remains of a Razorbill pullus found in a Peregrine territory on the West Side suggests that this prey item was taken off a breeding ledge. We have now finished our fieldwork on Peregrine diet. Over the past four seasons we've collected more than 500 prey samples, the largest sample size for any study on coastal Peregrine diet in the UK. Data analysis will start over the winter with the aim of having a paper written by this time next year for publication. My thanks to Seb (Loram) and Ryan (Burrell) for putting in the time and effort to help collect such a substantial sample size.”

Wheatears
Tony Taylor reports an excellent season for breeding Wheatears, in spite of the grim weather during Richard & Rebecca Taylor’s second week on the island in early June. A total of 99 colour-ringed birds were located in the study area (extending from Castle Hill to Halfway Wall), with 51 birds newly colour-ringed (two of them ringed as chicks in 2016) and 48 from previous years. 61% of last year’s birds were re-sighted – a good survival rate for the species – and this may rise if the study team catch up with other birds next year. The estimate for the whole island in 2017 is 121 breeding pairs, the highest so far.

Manx Shearwaters
Tony Taylor arrives on Lundy on 15th August to start the annual autumn ringing programme, which runs from mid-August through to mid-September.
