Data crunching begins.

Having acquired the consent of all ringing groups and individuals that have ringed Storm Petrels on Nan Ron over the years, the BTO have released all the data in the central database to me. Primarily this consists of two sets of records - all the new birds and all of the recoveries. We have not considered retraps as from the early years they wont have been reported and from recent years we dont know whether all have been submitted or not, so we are keeping to the knowns.

A quick and ready analysis of the new birds ringed by year, which totals 28,653 (to the end of 2014), is shown below. It can be clearly seen that capture and ringing activity increased 50fold in the years following 1999. Since then ringing totals have averaged c1700/year.

2015 season

This year we are going slightly later than we normally would to work around a full moon - we will thus be going at the beginning of August rather than the end of July. To date the team consists of 13 - some regulars, some returners and some Nan Ron virgins.
Not long now.....

Tail end Charlies

Two birds notified recently, one of a bird (2700081) caught on Nan Ron on the 29th July 2014 and recaptured 27 days later 27km down the coast at Faraid Head, and another (2682142) originally caught on Nan Ron on 29th Jul 2013 and caught at the same ringing session at Faraid Head as the former bird this time 392days had elapsed between captures. Thanks to TC for catching our birds!

Outstanding

These are the results of the ENR to ENR retraps.
This year thirteen birds were recaptured wearing years placed on them previously at Nan Ron - in between they will have covered many thousands of miles.

2531232, ringed in 2001, so 13 years old.
The oldest recorded STOPE was 31 years, 11 months and 9 days.

2625400, ringed in 2007, 7 years old

2638919, 2641478 both 5 years old.
2668593, 4 years old.

Seven birds were two years old, twelve one year old, and nine birds were same year retraps.

Outstanding are...

...our own retraps on Nan Ron from year to year. Hopefully time over the next couple of weeks will permit me to get on top of this.
The attendee list for 2015 already has names upon it.

Run of recoveries 3.
