Stormies that became Barn Owl fodder.

Following examination of all of the Barn Owl pellets collected off the island the following rings from these individuals were found.

2601039 ringed 2005 (4035 days)
2658382 ringed 2010 (2190 days)
2659456 ringed2011 (1825 days)

Obviously the Barn Owl is not discriminatory regarding the age of its prey.

Recoveries

A picture to start, black and white to add a bit of atmosphere if any is needed.

Forty-three retrap notifications were received following the visit to ENR of the Bache, Shearwood and McShane partnership.
From these 2608968 was the oldest being a bird originally ringed in 2007 (3274 days old). Next were two birds each from the years 2009, 2011 and 2012 making them 2536, 1803 and 1445 days old respectively. Interestingly no birds were retrapped from 2010.
There were fifteen retraps from birds originally ringed in 2014 with ages from 709-713 days. Not surprisingly there were 21 retraps of birds from 2015 - 329-336 days old.
