Barnacle goose X61, Pennington Flash


Appearances can be deceiving, first impressions can be misleading. I arrived at the flash this morning to find the place shrouded in mist and drizzle, in fact just the kind of conditions that at this time of year can often produce something good. I was full of anticipation when I arrived at Horrock's hide, but what I wasn't expecting was a barnacle goose. 

At first it was flying around calling as if looking for a place to land. Eventually it seemed decide that the Spit was the best place and it landed in the water near the end, about 150m away from me. While it had been flying I noticed that it had a yellow ring on its left leg and this immediately piqued my interest because I knew that some birds from Svalbard have yellow rings on their left legs. However I needed to read the code on the ring and this proved easier said than done. The bird was very wary and though it was obviously considering coming out of the water even the slightest noise or movement from a nearby duck spooked it and it moved away. One time it partially came out but not enough for me to read the ring and then all of the lapwings on the end flew up and up went the goose with them, flying high calling, I watched it disappear over the ruck and thought it was gone, but after about five minutes I heard it again and there it was flying high over the flash. Now it flew south and was lost behind the trees, but again it returned as the drizzle continued to fall. Eventually it landed back in the same location just off the spit, and though it walked out of the water a little, I still couldn't see below its knees. Again it was constantly looking around nervously and after a while it flew again, but this time just a short distance and joined up with about 20 Canada's in the middle of the flash, yet even now it didn't seem settled, keeping a respectable distance from its larger cousins. Surely this was a wild bird? It was so wary. 

My only concern was that it's a bit early for Svalbard birds, which don't usually arrive in Scotland until October, and also there is a feral population of Barnacles in the Knowsley / St Helens area which now numbers over 200 birds. On the other hand large numbers of pink-footed geese have been passing over during the past couple of days, with 10,000 currently on the Ribble marshes and many more flying east over North West England heading for Norfolk, so who knows, perhaps this bird had been travelling with them and got disorientated in the mist and drizzle and ended up on the flash. I still hadn't read the ring.....

However, the Canada goose flock made it's way towards the car park with their smaller companion straggling along behind them and eventually they made it to the shore and walked out. This is not a good place to be for a bird that want's to be considered wild, and now it didn't seem so wary, allowing me to approach with 10m and sit down on a bench to take a few photos. The code on the ring read X61 and a quick bit of research revealed that it was part of a project to ring naturalised geese in the UK with the aim of learning about their movements. Kane Brides has confirmed that the bird was ringed at Knowsley in July this year and also commented that "The flock seems to have dispersed and moved around in the past few days, with Knowsley ringed birds having been found in Oxfordshire and Surrey in the past few days!"

So in the end it wasn't from Svalbard but it still made for an entertaining morning !


Despite there being such a large feral breeding population as close as Knowsley, barnacle goose is still a very scarce bird at the Flash and perhaps surprisingly this was only my third ever record in around 40 years, though it is possible that in the first 20 or so of those years I didn't record them, perhaps dismissing them as just feral geese. Svalbard barnacles have been recorded at the Flash, previously, the last was on 10th October 2013 when one of a flock of 10 barnacles on the spit had an orange darvic ring, FIF which was confirmed as having been ringed in Svalbard.
