Taiga Bean Geese autumn 2023


This year’s variable weather has continued with flooding again at the weekend (August has beaten all records for rain) but since then it has been nice warm and sunny and is forecast to continue that way which makes birding more enjoyable.

The Scottish Taiga Bean Geese moved south to their traditional Norwegian (Glomma) staging grounds already on 17 August this year and I paid an unsuccessful visit to look for them on 21 August but another attempt yesterday was far more successful. The birds were in the field I was hoping to find them using (a field they have used many times before which fits with them being birds of habit) and they were readily viewable from a road. A count of 101 was pretty good but I counted only 5 family groups totalling 9 young but this low level of productivity also is typical of this population. I identified 3 tagged birds including the sole bird in this group still sending a GPS signal. This flock will be here for probably another month before heading for Scotland either directly or perhaps via Denmark.

After this I visited a very flooded Årnestangen where the nice weather had got a few raptors in the air. Best of all was a juvenile Honey Buzzard flying together with dad and frequently interacting with passing Buzzard and Sparrowhawk. Dad was passing for junior and the whole thing looked like flying practice with supervision.
