International census: update (14th October)

Thanks to all the observers who have been sending in count information from all corners of the flyway - a comprehensive aerial survey of Western Iceland (Gudmundur & Svenja) , NW and NE Scotland (John and Bob), and as far south as northern France (Alain) - where geese have not made landfall as yet.

The preliminary total is just over 32,000 individuals of which around 10% are young birds born last summer and which have made it this far. That is from the major sites (Strangford, western Iceland and Lough Foyle in addition to a range of sites holding smaller numbers).

Earlier today, the flock of 178 at Dundrum Bay (see picture) comprised a lot of family units (28) with an average of number of juveniles per family of just under 3 (2.93 to be precise). So a pretty successful year. Just under half of this flock were juveniles (82 of 178; 46%) and you wouldn't want to be estimating overall productivity just on this small sample!!

Thanks for all your efforts over recent days - count data from various parts including the E coast (Down - Dublin), Tralee and Castlemaine will just about finish the assessment for this autumn. The total may well rise to over 35,000. Watch this space...
