Don’t Ignore the Barnacles – they’re Actual Birds


Severe birders might have an obsessive curiosity in birds, however one factor they universally don’t like are birds which, they imagine, aren’t correctly wild. It’s taken a very long time for the purists to get used to the quite a few Pink Kites we now have in England, all descended from captive-reared birds that had been launched initially over 30 years in the past. Pheasants, launched in nice numbers for taking pictures, are regarded with disdain, whereas no one has a very good phrase to say concerning the flocks of Rose-ringed (Ring-necked) Parakeets that now squawk noisily in all of the London parks.

There’s one downside with this strategy, as it could result in birds being ignored. Right here in Suffolk we now have spectacular wintering flocks of Barnacle Geese, usually numbering 1000 birds or extra. The purist birders take little curiosity in them, concerning them as no extra attention-grabbing, or thrilling, than the flocks of Canada Geese which have lengthy been established within the county. In keeping with Suffolk Birds 2022 (the annual chicken report), “the birds within the county are a part of a naturalised inhabitants”. Nonetheless, although there have been information of feral Barnacle Geese nesting in Suffolk for a few years, the variety of pairs stay small, and definitely not adequate to account for flocks of the dimensions now seen each winter. Considerably, in 2022 there have been no information of those geese nesting efficiently wherever in Suffolk.

So the place do these geese come from? My guess is that they’re birds that transfer throughout from the Netherlands for the winter. The European Breeding Hen Atlas 2 makes attention-grabbing studying. “Initially confined to the Arctic, breeding [of Barnacle Geese] is now confirmed all through a lot of the Baltic coast S North Sea. This alteration is clear as an example within the Netherlands, the place the rising resident Dutch inhabitants is taken into account to be drawn from birds breeding across the Barents Sea and wintering within the Netherlands.” It goes on to say that the Dutch inhabitants is estimated at 16,000-22,00 pairs. The Atlas was revealed in 2020, so these numbers might have been grown since then. 

The Atlas attributes “the speedy improve of Barnacle Geese to a number of components”, of which an important appears to be improved safety of the Svalbard and Russian populations. As these geese unfold naturally as nesting birds via the Baltic, then into Denmark and Holland, it’s hardly stunning that they need to seem in Japanese England. It’s lower than 200 miles from the Suffolk coast to that of the Netherlands, a straightforward flight for a robust migratory chicken equivalent to this goose. 

Barnacles are engaging geese which have lengthy been common in wildfowl collections

In keeping with the Atlas, the mixed inhabitants for the Russian, Baltic, Netherlands inhabitants is round 770,000 people, which is an terrible lot of geese. I’ve watched migrating flocks of Barnacles streaming previous the Baltic island of Öland within the autumn. The numbers heading south are big, a lot so that you simply assume that the subsequent day the flocks can be smaller, as there can’t be many extra to come back. You’re unsuitable, for the subsequent day, and the subsequent, the flocks hold flying previous in undiminished numbers. It’s spectacular stuff.

Intriguingly, the inhabitants of Darkish-bellied Brent Geese has additionally elevated massively throughout the identical interval, however the birds present no indicators of colonising Europe, and there are hardly any information of them nesting away from the arctic tundra. (A pair did lay infertile eggs in Iceland in 2018, however that’s about the one report I can discover). Considerably Brent have by no means bred prolifically in captivity, in contrast to Barnacles.

There’s a sure magic within the migratory geese that fly to us yearly from the arctic.  Birds which have bred in Holland and easily flown throughout the North Sea might lack the identical attraction, but it surely does appear sure that they’re descendants of pure wild birds, not from captive inventory. Barnacles are energetic, entertaining geese, attractively marked and with neat proportions. I for one actually get pleasure from seeing the flocks that now winter on the Suffolk coast, and really feel that it’s excessive time that we took extra curiosity in them and their actions. In our neighbouring county of Norfolk there’s an rising inhabitants of nesting Barnacles, most of that are ringed. Regardless of making an attempt, I’ve didn’t see rings on any of the birds within the Suffolk flocks. Dismissing them as “naturalised” doesn’t do them justice.
