Errors in the German list

31 Jul 2019 20:15 #1588 by Mathieu Waldeck
Hello,
I'm new to Bubo, so please excuse if this is the wrong place to post this.
I just created some lists for Germany and stumbled upon several weird species. Maybe someone could correct the status for the follwoing species:

The following species are not on the German list, or just as category E:
Red-legged Partridge
Northern Bald Ibis (Reintroduction program in place, but the birds are still very heavily dependent on humans)
Snowy Egret (has been removed from the list)
Western Reef Heron
Slaty-backed Gull
Lanner Falcon
Mountain Chiffchaff
Eastern Orphean Warbler
Spotless Starling
Scaly Thrush

The following are not really rarities (anymore):
Northern Gannet
Shag
Caspian Gull
Pomarine Skua
(Red-footed Falcon)
Yellow-browed Warbler

The following should IMHO be flagged as rarity:
Common Loon
Stone-curlew
Black-winged Stilt
Red-necked Stint
Great Snipe
Glaucous Gull
Iceland Gull
Long-tailed Skua
Puffin
Azure Tit
Greenish Warbler
Aquatic Warbler

The following species are currently ommitted on Bubo (though their status is still disputed in Germany, however the relevant listing committee (Club300) currently has them listed):
Black Swan
Bar-headed Goose
Swan Goose
Yellow-headed Amazon

The current german list can be found here , however many decisions there are extremely odd and therefore the list is not popular with german birders to say the least. I'd advise against following this list for Bubo...

Hi Mathieu

Many thanks for these. Our German list hasn't had much of a sense check since we first put it online! I've applied all the updates you suggest: do please point out any others.

How does the list you linked compare to the Club 300 list ?

A new official list for Germany was long overdue, with the last one from 2005 by Barthel & Helbig.
Barthel & Krüger now finally published a new list last winter, but Club300.de and most birders I know, even some official sites decided to ignore this new list for the following reasons:

Weird and unwanted name changes: Imagine the BOU decided to change Common Loon to Great Northern Diver, without explanation and without any need for these name changes. That's what happened to several dozen vernacular bird names like Ziegenmelker, Katzenvogel or Zwergdrossel.

Inconsistencies with category C species:
A few years back a paper was published by the 'committee for invasive birds' (Fachgruppe Neozoen der DO-G). Using a scientifically consistent approach, using (more or less) well-defined rules, they identified several new invasive species that qualified for Category C (e.g. Yellow-headed Amazon, Alexandrine Parakeet, Swan Goose, etc.). There was still some discussion about some of these decisions (e.g. Sacred Ibis, Chilean Flamingo (which was not added), Swan Goose), but at least now there was some solid scientific framework in place and birders were getting used to the changes. For the new list ALL these decisions were revoked, including no-brainers such as Alexandrine Parakeet or Bar-headed Goose. Explanations were extremely scarce.

Perhaps most importantly, the approach to vagrants of uncertain provenience is extremely inconsistent. White-throated Sparrow is cat E, Song Sparrow Cat D and Northern Parula Cat A. It's absolutely unclear how these decisions are made.
Demoiselle Crane was admitted to Category B on the basis of a bird from Heligoland, more than hundred years ago, however 7 subsequent records, without any signs of previous captivity are placed in Category E...
Azure Tit on the other hand is placed in A, where I'm not aware of a single "good" record. I could list about two dozen more species where the categorization is very arguable, e.g. Rose-breasted Grosbeak, Brown-headed Cowbird, Pin-tailed Sandgrouse, Fox Sparrow, Cinereous Vulture...
Furthermore Band-rumped Storm Petrel (2 records) was deleted without any further comment.

I hope you can now understand my concerns with that list. The Club300 list isn't perfect either, nothing will ever be, but it's much closer to the truth if you ask me.

Thanks for the detailed explanation. It sounds like we should align as closely as possible with Club 300 unless there are clear species with a lack of consensus. If you notice any discrepancies do let us know, so we can try to get the most helpful list possible!
