This Worldmap data set is seriously flawed, as far as Cape Teal is concerned it's a work of pure fiction.

Is this Worldmap data published in a peer reviewed paper ? reference please.

Where did they get their original data from ? curious that Durham / BirdLife did not ask us for any data.

Have they used recent data (unpublished) from the new Kenya Atlas or only the maps in Lewis & Pomeroy 1989 ?

Did they have access to the raw data for the Uganda, Zambia, Malawi, Southern Africa, Liberia, Ghana, Ethiopia, Somalia (any others out there?) atlases

How did they differentiate between known "range" and extralimital records ? The std atlases do not unless it's in the text. It's the same black blob for a single record as it is for a thousand.

How did they differentiate between "old" literature records, many of which are specimens and are often incorrectly labeled with poor locality data and rather many identification errors.

and...where did they get their "current" climate data from ? the Uganda Atlas habitat predictions uses data from only 16 rainfall stations and all of us working in Africa understand how inaccurate "government data" can be.

Ken, I would strongly recommend you check carefully those species you are familiar with before you get too excited and most certainly before u even think about making recommendations to African governments regarding conservation issues based on these highly theoretical range changes.
