Hi Steve,
ok! list is below. This is (hopefully) all the (Kenyan) species as listed in the Stephenson & Fanshawe FG (2002 edition) that are affected in some way by a split (or in a few cases a proposed split) in any of the 4 big global checklists (IOC, Clements, Bird Life International, Howard and Moore) relative to how they are described in the FG. In some cases the taxa occurring in E Africa have been split into multiple spp (marked with an asterisk), in other cases the split will be with extralimital forms.
There's a few widespread spp. like Cattle Egret, Barn Owl, Yellow Wagtail that if I was being ultra picky I might have included but I figure you'll be aware of all of those already.
I don't really care about cleansing my FG of outdated and field guide splits so they aren't included on the list below. There are a few though, Heuglin's Gull, Barbary Falcon, Schalow's Wheatear etc.
It's too big a job to detail all the splits here but you should be able to work them all out with the help of IOC, Bird Life International and Avibase websites (the comparison checklist available on the IOC website is a big help). If there are any you are genuinely stumped by feel free to ask.
Any splits affecting spp. that don't occur in Kenya, or that don't affect the forms listed on the Kenyan checklist, will not have been captured so hopefully someone else can point you in the direction of any of those.
cheers,
James
