Birding in Kenya: Nairobi National Park bird identification

I managed to leave my field guide at home when visiting Kenya last month (rookie error when traveling in a new country!) so I wasn’t able to pin down some of the IDs in the field. I took these photos in Nairobi National Park. Any thoughts on each bird’s identification would be much appreciated – feel free to add comments below.

My feeling is that this is an Isabelline Wheatear given the black alula and the extent of white in front of the eye, but I have no experience separating Isabelline from Northern Wheatear.

I saw a lot of pipits in Nairobi National Park and most resembled African Pipit, but I have seen literature mentioning “Nairobi Pipit” and the likes so I thought I’d seek opinion on these. Pipits 1 and 2 remind me of African / Grassveld and Pipit 3, given its longer-legged appearance and bulkier giss I’d lean towards Plain-backed. Any thoughts on these pipits?

Sorry, but I had to include some Cisticolas and some rather rubbish images to boot. I realise habitat and call provides a bit more context, but does anyone have any thoughts?

Thanks in advance,
