Olive-backed Sunbirds (Cinnyris jugularis)
first photo is a male looking down on those female sunbirds. males has Bright yellow underparts with an iridescent dark blue or black throat and upper breast. it's common at the cemetary park. they can adapt to urban areas easy.
The sunbird has a masterful beak. These are nice clear shots with great detail.
I'm amazed by the colorful Olive-backed Sunbirds (Cinnyris jugularis). I've always loved birds. Your photos are truly outstanding. Thank you for sharing them with us.
