Aden Yemen Garden (1 Viewer)

Hello,
Yesterday while I was watching the walled garden at the location I am staying in in Aden, Yemen, a group of 7 little birds desended. I tried to photograph them with my cell phone through my binoculars. It did not work great.
I am trying to ID what I saw. The best guess I have is perhaps they were Menetries's Warbler (Sylvia mystacea). this is a link to a photo

I am wondering if anyone can perhaps point me in a direction with this.
They were small and made alot of vocalization. the breast and stomach were a bright white, the back a mid brown and the tail and primaries seemed to make a darker band separating the white below and the brown above as the birds walked about on the stone walkway in the garden (perhaps feeding on grass seeds?)
thanks for any helpf with this

I'd go for African Silverbill.

African Silverbill I think.

Agree with the others; African Silverbill

Thanks,
Silverbill was also an initial thought for me , especially with the way the dark tail contrasted with the back. I went away from that when it seemed that I was not noticing anything particularly silver about the bills. But it really seems to be the best call here, in total. Thanks
