My first thought was also weaver, but that only explains the female.
The photos of the male were hard to see, but he doesn't look like any weaver I've ever seen, even mid-moult.
I was guessing that they're the same species?
Combassou (and perhaps paradise whydah) are the only two I can think of that would explain both birds.
But as
Colt
mentioned, they could very well be two different species. You could have a female weaver and a combassou male, for instance.
Also, remember that female weavers have a very “generic” look to them in that they can look very similar to the females of other species. (In particular, species where the males moult into a seasonal plumage.)
If you look at the female combassou finch and the female paradise whydah, you'll see they look just like a female weaver, also with the stripe over the eye.
I think you'll need to wait until the male moults into his seasonal colors to know for certain!
Sometimes, when I have an unidentified bird, I make note of how they relate to other birds of the same species.
Do they interact a lot and seem to relate well? Do they seem to have a bond and an innate understanding of each other's body language?
It's a bit hard to explain, especially if you're not super familiar with birds, but birds of the same species have an ease with each other; an innate understanding. It's a familiarity; it's clear they speak the same language.
I have a female weaver and a pintail whydah paired together. And after watching them for a bit, it became very clear to me that they weren't the same species. They just don't relate to each other.
They're peacefully coexisting, but they don't share the innate understanding or closeness that you generally see with birds of the same species.
For instance, they never physically touch each other and never vocalize/“speak”
to each other. They don't sit or sleep together. There's always a few inches between them. If I had to describe their relationship, it would be non-existent/totally indifferent.
In short, it's clear they speak two different languages. (That's not to say that two birds of different species can't form a bond --- they can. But it generally takes time. Just as it would take time to form a relationship with another person from a totally different culture who speaks a totally different language. But that relationship may always lack the innate connection you have to the person from your own culture, who speaks the same language.)
