I suppose it could be Ploceus, but the structure doesn't feel right... It feels bulkier that most weavers

Sorry, as you probably suspect, this photo is too difficult to tell much. It's hard to get a sense of the colouration vs. light and even the general shape seems suspect (is it fluffed up?). I'm not hugely familiar with East African birds (though there is considerable overlap with southern Africa where I'm based), but I'm gonna say this one is stuck at passerine sp. The people at BirdForum are great with African birds, but be warned, they can seem a bit mean spirited at times.

I found another photo. Not sure if it adds anything of value.

Hi, On a recent trip to the US, I saw this individual in New Orleans, LA. I initially wrote it off as a colour aberration, but I just noticed the vibrant leg colour as well. I'm now wondering if this bird should be reported as an x on the eBird list? Thanks!

Hi, How should I report these two domestics on eBird? One is Greylag, right? Is the white one a Domestic Swan Goose?

The audio seems not to have uploaded properly. I'm trying again - it can also be found here: https://www.inaturalist.org/observations/135331971

Hi, I was in New Orleans yesterday and heard this crow that didn't sound like a crow as I know it. I've uploaded the audio and a photo, could this be a Fish Crow? 2022-09-16 1153.wav

Seconded

I love seeing African birds here--it gives me something to actually answer. Yes, this bird looks very good for a Southern Grey Headed Sparrow as mentioned above

Hi, These were taken at the Port of Ensenada in Baja. I know I'm looking at some western gulls, but is there anything else pictured? --many thanks!

Okay, North American birds aren't my specialty but let me just throw out Northern Gannet. I also struggle to see this as a gull but think the Gannet might match the OP's description a bit better than a petrel.

Yes, green-winged Pytilia
