Detection is worse now?

[HinzundKunz]

In my experience, the detection of birds in East Africa has become worse since at least March (that's when I got back to Tanzania and noticed). Birds that used to be detected just fine aren't recognized any more, or are misidentified as something else (most often house sparrows). Is there a reason for this, and will it become better again?

Please provide missidentified samples for us to check.

Will do so. I'll have to reinstall birdnet for this, though. Birdnet live works differently, and I've been using that for a while now.
I also use Birdnet-Go for 24/7 detection, and it used to detect and recognize better before.
I'll try and get some samples this evening.

Sorry for the delayed reply. First we had a power outage (Welcome to Africa ;-) ), and when I tried to reply via email with sample files attached, the size was too big...
I've uploaded a couple of files to a Google Drive folder:

All of these recordings were identified as House Sparrow only. There are Red-billed Firefinch, Red-cheeked Cordonbleu, and Black-winged Bishop in it which should have been identified as well.
Also, there are two more that I uploaded to ebird. The first one is a Miombo Wren-warbler that got misidentified as House Sparrow. The link is from a recording done with Merlin, but the same time and location, I used birdnet on it as well:

And the second is just from the day before yesterday. Little bee-eater (with some Firefinch etc. in the background) being misidentified as Wire-tailed Swallow:

I'll give it a look, also: BirdNET v3 is on its way to the analyzer and my guess is that it will likely improve performance anyway.

Just now I got another false positive. Identified as Wire-tailed Swallow, but in truth Red-billed Firefinch.

I can't upload it it seems... I'll put it on the Google Drive to the others then...
