The Swifts are coming 2026: BirdNet & BirdWeather

A slow trickle of swifts are returning to Britain

but by the end of this month, it will be a flood.

So its time to switch on our swift-caller & keep an eye on our 3 nests!

BirdNet-Pi Species Stats: post analysis graphing

 

I like graphs!

 

And I like the annual count-by-month bar graph in Species Stats

But I’m less keen on the hourly chart.

BirdNet Systems Testing #4: looking through the wrong end of the scope

Another day, another opinion

My earlier test results were still worrying me

Had I made some terrible mistake?

BirdNet Systems Testing #3: single call repeatability test

One final test method

 Is BirdNet really so bad?

or is there an 'age related' issue, i.e. 'me'

BirdNet Systems Testing #2: a critical review from AI

I'm still troubled by my initial test results

And I haven't made any progress on further testing, 

so I decided to get a second opinion.

BirdNet Systems Testing #1

I thought this would be easy

 Just run BirdNet-Pi alondside BirdNet-Go

Then choose which system to use in the future.

BirdNet-Pi: streaming the microphone

This is about audio streaming from my system's mic.

I wanted to use AI to do all the thinking & lead me through the config.

But it didn't turn out to be so simple.

The Swifts are coming! ...hopefully

 Our BirdNet-Pi system has gone crazy!

 

Its suddenly reporting hundreds of Swift calls.

So what going on?

BirdNetPi: false positives & %conf level

 I don't like false positives 

...but I don't want to miss anything!

That's the dilemma when setting the BirdNetPi %confidence level.

BirdNet-Pi: export audio recordings as video

Posting audio detection recordings for others can be tricky.

 

It seems that apps like Facebook don't support audio files.

So I was looking for an easy way around this issue.

BirdNet-Pi: USB audio module testing

I've bought a couple more modules

so thought I'd do some tests to compare performance.

This post concerns the use of USB audio modules in connection with miniature electret microphone capsules.

BirdNetPi: 12 months on, what now?

My system has collected a lot of data.

Can it tell me anything?

And what do I do now?

BirdNet-Pi: upgrading the drive

Time to replace the uSD drive for a larger USB drive.

 

This is not rocket science...

...but once again, due to my poor memory, I need to record the procedure.

BirdNet-Pi: Species Stats

We are well into the 2024 BirdBox season.

 

Last year, blue tits made use of our new woodcrete bird box...

...but this year the great tits are having a turn.

whoBIRD: running in Costa Rica

Costa Rica has around 900 species of birds!

It is possibly the most bio-diverse country in the world.

So where better to take a bird call id application like whoBIRD which stores all detections in a readable database?

BirdNet-Pi Portable Vs whoBird

Which one should I take with me the next time I'm away from home?

BirdNet-Pi Portable: chart info mods

My BirdNet-Pi Portable system gets taken to places away from home!

So its important that the daily records are properly labeled.

BirdNet-Pi: more thoughts on microphones & audio

There's a lot of talk on the Github Discussions page about microphone quality.

So naturally I have been giving the matter some consideration and have conducted a few simple checks.

BirdNET-Pi: direct file editing

I've been editing files on my BirdNet-Pi systems via my laptop.

This post just describes the procedure I use.

BirdNet-Pi: portable operation, mics & bird dogs

Its been an interesting couple of weeks.

I've experimented quite a bit with my BirdNET-Pi system and even built a second system.
